Frequently asked questions

How do I reduce the size of a PDF?

Pick a compression level and click Compress PDF. Balanced is a good starting point. If the result is still too large, run it again with Strong.

Will compression lower quality?

Yes, to a degree. This tool re-renders each page as an image, so Strong gives the smallest file and Light keeps the most detail.

Can I still select text after compressing?

No. Because pages become images, the text in the compressed file cannot be selected or searched. Keep your original for that.

Is it free and private?

Yes. It is free, needs no sign-up, and runs in your browser.
