How to Verify If a Photo Is Real or Manipulated

Most misleading photos aren't fakes. They're real pictures with the wrong caption: a flood from 2019 shared as last night's storm, a protest in one country presented as happening in another. Edited and AI-generated images exist too, and they're getting harder to spot, but if you only have time for one check, find out whether the photo is older than the story attached to it.

Here's the order we'd go in.

1. Find out if the photo already existed

Run a reverse image search on several engines and look for the oldest copy. Some engines can sort matches by date, which helps. If the picture was online before the event it supposedly shows, you have your answer. It's real, but it isn't what people say it is.

While you're there, read the captions on the other copies. If the same image circulates with three different stories, at most one of them is right.

2. Look at the file

If you have the original file rather than a screenshot, check its metadata. A capture date, a phone model and GPS coordinates that fit the claim are a good sign. Coordinates in another country, or a date long before the event, are not.

Don't lean on it too heavily. Metadata is missing from most images shared online, and it's easy to edit. It can support a conclusion, but it rarely settles one.

3. Check the place and the time

Does what you see match where and when the photo is supposed to be from? Signs in the wrong language, the wrong license plates, cars driving on the wrong side of the road are quick giveaways. So is the season: trees in full leaf in a photo said to be from Oslo in January, or heavy coats in Madrid in August.

If the sun is out, the shadows should fit the claimed time of day. The weather is another easy check, since historical records for most cities are available online. A sunny photo of a day when it rained all afternoon needs explaining.

PixTrace runs the image search, the metadata check and the location analysis together, which gets you through these first three steps quickly.

4. Look for signs of editing

Edited photos often break the physics of the scene. Shadows should all fall the same way. Reflections in windows and water should match what's in front of them. Pasted elements tend to have edges that are too sharp or slightly haloed, a different amount of grain or blur from their surroundings, or a perspective that doesn't line up with the rest of the image.

Zoom in wherever something might have been added or removed. Patterns that repeat exactly, in a crowd, a brick wall or a patch of grass, can be a sign that part of the image was copied over another.

5. Consider whether it was generated

Image generators have improved a lot, and the old giveaways like six-fingered hands and garbled text are much less reliable than they used to be. It's still worth looking at hands, text, jewellery and the background, where generators tend to cut corners: railings that melt into walls, windows that don't line up, signs that look like words from a distance and aren't.

Some cameras, editing apps and AI tools now attach Content Credentials, a signed record of how an image was made and edited. You can check a file at contentcredentials.org/verify. Most images don't carry them yet, so their absence proves nothing, but when they're there they help.

6. Go back to the source

The strongest check is often the simplest one: find the person who took the photo and ask. Ask for the original file, other pictures from the same moment, and where exactly they were standing. Someone who was really there can usually answer quickly and in detail.

None of these checks settles it alone. What you want is agreement, with the source, the file, the place, the time and the image all telling the same story. When one of them doesn't fit, that's where to dig.
