Task
Check an image's dimensions, format, and file size

Still rejected? Troubleshooting
- I only want to check, not change anything
- That's fine — if every requirement passes, the tool tells you the file is ready to upload as-is.
Private by design. Your file is read and fixed entirely in your browser — it is never uploaded. You can verify this yourself.
