Brand product photos with your shop logo before uploading to marketplaces. Deters image theft by competitors.
Bloggers and content creators

Designers sharing previews
Send client mockups with a PROOF or DRAFT watermark so they cannot be used before final payment.

Preview images with a tiled watermark make it impossible to use the image without licensing. Full-coverage tile is the industry standard.
Businesses protecting documents
Add CONFIDENTIAL watermarks to sensitive internal images and screenshots before sharing.
No uploads, 100% private
Your images never leave your device. All processing uses the browser Canvas API. Competitors upload your photos to their servers.

Apply the same settings to an entire batch and download as a ZIP. Most free tools only support one image at a time.
Tile repeat for full coverage
The repeating grid watermark is the strongest protection option. Used by stock photo agencies worldwide.
No paywalls or feature limits
Batch, tiling, logo upload, rotation and opacity are all free. Competitors charge for batch and logo features.

Yes. Upload up to 20 images at once. Configure your watermark settings once, click Apply to all images, and download them individually or as a ZIP archive. All images are processed sequentially in your browser.
40 to 60% opacity is the professional standard for visible but unobtrusive watermarks. This makes the watermark clearly visible while still letting the underlying image show through naturally.
Tile mode repeats your watermark in a grid pattern across the entire image. This provides the strongest protection because it is much harder to remove than a single-corner watermark. It is recommended for stock photography and high-value content.
No. All watermark processing happens locally in your browser using the HTML5 Canvas API. Your images never leave your device. You can disconnect from the internet after loading the page and the tool will still work.
PNG with a transparent background works best for logo watermarks. Transparency means only your logo appears on the image, without a white or colored rectangle behind it. Most logo design tools and brand kits provide transparent PNG versions.
Yes. Use the rotation slider and set it to 45 or -45 degrees for a diagonal watermark. Diagonal watermarks are popular because they are harder to crop out than corner watermarks.
