Sample workflow: choose a JPEG, PNG, WebP, or GIF on this device, then Process.

Stamp a short text overlay on a photo in this tab — a name or ‘proof’ in a corner. It is not an invisible watermark, not a PDF confidential stamp, and not a rights-management system.

A proof JPEG needs your name in the corner before you send it. That is this page: text overlay, opacity, a corner — in the current tab.

Watermark PDF is the document sibling. Sign PDF is a signature stamp on pages.

How to use it

  1. Drop a JPEG, PNG, or WebP.
  2. Type the label, pick a corner and opacity. Process in this tab.
  3. Compress afterward if email still complains.

Typical ceiling is about 32 MB.

Honest limits

  • Not steganography.
  • Not a lawyer’s copyright filing.
  • Tiny type on a 12 MP photo disappears when someone resizes; keep it large.

This is a local utility, not a stock-photo platform.

FAQ

Can I watermark a PDF?

Use watermark PDF. This page is still images.

Will this stop people stealing the photo?

No. They can crop or screenshot. A corner label is a reminder, not DRM.

Can I use a logo PNG?

This build overlays text. A logo composite is not guaranteed.

Does the overlay flatten EXIF?

You get a new raster. Strip EXIF if privacy is also the job.

Is the photo uploaded?

No. Typical ceiling is about 32 MB.
