What is Watermark?
Add a text or logo watermark with placement presets, opacity, size, rotation, and optional tiling. The preview updates live and the download uses the full-resolution source.
Trust and privacy are built into the workflow. No files leave your device during processing, and there is no account setup required. That makes Watermark suitable for personal photos, client assets, product images, and everyday creative work.
How to use Watermark
- Upload or drag your image into the tool above.
- Adjust the editing controls until the live preview looks right.
- Choose an output format (and quality when relevant).
- Download the edited image — processing stays on your device.
Tip: preview at a comfortable zoom, then export once you are happy — repeating lossy saves can add compression artifacts.
Key benefits of Watermark
- Use tiling for subtle all-over protection
- Lower opacity keeps subjects readable
- PNG logos with transparency work best for logo mode
- Export PNG/WebP when the base image has transparency
Privacy note: no files leave your device. All edit steps run locally in your browser.
