Free online photo watermark tool: reads EXIF to generate camera, lens, aperture, shutter and ISO watermarks and borders — 50 styles, batch-process many photos and export them one at a time at full resolution. Style gallery · Guide & FAQ
I’m a student who loves photography, and the solo developer behind Mark. Servers, domains, test devices and multi-platform work are all self-funded. The tool stays free; if it helped you share a photo a little more beautifully, you’re welcome to buy me a coffee. Support is never a requirement — it’s the fuel for the next fix and the next style. Thank you for taking photos seriously with me.

These payment apps are China-only. If you can’t use them, starring the project or opening a friendly issue on GitHub helps just as much.

On by default, can be turned off anytime. Only anonymous feature counters are sent (style used, export success, app version) to help improve the product. Photos, file names and shooting data are never uploaded — regardless of this switch.
