About WatermarkNinja

WatermarkNinja is a free tool for removing the TikTok watermark, the bouncing logo and @username, from your own photos and screenshots. You paint over the mark, and AI inpainting rebuilds the background behind it.

How it works

The removal runs on the LaMa inpainting model, the same engine that powers our sister tool BGNinja. When you click remove, your photo and the mask you painted are sent to that engine, the background is reconstructed, and the result comes straight back to your browser.

Privacy first

We do not keep your images. They are processed and discarded immediately, and there is no account to create. See our privacy policy for the detail.

Part of Shinobi Tools

WatermarkNinja is one of the Shinobi Tools, a small family of free, single-purpose utilities: background removal, photo restoration, metadata stripping, stem splitting, and more. Each does one job well, with no sign-up and no upsell.
