Question 1

Is PDF Compress free?

Accepted Answer

Yes. You can use this tool online at no cost.

Question 2

Do you upload my PDF?

Accepted Answer

Yes. This tool runs in your browser. Files are not uploaded to our servers.

Question 3

What is the file size limit?

Accepted Answer

For reliable mobile processing we cap uploads at 40 MB and about 80 pages. Very large files may fail on phones due to memory limits.

Question 4

Does it work on mobile?

Accepted Answer

Yes. The layout is mobile-first. Very large PDFs still work best on desktop.

Question 5

Will quality stay perfect?

Accepted Answer

No. This tool shrinks PDFs by redrawing pages. Text-only files may not shrink much. Image-heavy scans usually get smaller with some quality loss.
