Batch watermark images
Type your watermark text, choose a position and opacity, and stamp a whole batch at once. Tiled mode covers the frame so the mark is hard to crop away.
Upload and process
Runs locallyHow to use it
- Enter the watermark text — your brand name or domain works well.
- Choose one of nine positions, or switch on tiling to cover the image.
- Adjust opacity, size and colour so the mark is visible but not distracting.
- Upload your images, as many as you need.
- Click run, then download individually or as a single ZIP.
When this tool helps
A watermark is the cheapest protection against people re-uploading your work as their own. Doing one image by hand is fine, but a set of thirty is miserable. Configure once, apply to the batch, and the output keeps the original dimensions. Tiled coverage is worth calling out: a mark in one corner is a single crop away from being gone, while a tiled watermark makes removal genuinely labour-intensive.
FAQ
Can a watermark be removed?
Removing one always degrades the image, but it is not impossible — especially with very light or corner-placed marks. Keep opacity reasonable and prefer tiling for valuable work.
Do you support image or logo watermarks?
This version handles text watermarks. Image overlays are on the roadmap — tell me if you need them and they move up the list.
What size should the watermark be?
Size is a percentage of image width, so it scales automatically across different resolutions. Around 5% suits a discreet corner mark, 10% or more suits tiling.
Does it change the image dimensions?
No. The output matches the original size with the watermark composited on top.
Are my images uploaded?
No. Compositing happens in your browser and files stay on your device.
