Frequently Asked Questions
Does this PDF compressor upload my file?
No. Compression runs entirely in your browser using WebAssembly. Your file never leaves your device and is never sent to any server.
Why do other tools upload my PDF to compress it?
Most PDF tools like Smallpdf and ILovePDF process files on their servers — that is how they justify charging $111-$180/year. We built a browser-based alternative that needs no server at all.
Is there a file size limit?
No. Since processing is local, limits depend only on your browser and device memory — not on our servers.
Is this really free forever?
Yes. No trial, no subscription, no credit card. Free forever.
Free forever. Not free for 14 days.
