Frequently Asked Questions
Is my PDF uploaded to any server?
No. The PDF compressor works entirely in your browser using pdf-lib. Your file never leaves your device and is never uploaded to any server.
How much can I reduce PDF size?
Depends on the PDF content. PDFs with many images can be reduced by 40-80%. Text-only PDFs have minimal reduction since text is already compact.
Will compression reduce PDF quality?
Low compression has minimal quality impact. Medium compression is good for most documents. High compression reduces image quality noticeably but keeps text sharp.
What is the maximum PDF size I can compress?
There is no hard limit, but very large PDFs (100MB+) may take longer to process in the browser. For best performance, use PDFs under 50MB.
Can I compress encrypted or password-protected PDFs?
Encrypted PDFs cannot be compressed. Remove the password protection first, then compress.
Why is my compressed PDF the same size?
If your PDF contains only text (no images), compression will have minimal effect. This tool primarily compresses embedded images within PDFs.
Is this tool free to use?
Yes, completely free. No registration, no login, no watermarks, no limits.
