### 5.5.4 JPEG-Images In The SWF- And The PDF-Format

The SWF- and the PDF-format allow to embed JPEG-images. PhotoLine fully supports this feature. It uses the following rules:

- If the image compression setup in the file options is different to JPEG, existing JPEG-data will be saved.
- If the image compression is JPEG, the existing JPEG-data will only be saved if the are smaller than those created using the entered JPEG-compression.

By using this approach the size of PDF- and SWF-files can be controlled in a very detailed way by manually JPEG-compressing some images.
