What is this tool?
Add Watermark lets you place a text watermark on an image directly in your browser. Watermarks are useful for drafts, previews, sample photos, product images, teaching materials, client proofs, and social posts where you want to show ownership, status, or usage limits before sharing the final version.
A good watermark should be visible without ruining the image. Short text, moderate opacity, and careful placement usually work better than large distracting marks. For product listings or portfolio previews, keep the watermark consistent so the image still looks professional.
This tool creates a new exported copy with the watermark applied. Keep your original image unmarked as the master file, especially if you may need to create clean versions, alternate sizes, or final client exports later.

Limitations to know
- Browser canvas export can slightly change compression, metadata, color handling, or file size compared with the source.
- Advanced professional editing features such as layered design, raw photo editing, and AI restoration are outside this tool's current scope.
- Very large images can require more device memory and may process more slowly on phones or older computers.
- The exported file is a new browser-generated copy, so you should keep your original file if you may need to edit it again.

Frequently Asked Questions
Can I remove a watermark after downloading?+
The downloaded image has the watermark applied to its pixels. Keep the original clean file if you may need an unwatermarked version.
What should I write as a watermark?+
Use a short brand name, website, copyright notice, draft label, or client preview label.
Where should I place a watermark?+
Choose a place that is visible but does not hide important details. Corners or low-opacity centered text are common choices.
Does watermarking protect images completely?+
No watermark is perfect protection, but it can discourage casual reuse and make preview images easier to identify.
