Questions
How much smaller will my PDF get?
Scanned documents and PDFs full of photos often shrink by 50–90%. PDFs that are mostly typed text are already small; if our version comes out larger, the tool tells you to keep the original.
Will I still be able to select text?
No. This method turns pages into images, so text can't be selected or searched afterwards. Keep the original if you need that.
Which level should I use?
Recommended suits email and most upload forms. Use Light for documents you'll print, and Strong when you must get under a strict size limit.
Is my PDF uploaded to a server?
No. The tool runs in your browser and works on your PDF directly on your device. Nothing is sent to us or anyone else, which is why it also keeps working if your connection drops after the page loads.
