Image upload fix
Image Won't Upload
Convert images to a more accepted format when a form, CMS, marketplace, or app rejects WebP, HEIC, AVIF, PNG, or GIF files.
This fixes
- The upload form says the file type is not supported.
- A CMS or marketplace accepts JPG but rejects WebP, HEIC, or AVIF.
- You need a safer image copy for a strict form.
How to handle it
- Check the file extension requested by the destination.
- Convert modern image formats to JPG for maximum compatibility.
- Use PNG when sharp screenshots or transparency matter.
Before you submit
- JPG does not preserve transparent backgrounds.
- PNG may be larger than WebP or AVIF.
- Open the output before submitting the form.
