Your images never leave your device
There's no backend server. Your images are processed directly in the browser, and the results only exist in your browser's memory. Close the tab and everything's gone. We can't see your images, and we have no way to.
No sign-up, no login
No accounts, no email collection, no tracking. Open the page, use it, close it. Nobody's going to send you marketing emails.

Features
Text watermark
Custom text with adjustable font size (12-200px), color, opacity, and rotation. Supports single placement or tiled across the whole image.
Watermark removal
Select the watermark area and the tool fills it with surrounding pixels. Works best on simple or solid-color backgrounds.
Batch processing
Select multiple images (2-50), apply the same watermark settings to all, download as a ZIP. Saves you from doing them one by one.
Multiple export formats
Download processed images as PNG, JPG, or WebP. For JPG you can also adjust compression quality (1-100).
Live preview
When adding watermarks, changes show up instantly. No need to keep hitting "process" to see what it looks like.
Works on mobile
Responsive layout that works on phones, tablets, and desktops. Large images will process faster on a computer though.
FAQ
Are my images really not uploaded?
Really. Open your browser's dev tools (F12), go to the Network tab, and process an image. You'll see zero requests going out.
What if watermark removal doesn't look good?
The removal uses pixel-fill algorithms that work best on solid or simple-texture backgrounds. If the watermark covers complex patterns (like faces), results won't be perfect. Try selecting smaller areas or making multiple passes.
What image formats are supported?
PNG, JPG (JPEG), and WebP. Max 20MB per image. If your image is larger, compress it with another tool first.
Processing is slow?
Speed depends on your device and image size. Large images (4000×3000+ pixels) might take a few seconds on mobile. If it's stuck, try on a computer or resize the image first.
