DPI Checker for Exam Photos
Government exam portals require photos with a minimum DPI (resolution). If your photo is below the threshold, it looks pixelated and gets rejected. This tool instantly reads your photo's DPI so you know before uploading. No files leave your device.

Common DPI Problems
Phone cameras default to 72 DPI
Most phones save photos at 72 DPI. This is below the 100-200 DPI minimum required by exam portals.
Scanner set too low
If you scanned a passport photo, make sure your scanner is set to 300 DPI, not the default 150.
Cropping reduces effective DPI
When you crop a photo aggressively, the remaining area may have too few pixels to meet the DPI requirement.
Screenshots are always 72 DPI
Never use a screenshot of your photo. Take or scan the original at high resolution.
Frequently Asked Questions
What is DPI and why does it matter for exam photos?
DPI (Dots Per Inch) measures how much detail a photo contains. Higher DPI means clearer, sharper images. Exam portals require minimum DPI so your face is identifiable during verification. A photo under 100 DPI may appear pixelated and get rejected.
How do I check my photo's DPI?
Use our DPI Checker tool — simply select your photo and it instantly reads the DPI metadata from the image file. No upload to any server needed. You can also check in Windows by right-clicking the image → Properties → Details, but our tool is faster and also validates other exam requirements.
My photo's DPI is too low. How do I fix it?
If your photo was taken with a phone camera, it's usually 72 DPI by default. You need to either (1) rescan the photo at higher DPI if it's a scanned passport photo, or (2) use our photo dimension fixer which can adjust DPI metadata while maintaining quality.
Does changing DPI change the file size?
Changing only the DPI metadata does not affect file size — it changes how the image is interpreted for print size. However, resampling an image to increase actual pixel density will increase file size. Our tool lets you check and adjust DPI without changing your photo's appearance.
