Find PNG Dimensions
Drop a PNG (or any image) and read its exact width and height in pixels, the simplified aspect ratio, and the megapixel count. It's read in your browser, so nothing uploads — handy when you just need the numbers without opening a heavy editor.

What you get
- Width × Height in pixels — the true pixel dimensions of the file.
- Aspect ratio reduced to its simplest form (e.g. 16:9), computed from the greatest common divisor.
- Megapixels — width × height ÷ 1,000,000, the figure cameras quote.
FAQ
How do I check the size of a PNG in pixels?
Drop it above and click Measure — width, height, aspect ratio and megapixels appear at once, read entirely in your browser.
Does it change the file?
No — this only reads the dimensions. To actually change them, use Resize or Change aspect ratio.
Can I check several images at once?
Yes — drop a batch and each gets its own report. Great for auditing a folder of assets.
Part of: Work out what is wrong with a PNG
Start with the validator. It tells you whether the file is broken or merely unexpected, which are different problems.
- 1 PNG validator Signature, chunk order and CRCs, checked
- 2 Chunk viewer Every chunk in the file and what it holds
- 3 Inspector Dimensions, bit depth, colour type, metadata
- 4 Color count Whether it is really as complex as it looks
- 5 Dimensions What the pixels actually measure
