About this tool
Add a watermark to an image — text or an uploaded logo, with adjustable opacity, size, and position. Useful for protecting photos before sharing online, branding marketing assets, or marking images as proofs or drafts. The watermark is rendered into the image, not as a separate layer.
When to use it
- Protecting photos from unauthorised reuse before posting online
- Adding a brand logo to product or marketing photos
- Marking image proofs as `DRAFT` or `SAMPLE` before client review
- Stamping ownership info into photos for a portfolio
- Adding date or version markers to photos for record-keeping
What to expect
The watermark is permanently rendered into the image — it travels with the file and can't be peeled off. Use opacity below 100% so the watermark is visible without obscuring the image. PNG logos with transparent backgrounds give the cleanest results.
Frequently asked questions
Can the watermark be removed by the recipient?
Not without specialised image-editing skills. The watermark is part of the rendered pixels. A determined editor could try to clone it out, but for casual reuse prevention it's effective.
What size should my logo file be?
A transparent PNG sized close to its final on-image size. For most uses, 200–600 pixels on the longest edge works well. The tool can scale the logo down or up, but starting close to the target size avoids quality loss.
Can I watermark many images at once?
The single-image watermark tool is for one image. For batch watermarking, run the tool repeatedly or use a script — bulk watermarking with consistent positioning is best handled with a dedicated workflow.
