A free, private tool that stamps a text and/or logo watermark across one or hundreds of images at once — useful for protecting photos, branding product shots or marking proofs. Every image is processed on a canvas in your browser, so nothing is ever uploaded, and it keeps working offline after the first load.
How to use Image watermark & batch brander
- Add your images — Drop JPG, PNG or WebP files onto the panel — or click to choose. Add as many as you like; each appears as a thumbnail you can select to preview.
- Set up the watermark — Type your text watermark and adjust its size, opacity, angle and colour, with an optional drop shadow or tiled repeat. You can also switch on a logo watermark and pick a logo image.
- Choose placement and output — Pick one of nine positions, set the margin, and choose the export format (JPEG, PNG or WebP) and quality. The live preview updates as you change anything.
- Download — Double-click any thumbnail to download just that branded image on its own, or use the ZIP archive action in the header to brand and download every image as a single zip.
Frequently asked questions
Are my images uploaded to a server?
No. Every image is processed on a canvas inside your browser, so the originals and the branded versions never leave your device.
Can I add both text and a logo?
Yes. Turn on the text watermark, the logo watermark, or both. Each has its own scale and opacity controls so you can balance them.
What is the tile option for?
Tiling repeats the text watermark diagonally across the whole picture instead of placing it in one corner — handy for proofs or preventing easy cropping.
Which formats can I export?
You can save as JPEG, PNG or WebP, with an adjustable quality setting for JPEG and WebP.
Will the original resolution change?
No. Each image is watermarked at its full original pixel size, so the output keeps the same dimensions as the file you added.
Tips
- Keep the drop shadow on when stamping over busy or pale photos so the text stays readable.
- Use a high-opacity logo in a corner for branding, or a low-opacity tiled text for proofs.
- Set the placement and margin once, then download the whole batch as a zip to brand everything consistently.
- Export as PNG when your logo needs a transparent background; use JPEG to keep file sizes small.
