Watermark your photos — without uploading them

What is this page?

This is the real Batch Watermark Tool — the same tool Untracked sells as a download — running free, right here in your browser. Your files are processed entirely on your own device: nothing is uploaded, no account is needed, and the page makes no network requests after it loads. You can verify that yourself: load the page, open your browser's network inspector, or even disconnect from the internet and keep using it.

Free page vs. the €9 download

• Here (free): unlimited single files — one at a time, as many as you like, forever. Counted only in your own browser (localStorage): no cookies, no analytics, nothing that identifies you.
• The download (€9, once): batch/folder processing, ZIP export, and the tool as a single HTML file that runs offline forever on any computer you own — even with no internet at all. Plus the commercial-use licence. Full details →

Questions people ask

Does my photo get uploaded anywhere?

No. The image is decoded onto a canvas element inside this page, the watermark is drawn on top of it, and the result is saved straight from the tab to your disk. There is no server behind this tool — you can load the page and go offline.

Can I watermark a whole folder of photos?

The free page does one image at a time — set your watermark once and drop each photo in. The €9 download batch-processes entire folders in one pass with the same watermark settings, offline.

Where can I put the watermark, and can I tile it?

Nine positions (corners, edges, center) or a tiled diagonal pattern across the whole image. Size, opacity, color and rotation are all adjustable, with a live preview before you save.

Will watermarking reduce my photo's quality?

The watermarked image is saved as PNG, which is lossless — pixels are preserved. The file may be larger than the original JPEG. If you need an exact-size JPEG out, the paid download offers format options.
