Free car proof tool — stamp your photos before valet

Snap a photo of your car and CarShake stamps the date, time, and location onto it. Timestamped proof against valet, rental, or parking damage — free, no signup, nothing leaves your phone.

Tip: take one photo before you hand over the car and one after you get it back.

Want this automatic? The CarShake app captures GPS-verified, dual-timestamped, AI-checked before/after records for you — so you have airtight proof without thinking about it. See how CarShake works →

How it works

  1. Add a photo — tap and take a picture of your car (or pick one you just took).
  2. Add location — type where you are; optionally tap "Use my GPS".
  3. Stamp it — CarShake overlays the date, time, and location.
  4. Download — save the stamped photo. Repeat before and after the valet.

FAQ

Is this free?

Yes — free, no signup. Everything runs in your browser; your photos never leave your device.

Does the timestamp prove when the photo was taken?

It stamps your device's current date and time onto the image as a visible record. For the strongest proof, take the photo at the moment you hand over or collect the car — one before, one after.

Do my photos get uploaded?

No. All processing is local in your browser. Nothing is uploaded anywhere.
