Image watermarks, explained
What types of watermarks can I add?
Two kinds. A text watermark with your own text, seven fonts, adjustable size (8–200px), any colour, optional bold, an outline and a drop shadow; or an image / logo watermark where you overlay your own PNG, JPG or WebP at a size you choose. Both support opacity, rotation, nine positions, free dragging and full-image tiling.
Does it upload my images to a server?
No. Everything runs 100% client-side in your browser using the HTML Canvas API. Your photos and your logo are never uploaded, never stored and never leave your device, which makes the tool both private and fast — ideal for personal photos, client work and confidential images.
Can I use my own logo as a watermark?
Yes. Switch to the Image tab in the watermark-type selector and upload any PNG, JPG or WebP. Transparent PNG logos work best because the see-through areas stay see-through over your photo. Use the size and opacity sliders to make it as subtle or prominent as you like.
Can I tile the watermark across the whole image?
Yes. Tick Repeat across entire image under Tiling to repeat the watermark in a grid across the entire photo, with an adjustable spacing control; combine it with rotation for diagonal marks. A tiled, semi-transparent watermark is much harder to crop or clone out, so it's the best option for protecting portfolios, proofs and stock photos.
What position and rotation options are there?
Nine anchor positions — the corners, edges and centre — or drag the watermark anywhere on the preview, plus a rotation slider from −180° to +180° for diagonal or angled marks. Opacity runs from 1% (barely visible) to 100% (solid), so you can balance protection against keeping the photo readable.
What export formats and quality are supported?
Export as PNG (lossless, keeps transparency) or JPEG with a quality slider from 10% to 100% for smaller files. The download is the full-resolution image with your watermark baked in — there is no extra app watermark added to the output.
Can I watermark several images at once?
Yes. Drop or choose several images at once, or add more with + Add images. They appear as thumbnails, and Export all (ZIP) renders every image with the same watermark settings and downloads them as one ZIP file. A dragged position is kept relative to each image's size.

Add a watermark to your photos online
This free image watermark tool lets you stamp a text caption or a logo onto any photo, right in your browser. Drop in a JPG, PNG or WebP, choose a text or image watermark, fine-tune the position, size, opacity, rotation and tiling, and download the result as a PNG or JPEG. There is nothing to install and nothing to upload — your images are processed entirely on your own device, so even private or client photos stay private.
How to watermark an image
- Add your photo. Drag an image onto the drop zone or click to choose a file (JPG, PNG or WebP).
- Pick a watermark type. Choose Text to type a caption or copyright line, or Image to upload your logo.
- Style it. Set the font, size, colour and bold for text, or the scale for a logo, then adjust opacity and rotation.
- Place it. Pick one of nine positions, or switch on tiling to repeat the mark across the whole photo.
- Export. Choose PNG or JPEG (with a quality slider) and download your watermarked image.
Why watermark your images
Watermarking deters unauthorised reuse and keeps your name or brand attached to your work as it travels around the web. Photographers and designers protect proofs and portfolio shots; online sellers and creators brand product photos and social posts; businesses mark up reports, screenshots and slides; and anyone can add a simple copyright line before sharing. A subtle, tiled, semi-transparent watermark offers the best protection because it is difficult to crop or edit out without damaging the picture.
Private by design
Unlike many online watermark services, this tool never sends your pictures anywhere. All processing happens locally with the HTML Canvas API, so there are no uploads and no servers.
