Frequently asked questions
Can I use my logo as a watermark?
Yes. Switch to an image watermark and upload a PNG or JPG - it is placed on every page.
Will the watermark cover my text?
Lower the opacity so the watermark sits lightly behind your content, or move it to a corner.
Is this tool free?
Yes - it is completely free, with no account, no limits, and no watermarks added to your files. Every PDF tool on File-Extension works the same way.
