Free Image Watermark
Add a text or logo watermark to one or many photos — position, opacity, rotation, and diagonal tiling. Batch export, no upload, no extra branding.
Many watermark sites upload your photos to their server — here they're marked on your device, in batches.
🔒 Your images are watermarked on your device and never uploaded.
How It Works
Stamps a text or logo watermark onto your images using the browser's Canvas engine. Unlike many free tools, it never adds its own branding, never caps batch size, and never uploads your photos.
- 1Drop your imagesEach image is decoded in your browser, respecting EXIF orientation so phone photos stay upright. Add one or many.
- 2Design the watermarkType text (with color, size, opacity, rotation) or upload a logo PNG. Choose a corner/center position, or tile it diagonally across the whole image.
- 3ExportThe watermark is composited at full resolution onto each image and saved as JPG, PNG, or WebP — a single file, or a ZIP for batches.
Everything is drawn on a local <canvas>. Your images never leave your device, and no extra watermark or branding is added beyond the one you design.
