How Universal File Upload Checker works

Check file size, type, dimensions and aspect ratio for common upload destinations, with private local inspection.

What you provide
An image or PDF and a destination preset or custom maximum size.
What FileFix returns
A local pass/fail report for relevant type, size, dimensions and aspect-ratio checks.
Practical limit
It checks known technical rules, not the destination site's content review or current server-side validation.
