Frequently asked questions
Is it safe to watermark PDFs on this site?
Yes — your file never leaves your device. VitePDF runs entirely in your browser tab; nothing is sent to a server.
Can I control how visible the watermark is?
Yes — the opacity slider lets you make it subtle or bold, and the live preview shows the result before you download.
Is there a file size or page limit?
Files up to 70 MB are free — Premium removes that limit entirely.
