When a photo needs to prove when it was taken
On a construction site, during an inspection, or for any kind of documentation photo, having the date and time burned directly into the image means anyone looking at it later knows exactly when it was taken, without needing a separate note or caption.
This is general information, not a compliance guarantee
A visible timestamp is a helpful practical habit, but if you need photos for legal, insurance, or regulatory purposes, check the specific documentation requirements for your situation, since acceptable formats and standards vary by organization and jurisdiction.
Frequently Asked Questions
Does the default camera app really have no timestamp feature?
Most default camera apps only save the capture time in the photo's hidden metadata rather than displaying it on screen, so a dedicated app is needed to burn a visible stamp into the image.
Can I remove a timestamp afterward?
A stamp burned directly into the image is difficult to remove cleanly through editing, so it is a good idea to keep the original, unstamped photo saved separately if you might need it later.
