Image Watermark — free online tool
Freelancers and stock contributors add a semi-transparent text watermark with position and colour controls before sharing proofs.
Good for email attachments, CMS uploads, and faster page loads without installing desktop software.
How to use Image Watermark
- Upload the image you want to mark on Image Watermark.
- Type watermark text, pick position, opacity, and colour from the controls.
- Apply watermark and review the composite preview.
- 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.
Limitations
Image Watermark depends on what your browser can decode (HEIC, SVG, animated GIF, etc.). Output quality and colour profile may shift slightly compared with desktop Photoshop.
