透かし — frequently asked questions

Can I add an image watermark instead of text?+

Yes — use the separate Image Watermark tool for a logo or photo instead of text.

Will the watermark appear on every page?+

Yes, it's applied uniformly across the whole document.

Do you upload my files to a server?+

No — every tool here processes your files entirely on your device, and nothing is uploaded to a server. The AI tools that used to send extracted text to a server are currently disabled.

Is there a file size limit?+

There's no artificial limit we impose, but since processing happens in your browser, very large files (500+ MB or 1,000+ pages) are limited by your device's memory rather than by us.
