Edit and protect your photos without uploading them.

GuardMe adjusts colour, strips hidden location and camera data, and cloaks faces against recognition. Every step runs inside your browser tab, and the browser itself is told to block any upload.

How it works

Three steps. None of them leave your device.

  1. 1

    Drop a photo

    Drag it in, paste it, or pick it from your library. It is read into this tab’s memory, and its metadata is shown to you straight away.

  2. 2

    Adjust

    Brightness, contrast, saturation, hue, warmth and clarity, with live preview and hold-to-compare. One click applies the house preset.

  3. 3

    Protect & export

    Choose your protections, then export. The new file is checked for leftover metadata before you download it.

Protections

Choose exactly what happens to your photo.

Nothing is switched on without you, and everything that runs is written to a log you can read.

Fresh re-encode

Only pixels are written to the new file. EXIF, GPS, XMP and comments are left behind.

Always on

Deep metadata scrub

Also wipes data that can hide inside the pixels, such as hidden watermarks in the lowest bit of each colour. The change is invisible.

Face cloaking

Uses Fawkes, from the University of Chicago, to add tiny changes to faces so recognition models learn the wrong identity. Photos without faces are left as they are.

Runs on your own computer · beta

Face cloaking makes recognition harder. It is not a guarantee, and it does not stop every kind of AI use. We say that in the app too.

Don’t take our word for it

Privacy you can check yourself.

Most apps ask you to trust their privacy policy. GuardMe shows you the evidence, live.

  • Test the lock. One button tries to send a message out. You watch the browser refuse it.
  • Live security log. It counts every outgoing request and every blocked attempt.
  • Tamper alerts. If an extension or antivirus rewrites the page’s security policy, you’re told.
  • Readable code. The whole app is a few plain files with no build step, so anyone can see what it does.
