Frequently asked questions

How much smaller will my PDF get?

It depends on the source. Scanned or image-heavy PDFs typically shrink by 50–90%. PDFs that are already highly optimized may not shrink much — try the High compression preset for the smallest result.

Will text stay selectable after compression?

No. Real compression rasterizes each page into an image, so text in the output is part of the picture and cannot be selected or searched. Use OCR afterwards if you need selectable text back.

Is there a file size limit?

There is no hard limit set by the site. Because compression runs in your browser, practical limits depend on your device's RAM — most desktops handle 200 MB+ PDFs comfortably.

Are my files uploaded to a server?

No. Files are processed directly in your browser using JavaScript and WebAssembly. Nothing is uploaded to our servers, so your documents never leave your device.

Does it work on mobile?

Yes. The tools run in any modern browser on desktop, tablet, or mobile (Chrome, Edge, Safari, Firefox). Very large files may be slower on low-end phones.
