What does Upload Checker inspect?

Depending on the file and preset, it checks format, byte size, pixel dimensions and aspect ratio.

Can it repair a failed file?

The report points to the relevant AG File Tools compressor or resizer so you can make the needed change.

No. A destination may apply additional or newly changed rules, so its current official requirements remain authoritative.

No. Your files never leave your device. Processing happens privately in your browser.

Find out whether a file matches its destination requirements, then fix it.
