About this tool
Watermark Image adds a diagonal, tiled text pattern across each picture, the kind of mark stock sites use, so previews can be shared without handing over the clean file. Pick the text, the colour and the opacity; the font size scales with the image, and every file keeps its format. Up to 25 images are processed in your browser and downloaded individually or as a .zip.
Remove metadata that reveals where a photo was taken with the Image EXIF Remover.
How to use it — quick steps
- 01
Add the images
Drop PNG, JPEG or WebP files on the dashed area or choose them from your device, up to 25 images per run.
- 02
Write the watermark
Type the text, for example your name or site, pick a colour and set the opacity (30% by default).
- 03
Press "Add watermark"
The text is repeated diagonally across every image; download the files one by one or all as a .zip.
Key features of this tool
Hard to remove
A rotated, tiled pattern across the whole picture cannot be cropped out like a corner logo.
Scales with the image
The text size follows the image dimensions, so small thumbnails and large photos get a proportional mark.
Files never leave your device
Reading, compressing and rewriting happen in your browser with the File API; nothing is uploaded to IPVoid.
Frequently asked questions
Which opacity should I use?
20-35% protects the image while keeping it readable; use higher values for previews that must not be reused at all.
Can I use a logo instead of text?
This tool applies text only; a logo overlay is on the roadmap.
Does it keep the original quality?
The image is re-encoded in its own format (JPEG and WebP at quality 92, PNG lossless); the watermark is part of the pixels.
Are my files or data uploaded?
No. The tool is plain JavaScript that runs in your browser; the files or data you provide here are never uploaded to our servers.
