Image Watermark Tool Guide
Reference for adding text and logo watermarks to screenshots, product images, mockups, social images, and review drafts in the browser.
Quick answer
Use the Image Watermark Tool to place a text label or logo mark on a browser-readable image before sharing, reviewing, or publishing it. Watermarking is a visible context marker; it is not a technical protection system.
What this tool does
The tool loads an image, places a text or logo watermark over it, lets you adjust opacity, size, rotation, and position, then exports a watermarked image.
Supported input
- JPG, PNG, and WebP images that the browser can decode
- Screenshots
- Product photos
- Mockups and review drafts
- Extracted video thumbnails
Output
- Downloadable watermarked image
- Visible text or logo overlay
- Export based on the current browser rendering path
Data handling and processing behavior
Processing is handled in the browser for this tool based on the current public implementation. Avoid using sensitive images unless you have reviewed the implementation and your own sharing requirements.
Step-by-step use
- Choose a source image.
- Pick text watermark or logo watermark.
- Adjust opacity, size, rotation, and placement.
- Preview the result at the final display size.
- Export and compress the watermarked image if needed.
Examples
Client preview
Add a semi-transparent "Draft" label to a mockup before sharing it in a review thread.
Social asset
Place a small logo or handle in a corner before posting an image that may be reposted.
Video thumbnail
Extract a cover frame, crop it, then add a subtle brand mark before publishing.
Assumptions and limits
- A watermark can be cropped or edited out.
- Very low opacity may disappear after compression.
- Canvas export may change metadata or color-profile details.
- Logos with transparent backgrounds work best as PNG or WebP.
Common errors
Watermark too small
Small marks may vanish on mobile feeds or after compression.
Watermark too strong
A large opaque mark can make product details or text unreadable.
Adding the watermark before cropping
Crop first when the final aspect ratio is known, then place the watermark.
