Common causes
- An iPhone photo renamed to .jpg
- iPhones save HEIC files. Renaming one to .jpg doesn't change what's inside, and portals read the inside.
- A progressive JPG
- Some portals read only plain (baseline) JPGs and call anything else a format error, even when size and KB are right.
- Two file endings
- Names like photo.jpg.jpg or scan.pdf.pdf are refused as "more than one extension".
- Print colours (CMYK)
- Scanners and design apps sometimes save CMYK; portals expect ordinary RGB.
- A turn flag instead of a real turn
- Phones often mark a photo to be turned rather than turning it; portals that ignore the mark see it sideways.
- Wrong pixels, shape or KB
- Over the maximum, under a minimum, or the wrong shape for the form.
