Add your file

Drag & drop, browse files, or press Ctrl+V to paste from the clipboard where supported.

Frequently Asked Questions

Can I use a logo PNG?

Yes. Transparent PNG logos overlay cleanly.

Tile the watermark?

Enable Repeat to diagonal-tile the mark across the whole photo.

Can someone remove it?

A watermark deters casual reuse; it is not encryption.

Is Watermark completely free to use?

Yes. Watermark on Omnipus is free to use with no subscription paywall for the tool itself.

Are my files or data uploaded to any servers?

No. Watermark processes your input locally in this browser tab. Your files and text are not sent to Omnipus. Some tools download an engine or model file the first time you use them; that is a download, not an upload.

Does Omnipus add watermarks to exported files?

No. Omnipus does not stamp a site watermark onto files you export from Watermark.

Can I use Watermark on my mobile phone?

Yes. Omnipus has touch-friendly controls and can be installed as an app. On Android you can also share files or links into tools from other apps.
