Youth wrestling club registrations usually ask for a player photo or a photo ID upload, and the form often accepts PDF only. iPhones save photos as HEIC by default, so a perfectly good photo can be refused with a vague "invalid file type" message — sometimes only after you have filled in the whole registration form.
1. Keep the HEIC original
Do not overwrite your original. Convert a copy for the registration and keep the HEIC master, in case the club later asks for a clearer photo for the membership card or the tournament roster.
2. Do not just rename files to .pdf
Renaming changes the extension, not the contents. The file will still be HEIC data, and the portal will still reject it.
3. Convert the copies to PDF for the registration
If you need PDF files quickly, you can convert HEIC photos to PDF for youth wrestling club registrations entirely in the browser: the conversion happens on your own device, nothing is uploaded, and no account is needed. Then check each PDF before submitting — confirm your child's face is clearly visible, the photo is the right way up, and nothing important is cropped out.
