School yearbook submissions usually ask for JPG photos. iPhones save photos as HEIC by default. That mismatch is easy to miss until the upload form rejects a photo you know is perfectly good — often close to the submission deadline, when there is no time to troubleshoot.

Why the yearbook form rejects your photo

Yearbook software and print workflows were built around JPG. HEIC is newer and smaller, but many submission portals, email inboxes, and layout tools still do not accept it. The error is rarely helpful: "invalid file type" or a greyed-out file picker, with no mention of HEIC at all.

The fix is not to change how your iPhone shoots. Keep shooting in HEIC — it saves storage. Convert copies to JPG only for the submission.

Do not just rename the file

Renaming photo.heic to photo.jpg changes the name, not the contents. The file is still HEIC data inside, and the form will still reject it — or worse, accept it and then fail at print time. A real conversion rewrites the image data as JPG.

Convert copies to JPG in your browser

If you need JPGs quickly, you can convert HEIC to JPG for school yearbook submissions entirely in your browser: the conversion happens on your own device, nothing is uploaded, and no account is needed. Then check each JPG before uploading — confirm it is the right way up, fully in frame, and the photo you meant to submit.

Steps that work for most yearbook portals:

  1. Pick the photos you plan to submit and keep the HEIC originals untouched.
  2. Convert copies to JPG, one per photo, at full quality.
  3. Open each JPG and check orientation and cropping — yearbook layouts crop tightly, so a sideways photo is hard to fix after submission.
  4. Name files clearly (for example, lastname-firstname-grade.jpg) if the portal does not rename them for you.
  5. Upload the JPGs and confirm the preview thumbnails match what you selected.

A few yearbook-specific tips

  • Group photos: check every face is visible after conversion; HEIC-to-JPG conversion does not crop, but the portal's own preview might.
  • Old photos from parents' phones: if a photo came from an older iPhone backup, it may already be JPG — converting it again is harmless but unnecessary.
  • Deadlines: convert a day early. Yearbook advisers can usually fix a wrong file, but only before the layout locks.
