Add Watermark to Image

A real watermark editor that runs free and entirely in your browser. Add text or logo stamps to one large preview, drag each into place, resize it from the corners, rotate it with a drag grip, and set its opacity from a floating toolbar — or tile one across the whole image. Stack as many stamps as you need; the preview runs the exact same drawing math as the full-resolution export.

How to watermark an image with Allypdf

  1. Drop in the photo — it stays on your device.
  2. Add a text or logo watermark from the side panel: type your text and choose a color, or pick a logo (a transparent PNG keeps its transparency).
  3. Drag it into place on the preview, resize from the corners, rotate with the grip beneath it, and set opacity in its toolbar — duplicate it for more stamps, or tile it across the image.
  4. Click Add Watermark — the stamps are drawn once at full resolution and the image downloads directly.

Why "no upload" matters here

Photographers watermark the photos they most want to protect — client previews, unreleased work, paid content. Uploading the clean originals to a watermarking server means a stranger holds the unprotected copies. Allypdf draws the watermark on a canvas in your own browser tab: the photo and the logo never leave your device, and the export has EXIF metadata (GPS position, camera details) stripped.

Common uses

  • Add a © copyright line to photos before posting them publicly.
  • Stamp your studio logo on client proofs so previews can circulate safely.
  • Tile a semi-transparent watermark across product shots competitors like to steal.
  • Mark screenshots or document scans as 'CONFIDENTIAL' or 'DRAFT' before sharing.

Frequently asked questions

How do I add a watermark to a photo for free?

Open Allypdf's Watermark Image tool, drop in the photo, type text or add a logo, place it with the real-time preview, and click Add Watermark — the stamped photo downloads immediately. Free, no account, and the only watermark is yours.

Does the preview match the download?

Yes — the editor runs the exact same watermark-drawing function as the export, just on a smaller render. Every size and position is a fraction of the image, so the placement is identical at full resolution.

Can I put several watermarks on one photo?

Yes — stack as many text and logo stamps as you like. Duplicate the selected stamp from its floating toolbar and drag the copy anywhere; each keeps its own size, rotation, and opacity.

Can a watermark be removed by someone else?

Any visible watermark can be attacked with enough editing effort, and a corner stamp can simply be cropped off — no tool should pretend otherwise. Tiling repeats the watermark across the entire image, which defeats cropping and makes retouching tedious.

Are my photos or my logo uploaded?

No. Both are decoded and drawn on a canvas in your browser, and the export has EXIF metadata stripped.
