Frequently asked questions
Is my PDF uploaded to a server?
No. The watermark is added by your browser, on your device. Nothing is sent to us or to anyone else.
Can I write the watermark in any language?
Yes. Latin text uses the standard PDF fonts; other scripts, such as Arabic, Chinese or Cyrillic, are drawn with your device’s fonts at high resolution.
Can someone remove the watermark?
It becomes part of each page, but a determined person with editing software could still remove it. A watermark discourages copying; it doesn’t make it impossible.
Can I use my logo?
Yes. Choose Image and pick a PNG, JPG or WebP file. A PNG with a transparent background gives the cleanest result.
Can I mark only some pages?
Yes. Type the pages in the Pages field, for example 1 for the cover only, or 2-10.
