File privacy and limits
This tool is designed to process files in your browser where possible. That means your selected files are handled on your device instead of being uploaded to a We Love Free PDF server.
Very large PDFs can still be slow because your browser has to do the work. For a smoother experience, use smaller files when possible and always check the downloaded result before sharing it.
How to use Compress PDF
- Upload your PDF file.
- Choose a compression level.
- Click Compress PDF and compare the new file size.

Compress PDF FAQ
Why did my PDF not become much smaller?
Some PDFs are already optimized. Try scanned PDF compression for image-heavy files, but remember it turns pages into images.
Will compression damage my PDF?
Safe optimization keeps the PDF structure. Scanned PDF compression creates image pages, so always check important files after download.
Can I compress PDF for email?
Yes. This tool is designed to help make PDFs easier to email or upload.
