Image Dimension Checker
Width, height, megapixels and file size.
Image Dimension Checker is its own job in the catalog (metadata): Width, height, megapixels and file size. It is not a copy of the resizer or converter with a new title — the operation is “inspect”.
Controls on this page: preview and download. Output defaults to the format shown.

Questions about this tool
Does Image Dimension Checker upload my file?
No. Processing is in this browser.
Can I use this on a phone?
Yes, with the same file-size cap (about 25 MB). A large photo is slower on a phone CPU than on a laptop.
Does Image Dimension Checker upload the file?
No. This tool runs in the tab. See Privacy for decoder notes (HEIC, PDF.js worker).
What is the file size cap?
About 25 MB per file. Very large pixel counts are rejected so the tab stays responsive.
