Check a photo
Image size checker
Find out a photo's exact size in pixels and KB, its DPI and print size, and whether it hides your location. Then check it against an upload form's limits.
How to check an image's size
- Choose or drop a photo. It opens in your browser and is never uploaded.
- Read its pixel size, file size, file type, shape, DPI and the largest size it prints sharply.
- Under Check it against, pick a form or website, or type in your own limits, to see if the photo will be accepted.
- If something fails, follow the link to fix it: compress, resize, crop or convert.
What the numbers mean
| Pixels | The width and height of the picture in dots. Online forms usually set a minimum and maximum, for example 600 × 600 to 1200 × 1200. |
|---|---|
| File size | How much space the file takes, in KB or MB. Upload forms often set a limit such as 100 KB or 2 MB. Here 1 KB = 1000 bytes, like most forms. |
| DPI | A note inside the file saying how many pixels to print per inch. It doesn't change the photo itself. Many photos don't have one. |
| Print size at 300 DPI | The largest size the photo prints sharply. Bigger prints are possible but look softer. |
| GPS location | Phones often save where a photo was taken. The checker tells you if your photo carries a location before you share it. |
Why does a website say my photo is the wrong size?
- Too many KB: phone photos are often 2–5 MB. Compress it to the limit, for example 100 KB or 50 KB.
- Wrong pixel size: resize it to the size the form asks for.
- Wrong shape: many forms want a square photo. Crop it to a square.
- Wrong file type: iPhone photos are often HEIC. Convert HEIC to JPG.

Is it safe?
Yes. Your photo is read by your own browser. It is never uploaded to a server, so nobody else can see it or its location.
