Questions
Is it really free, with no sign-up?
Yes, completely. There's no sign-up, no login and no daily limit: just open the page and start. It works in your browser on any computer, phone or tablet with nothing to install, and your files are never uploaded — everything happens on your device.
Why didn’t my PDF get much smaller?
PDFs made of text are already small. The big savings come from photos and scanned pages.
Are my PDFs uploaded?
No. They’re processed in your browser, on your device, and never sent anywhere.
