Frequently Asked Questions

Can I use my own custom watermark text?

Yes. Type any text you want, choose from 4 colors, and adjust opacity and rotation to taste. You can also upload your own logo or image instead of text.

Can I choose exactly where the watermark appears?

Yes — pick from 9 positions (all four corners, edges, or dead center), with a live preview rendered on an actual page of your document, so you can see roughly how it'll really look before you apply it.

Can I add more than one watermark to the same document?

Yes — configure one watermark, click "Add Another Watermark," and repeat as many times as you like. All of them get stamped together in a single pass, each with its own text or image, color, position, and rotation.

Will the watermark cover up important content?

The watermark is applied at reduced opacity and sized to sit across the page without fully obscuring the original content underneath.

Does this work on multiple PDFs at once?

Yes — select as many PDFs as you like and they'll all be stamped in one batch, downloaded one after another.

Is my file uploaded anywhere?

No. Watermarking happens entirely inside your browser using local JavaScript. Nothing is ever sent to a server.

Is there a cost or file limit?

No. It's free, with no daily limit and no artificial file size cap.
