Choosing publish settings for JPEG files

The JPEG format lets you save an image as a highly compressed, 24-bit bitmap. Generally, GIF is better for exporting line art, while JPEG is better for images that include continuous tones like photographs, gradients, or embedded bitmaps.

Flash exports the first frame in the movie as a JPEG, unless you mark a different keyframe for export by entering the frame label #Static.

Publish settings for JPEG format

To publish a JPEG file with the Flash movie:

1 | Choose File > Publish Settings.
2 | Select the JPEG Image type. Enter a unique name for Filename, or select Use Default Name to create a file with the Flash filename plus the .jpg extension.
3 | Click the JPEG panel to display its settings.
4 | For Dimensions, enter a Width and Height in pixels for the exported bitmap image, or select Match Movie to make the JPEG the same size as the Flash movie and maintain the aspect ratio as your original image.
5 | For Quality, drag the slider or enter a value to control the amount of JPEG file compression used.
| Lower image quality produces smaller files, while higher image quality produces larger files. Try different settings to determine the best trade-off between size and quality.
| Note: You can set the bitmap export quality per object using the Bitmap Properties dialog box to change the object's compression setting. Selecting the default compression option in the Bitmap Properties dialog box applies the Publish Settings' JPEG Quality option. See Setting bitmap properties.
6 | Select Progressive to display Progressive JPEG images incrementally in a Web browser, to make images appear faster when loaded over a slow network connection.
| This option is similar to interlacing in GIF and PNG images.
7 | To save the settings with the current file, click OK.
