How to use Image DPI Checker
- Choose an image.
- Click Check DPI.
- Read its dimensions, file size and DPI.
- Note: most web images carry no DPI value — see the FAQ.
Note: this tool runs in your browser. Nothing is uploaded.
Honest limit: Reads DPI only when the file actually stores it (PNG pHYs or JPEG JFIF). Most web images store no DPI — that is reported honestly, not guessed.
Frequently Asked Questions
Is Image DPI Checker free?
Yes, it is 100% free with no sign-up.
Why does my image show "no DPI stored"?
Most photos and web images do not store a DPI value at all. DPI only matters for printing, and many files simply leave it blank.
What DPI do I need for printing?
Printers usually want 300 DPI. A 3000 × 2400 px image prints at 10 × 8 inches at 300 DPI.
Is my image uploaded?
No. The file header is read entirely in your browser.
