What to Do When a Form Won't Accept HEIC Photos

Published: Oct 19, 2026 | Updated: Oct 19, 2026 | About (Japanese)

Key points
  • Many forms accept only JPG or PNG
  • Convert HEIC to JPG before uploading
  • If large, compress further

If you see "Invalid file format" on upload, the iPhone photo being HEIC may be the cause.

Steps

  1. Use "Convert HEIC to JPG" to turn the photo into JPG.
  2. Upload the saved JPG to the form.

If there's a size limit

JPG can still be large. Use "Compress & Resize Images" to fit a limit such as 1 MB or 2 MB.

For photos of documents

If you're submitting photos of documents as a PDF, "Photos to PDF" can make the PDF directly.

Checks

Use "Convert HEIC to JPG" (free)
