Image Watermark — free online tool

Freelancers and stock contributors add a semi-transparent text watermark with position and colour controls before sharing proofs.

When to use Image Watermark

Mark proof images for clients so drafts are harder to reuse without credit.

Good for email attachments, CMS uploads, and faster page loads without installing desktop software.

What Image Watermark does not do

Text overlay only—no logo PNG watermark, no EXIF copyright injection, no DRM.

How to use Image Watermark

  1. Upload the image you want to mark on Image Watermark.
  2. Type watermark text, pick position, opacity, and colour from the controls.
  3. Apply watermark and review the composite preview.
  4. Download the stamped image before sharing proofs with clients.

Practical tips

  • Keep watermark opacity around 30–50% so it deters copying without ruining the proof.
  • Place the mark over busy detail, not plain sky, where it is easy to crop out.
  • Use a contrasting colour—white on dark images, dark on light—so it stays visible.

Example

Overlay “PROOF — client name” at 40% opacity bottom-right on draft photos.

Try a smaller file, fewer pasted characters, or an updated browser. Extensions that block scripts or downloads sometimes interfere—test in a private window if results never appear.
