About the Add Watermark tool
Protect your photography and designs with a text watermark — a single corner mark or a diagonal tile across the whole image. Adjust opacity so it protects without distracting.
Like every Pixveil tool, the Add Watermark runs 100% in your browser. Your image is opened with the HTML5 File API, processed on an invisible canvas on your own device, and saved straight back to your downloads folder — it is never uploaded, stored, or seen by anyone. That's what makes Pixveil the best free image tool suite for anything private: family photos, ID documents, unreleased designs, or client work under NDA.
How to use it
Drop an image on the upload area (or click it to browse), adjust the options and watch the live preview update, then hit Download. There are no accounts, no queues, and no limits — use it as many times as you like, free forever.
