Drop PDF files or whole folders here
Up to 100 MB per file. Other files in a folder are skipped.
How to compress PDFs in bulk
- Drop in your PDFs, or press Choose a folder.
- Pick how strongly to compress. Recommended suits most files.
- Press Compress PDFs, then download each file or everything as one ZIP that keeps your folder layout.
🔒 PDFs are compressed on our server, two at a time, over an encrypted connection. Each file is deleted as soon as it has been compressed. Nothing is kept or looked at.
What to expect
- PDFs full of photos or scans shrink the most, often by 50–90%.
- Text stays sharp and can still be selected, searched and copied.
- A PDF that is already as small as it can be is handed back unchanged, so you never get a bigger file.
- Password-protected PDFs must be unlocked first.
