Compress PDF details
Compress PDF is deliberately conservative about claims: it works best when PDF pages are image-heavy and size reduction is worth rasterization.
File handling
- Input: One PDF file.
- Output: A rebuilt PDF optimized for image-heavy documents.
- Privacy: Processing runs in your browser for this live tool. PDFde does not upload the selected document contents to its servers.
Best for
- Scanned PDFs, photo PDFs, and image-heavy forms
- Reducing file size before email or portal upload
- Choosing a quality level before rebuilding
Know before using
- Text-heavy PDFs may not shrink
- Pages are rebuilt as JPEG images, so selectable text is removed
- Fine print can degrade at aggressive compression settings
