Does this read EXIF data like camera settings?

No, it reads basic file and pixel-dimension metadata only, not embedded EXIF tags.

What is the aspect ratio calculation based on?

It's the width and height reduced to their simplest whole-number ratio using their greatest common divisor.

Is the file uploaded to a server to read metadata?

No, the File and Image APIs read everything locally in your browser.

Does it work offline and on mobile?

Yes. Once the page has loaded it keeps working without a network connection, and the layout is responsive so it stays usable on phones and tablets.

Do I need an account or an API key?

No. Every tool on Coders Hub is free to use with no sign-up, no API key and no usage limits.
