Saving files in PNG format (Photoshop)

You can use the Save As command to save RGB, indexed-color, grayscale, and Bitmap-mode images in PNG format. For more information on the PNG format, see PNG.
Note: You can also save an image as one or more PNG files using the Save for Web command (Photoshop) or the Save Optimized command (ImageReady). For more information on optimizing images, see Optimizing images.

To save a file in PNG format:

1. Choose File > Save As and choose PNG from the Format menu.
2. Select an Interlace option:
• None displays the image in a browser only when download is complete.
• Interlaced displays low-resolution versions of the image in a browser as the file downloads. Interlacing makes download time seem shorter, but it also increases file size.
3. Click OK.

Saving files in JPEG 2000 format (Photoshop optional plug-in)

To save files in the JPEG 2000 format, the optional JPEG 2000 plug-in must be installed in Adobe Photoshop CS/Plug-Ins/Adobe Photoshop Only/File Formats. The optional JPEG 2000 plug-in can be found on the Photoshop CS installation CD in Goodies/Optional Plug-Ins/Photoshop Only/File Formats. You can save images in extended JPEG 2000 (JPF) format, which provides an expanded set of options compared to the standard JPEG 2000 (JP2) format. However, you can make files JP2 compatible by selecting the appropriate option in the JPEG 2000 dialog box. For more information on the JPEG 2000 format, see JPEG 2000 (Photoshop optional plug-in).
Note: You cannot save Duotone, Multichannel, or Bitmap mode images in JPEG 2000 format. To save these files as JPEG 2000, first convert them to RGB color.

To save a file in JPEG 2000 format:

1. Choose File > Save As, and choose JPEG 2000 from the Format menu.
2. Specify a filename and location, select saving options, and click Save, which opens the JPEG 2000 dialog box.
Important: If you want to save a JP2-compatible file, you must select the ICC Profile option (Windows) or the Embed Color Profile option (Mac OS) in the Save As dialog box. Otherwise, the JP2 Compatible option will be unavailable in the JPEG 2000 dialog box. The JP2-compatible option slightly increases the JPF file size. Keep in mind that JP2 viewers are not required to support ICC profiles and metadata present in JPF files, so color fidelity and other features may not work as expected.
3. (Optional) Enter a value in the File Size text box to set a target size for the saved file. The value in the Quality text box will adjust to the best quality for the file size you enter.
4. Do one of the following to specify the image quality:
• Select Lossless to compress the image without losing image quality. Selecting this option creates a larger file.
• Deselect Lossless to create a smaller file. Then drag the Quality pop-up slider or enter a value in the Quality text box to specify the image quality. A higher quality value results in better image quality and a larger file size.
If you specify an image quality that conflicts with a target file size you entered previously, Photoshop automatically changes the value in the File Size text box.
5. Select Fast Mode for faster previewing or encoding of the image. File size control, progressive optimization, and lossy with integer wavelet filter are not supported in Fast Mode.
6. Select Include Metadata to include file information. If your image file contains paths and you wish to store the paths information in the JPEG 2000 file, the Metadata option must be selected.
Deselect the Include Metadata and Include Color Settings options to make the image file size smaller.
7. Select Include Transparency to preserve transparency that exists in the original image. The Include Transparency option is dimmed if the image does not contain transparency.
8. Select JP2 Compatible to create a file that can be displayed in viewing software that supports standard JPEG 2000 (JP2) format but does not support extended JPEG 2000 (JPF) format.
9. Click the Advanced Options button to set the following options:
Compliance
Chooses the types of devices with which the file is compliant. Currently, only general devices (such as Web browsers) are supported.
Wavelet Filter
Specifies the type of numbers (coefficients) used to encode the file. Float is more accurate but cannot be used for Lossless compression. Selecting the Lossless compression option automatically sets the Wavelet Filter option to Integer.
Choose Float or Integer depending on your image and the result you want. Integer is usually the best option for an overall consistent appearance in the image. Float may sharpen the image but could cause it to lose some quality around edges.
Tile Size
Chooses the size of the tiles used in the image. When low quality values are used to optimize images smaller than 1024 x 1024 pixels, using the largest tile size will produce better results.
A tile size of 1024 is best for most images. When creating files with small dimensions (for cell phones, and so forth), a lower tile size should be used.
Metadata Format
Select the metadata format(s) to include in the image file. JPEG2000 XML is JPEG 2000-specific XML data; this option is only available if the image file contains this data. XMP is File Info data and EXIF is digital camera data.
Color Settings Format
Select the Color Settings Format to include in the image file. The ICC Profile option includes the full ICC profile specified in the Save As dialog box and is the default option. The Restricted ICC Profile option is intended for use in portable devices such as cell phones and PDAs. A Restricted ICC Profile must be in a JP2 file.
10. Choose an Optimization Order from the Order menu:
Growing Thumbnail
Presents a sequence of small thumbnail images increasing in size until they reach the image's full size.
Progressive
Presents an image that displays increasingly detailed versions of the entire image as data becomes available (for example, streaming over the Web to a browser). Progressive JPEG images have a slightly larger file size, require more RAM for viewing, and are not supported by all applications and JPEG 2000 viewing software.
Color
Makes the image appear first as a grayscale image, then as a color image.
Region of Interest
If your Photoshop document contains one or more alpha channels, you can choose an alpha channel to define a Region of Interest.
Once the alpha channel is loaded as a Region of Interest, choose an Enhance value to increase or decrease the quality of the Region of Interest relative to the rest of the image. Note that Enhance does not change the file size of the image, so enhancing the area inside the alpha channel will decrease the quality of the area outside the alpha channel (and vice versa).
The Region of Interest and Enhance options are not available if your Photoshop document does not have an alpha channel.
Note: The channel (alpha, spot, or Quick Mask) used to define the Region of Interest will be discarded in the final saved JPEG 2000 file.
11. To preview how the image will appear in JPEG 2000 viewing software, make sure you chose an Optimization Order in step 10. The Preview option takes into consideration how the image is optimized and will open the image accordingly. In the Download Preview area of the JPEG 200 dialog box, choose a download rate from the pop-up menu to view the estimated download time of the image, then click the Preview button.
You can use the Set Preview Zoom pop-up menu to zoom in or out of the image for better viewing. You can also use the Zoom tool and the Hand tool to adjust the viewing area of your preview.
12. When you're done setting options, click OK to generate the JPEG 2000 image file.

Saving files in JPEG format (Photoshop)

You can use the Save As command to save CMYK, RGB, and grayscale images in JPEG format. JPEG compresses file size by selectively discarding data. For more information, see About file compression and JPEG.
Note: You can also save an image as one or more JPEG files using the Save for Web command (Photoshop) or the Save Optimized command (ImageReady). For more information on optimizing images, see Optimizing images.

To save a file in JPEG format:

1. Choose File > Save As and choose JPEG from the Format menu.
2. In the JPEG Options dialog box, select the options you want, and click OK.
Matte
If the image contains transparency, choose a Matte color to simulate the appearance of background transparency. For more information on simulating transparency using the Matte option, see Optimization options for GIF and PNG-8 formats.
Image Options
To specify the image quality, choose an option from the Quality menu, drag the Quality pop-up slider, or enter a value between 0 and 12 in the Quality text box.
Format Options
Select Baseline ("Standard") to use a format recognized by most Web browsers, Baseline Optimized for optimized color and a slightly smaller file size, or Progressive to display a series of increasingly detailed scans (you specify how many) as the image downloads. Baseline Optimized and Progressive JPEG images are not supported by all Web browsers.
Size
To view the estimated download time, select a modem speed. (The Size preview is only available when Preview is selected.)
Note: Some applications may not be able to read a CMYK file saved in JPEG format. In addition, if you find that a Java application cannot read your JPEG file (in any color mode), try saving the file without a thumbnail preview.

Saving files in GIF format (Photoshop)

You can use the Save As command to save RGB, indexed-color, grayscale, or Bitmap-mode images directly in Compuserve GIF (known as GIF) format. The image is automatically converted to indexed-color mode. For more information about the GIF format, see GIF.
Note: You can also save an image as one or more GIF files using the Save for Web command (Photoshop) or the Save Optimized command (ImageReady). For more information on optimizing images, see Optimizing images.

To save a file in GIF format:

1. Choose File > Save As and choose CompuServe GIF from the Format menu.
2. For RGB images, the Indexed Color dialog box appears. Specify conversion options and click OK. For more information, see Conversion options for indexed-color images (Photoshop).
3. Select a row order for the GIF file, and click OK:
• Normal displays the image in a browser only when download is complete.
• Interlaced displays low-resolution versions of the image in a browser as the file downloads. Interlacing makes download time seem shorter, but it also increases file size.

Saving 16-bit-per-channel files in Cineon format (Photoshop)

RGB images that are 16 bits per channel can be saved in Cineon format for use in the Kodak Cineon Film System. For more information about the Cineon format, see Cineon.

To save a 16-bit-per-channel file in Cineon format:

Choose File > Save As and choose Cineon from the Format menu.

Saving files in BMP format

The BMP format is an image format for the Windows operating system. The images can range from black and white (1 byte per pixel) up to 24-bit color (16.7 million colors). For more information about the BMP format, see BMP.

To save a file in BMP format:

1. Do one of the following:
2. In Photoshop, choose File > Save As and choose BMP from the Format menu.
• In ImageReady, choose File > Export > Original Document, and choose BMP from the Save as Type (Windows) or Format (Mac OS) menu.
3. Specify a filename and location, and click Save.
4. In the BMP Options dialog box, select a file format, specify the bit depth and, if necessary, select Flip Row Order. For more options, click Advanced Modes and specify the BMP options.
5. Click OK.

Saving files in Photoshop Raw format (Photoshop)

The Photoshop Raw format is a file format for transferring images between applications and computer platforms. For more information about the Photoshop Raw format, see Photoshop Raw (Photoshop).

To save a file in Photoshop Raw format:

1. Choose File > Save As and choose Photoshop Raw from the Format menu.
2. In the Photoshop Raw Options dialog box, do the following:
• (Mac OS) Specify a File Type and File Creator, or accept the default values.
• Specify a Header parameter.
• Select whether to save the channels in an interleaved or noninterleaved order. 

Saving files in Photoshop DCS format (Photoshop)

DCS (Desktop Color Separations) format is a version of EPS that lets you save color separations of CMYK or multichannel files. For more information about the Photoshop DCS format, see Photoshop DCS 1.0 and 2.0 (Photoshop).

To save a file in Photoshop DCS format:

1. Choose File > Save As and choose Photoshop DCS 1.0 or Photoshop DCS 2.0 from the Format menu.
2. In the DCS Format dialog box, select the options you want, and click OK.
The dialog box includes all the options available for Photoshop EPS files. For more information, see Saving files in Photoshop EPS format (Photoshop). Additionally, the DCS menu gives you the option of creating a 72-ppi composite file that can be placed in a page layout application or used to proof the image:
• DCS 1.0 format creates one file for each color channel in the CMYK image. You can also create a fifth file: a grayscale or color composite. To view the composite file, you must keep all five files in the same folder.
• DCS 2.0 format retains spot-color channels in the image. You can save the color channels as multiple files (as for DCS 1.0) or as a single file. The single-file option saves disk space. You can also include a grayscale or color composite. 

Saving files in Photoshop EPS format (Photoshop)

Virtually all page layout, word processing, and graphic applications accept imported or placed EPS (Encapsulated PostScript) files. To print EPS files, you should use a PostScript printer. Non-PostScript printers will only print the screen-resolution preview. For more information about the Photoshop EPS format, see Photoshop EPS.

To save a file in Photoshop EPS format:

1. Choose File > Save As and choose Photoshop EPS from the Format menu.
2. In the EPS Options dialog box, select the options you want, and click OK:
Preview
Creates a low-resolution image to view in the destination application. Choose TIFF to share an EPS file between Windows and Mac OS systems. An 8-bit preview delivers better display quality but larger file size than a 1-bit preview.
Encoding
Determines the way image data is delivered to a PostScript output device:
• Choose ASCII or ASCII85 if you're printing from a Windows system, or if you experience printing errors or other difficulties.
• Binary produces a smaller file and leaves the original data intact. However, some page-layout applications and some commercial print spooling and network printing software may not support binary Photoshop EPS files.
• JPEG compresses the file by discarding some image data. You can choose the amount of JPEG compression from very little (JPEG Maximum Quality) to a lot (JPEG Low Quality). Files with JPEG encoding can be printed only on Level 2 (or later) PostScript printers and may not separate into individual plates.
Include Halftone Screen and Include Transfer Function
Control print specifications for high-end commercial print jobs. Consult your printer before selecting these options.
Transparent Whites
Displays white areas as transparent. This option is available only for images in Bitmap mode.
PostScript Color Management
Converts file data to the printer's color space. Do not select this option if you plan to place the image into another color-managed document. Doing so may disrupt the color management.
Note: Only PostScript Level 3 printers support PostScript Color Management for CMYK images. To print a CMYK image using PostScript Color Management on a Level 2 printer, convert the image to Lab mode before saving in EPS format.
Include Vector Data
Preserves any vector graphics (such as shapes and type) in the file. However, vector data in EPS and DCS files is only available to other applications; vector data is rasterized if you reopen the file in Photoshop.
Image Interpolation
Anti-aliases the printed appearance of a low-resolution image.
