Frequently Asked Questions

Is the PDF compressor free?

Yes, completely free. No account, no watermarks, and no limits on the number of files you compress.

Will compression reduce the quality of my PDF?

Our Standard compression reduces file size with minimal visible quality loss. High compression achieves the smallest file size but may slightly reduce image sharpness in image-heavy PDFs.

How much can I reduce a PDF file size?

Results vary by content. PDFs with large images typically compress 50–80%. Text-only PDFs may see smaller reductions since text is already compact.

Is it safe to upload my PDF?

Yes. Files are transferred over HTTPS and permanently deleted from our servers immediately after download. We never read or share your documents.
