Your iPhone shoots HEIC by default. Half the internet still expects JPG. That mismatch shows up as rejected uploads, blank previews on Windows, and "unsupported file type" errors in forms that worked fine last year. Converting is the fix, and you do not need a computer to do it.
What you'll need
Just the photos and a converter app on the phone itself. Web converters exist, but they mean uploading your pictures to someone's server and waiting on your connection. On-device conversion is faster for batches and keeps the photos private.
Converting with HEIC,JPEG,PDF Media Converter
- Open the app and tap the input area to select photos. Pick one, several, or a whole album.
- Choose JPEG as the output format.
- Set the quality slider. Higher quality means bigger files; the app shows an estimated size per photo so you can decide before converting. Around 90% is visually indistinguishable from the original for most photos.
- Pick a destination — Photos, Files, a Google Drive folder, or keep the copies in the app.
- Tap Convert. Done. Your originals stay untouched; the JPGs are new files.
Three details worth knowing
- Originals are preserved. Conversion creates copies. Your camera roll keeps the HEIC versions with all their quality.
- Strip GPS if the photo is leaving your circle. There is a toggle right on the convert screen. HEIC and JPG both carry location metadata; turning this on removes it from the output file.
- Everything runs offline. Airplane mode works fine. Nothing is uploaded anywhere.
When you have hundreds to convert
One-at-a-time selection stops making sense past a dozen photos. The app can select entire albums, scan your library for every HEIC it contains, or take a date range — then convert the lot in one run. That workflow has its own guide below.
