Specify publish settings for JPEG files

The JPEG format lets you save an image as a highly compressed, 24‑bit bitmap. Generally, GIF format is better for exporting line art, and JPEG format is better for images with continuous tones, such as photographs, gradients, or embedded bitmaps.

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

  1. Select File > Publish Settings, click Formats, and select JPEG Image.
  2. For the JPEG filename, either use the default filename, or enter a new filename with the .jpg extension.
  3. Click JPEG.
    Dimensions

    Enter values for width and height in pixels for the exported bitmap image, or select Match Movie to make the JPEG image the same size as the Stage and maintain the aspect ratio of your original image.
    Quality

    Drag the slider or enter a value to control the amount of JPEG file compression. The lower the image quality, the smaller the file size, and the reverse. To determine the best compromise between size and quality, try different settings.

    Note: To change the object’s compression setting, use the Bitmap Properties dialog box to set the bitmap export quality per object. The default compression option in the Bitmap Properties dialog box applies the Publish Settings JPEG Quality option.
    Progressive

    Show Progressive JPEG images incrementally in a web browser, which makes images appear faster when loading with a slow network connection. Similar to interlacing in GIF and PNG images.
  4. Click OK.
