Frequently Asked Questions

Is PDF compression free?

Yes, completely free with no limits, no sign-up, and no watermarks on the compressed file.

How much can I reduce the file size?

It depends on the content. PDFs with many high-resolution images can be reduced significantly. Text-only PDFs may only reduce by a smaller amount since text already compresses efficiently.

Will compression reduce quality?

Low compression makes no visible quality difference. Medium is balanced for screen viewing. High compression gives maximum size reduction.

Is there a file size limit?

No. You can upload a PDF of any size.

Are my files kept private?

Yes. All uploaded and compressed files are permanently deleted from our server within 1 hour.

Why is my compressed file the same size?

Some PDFs are already well-optimised. When the compressed version is not smaller, we serve the original file unchanged.
