About the Image Dimensions Viewer

Dimensions, aspect ratio in lowest terms, megapixels, file size and whether the image contains any transparency - the facts you need before resizing or converting it.

The bytes-per-pixel figure is a quick quality indicator: a heavily compressed JPEG sits around 0.1, a lightly compressed one around 0.5, and an uncompressed format at 3 or 4.

Questions people ask

Is your image uploaded to a server?

No. This tool runs entirely in your browser using standard web APIs, so your image never leaves your device. You can confirm it by opening your browser's network panel while the tool runs, or by disconnecting from the internet after the page has loaded.

Is it free, and do I need an account?

Yes, it is free, and there is no account, no sign-up and no watermark on the result. The project is funded by optional donations.
