Save in JPEG format

You can use the

Save As

command to save CMYK, RGB, and grayscale images in JPEG (*.jpg) format. JPEG compresses file size by selectively

discarding data. You can also save an image as one or more JPEG using the Save

For Web

& Devices command.

JPEG supports only 8-bit images. If you save a 16-bit image to this format, Photoshop automatically lowers the bit

depth.

To quickly save a medium-quality JPEG, play the

Save As

JPEG Medium action on the file. You can access this action by choosing Production from the Actions panel menu.

1 Choose File >

2 Save As

3 , and choose JPEG from the Format menu.

4 In the JPEG Options dialog box, select the options you want, and click OK.

Matte Offers matte color choices to simulate the appearance of background transparency in images that contain

transparency.

Image Options Specifies 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 Specifies the format of your JPEG file. Baseline (“Standard”) uses a format recognized by most web

browsers. Baseline Optimized creates a file with optimized color and a slightly smaller file size. Progressive displays a

series of increasingly detailed versions of the image (you specify how many) as it downloads. (Not all web browsers

support optimized and Progressive JPEG images.)

Note: Some applications may not be able to read a CMYK file saved in JPEG format. Likewise, if you find that a Java

application can’t read a JPEG file, try saving the file without a thumbnail preview.
