Frequently asked questions
Is this PDF tool free?
Yes. It is completely free. No sign-up, no credit card, and no paid trial.
Does my file leave my browser?
No. Your file never leaves your browser.
Will the text still be selectable?
Yes, on High quality and Balanced. Smallest file turns each page into an image, so the text looks the same but can no longer be selected or searched.
Why did the file barely shrink?
PDFs that are mostly text are already small. The big savings come from photos and scans. Use Smallest file when the other levels do not help.
