Frequently asked questions
Is my PDF uploaded?
No — your file is processed entirely in your browser and is never uploaded to a server, so even sensitive files stay private.
Is it free?
Yes — it is free with no sign-up, no watermark and no account-based quota. Your browser, device memory and the bench's stated file limits still determine how much it can process at once.
Will compression preserve selectable text?
Pages are rasterized into JPEG images before the new PDF is built, so selectable text, links and form fields are not preserved.
