Question 1

How do I compress a PDF?

Accepted Answer

Upload your PDF, pick a compression level, and download the smaller file — no settings or software needed.

Question 2

How much smaller will my PDF get?

Accepted Answer

It depends on the file. Image-heavy and scanned PDFs shrink the most; text-only PDFs are already small so they compress less.

Question 3

Will compressing reduce the quality?

Accepted Answer

Higher compression trades some image quality for a smaller size. Use the balanced level to keep documents sharp while still saving space.

Question 4

Is it free and private?

Accepted Answer

Yes. Compression is free with no sign-up and happens entirely in your browser, so your file is never uploaded.
