Why iPhones make HEIC files
Since iOS 11, iPhones save photos as HEIC (High Efficiency Image Container) — roughly half the file size of a JPG at the same quality. Great for your storage; terrible the moment the photo needs to open on Windows, an Android phone, an older app, a government upload form, or basically anything that isn't Apple.
Why this converter is different
| This site | Typical converter sites | |
|---|---|---|
| File limit | None — your RAM is the limit | 20-200 files, then pay |
| Upload wait | None — nothing uploads | Upload + queue + download |
| Privacy | Files never leave your device | "Deleted after 1 hour," trust us |
| Signup | Never | Often, past a few files |
FAQ
Does it keep the original resolution?
Yes — full resolution, including 48MP ProRAW-adjacent shots. Big photos are processed one at a time to stay inside your device's memory.
My HEIC is from iOS 18/26 and other converters fail on it.
We use the current HEIC decoder (most free converters run a 2021-era one). New iPhone photos, including HDR HEICs, work — HDR shots come out as the standard-look SDR image every app understands.
Where do the photos go?
Nowhere. Decoding happens in your browser's memory and the JPGs save straight to your Downloads folder. Airplane mode works.
Can they download automatically?
Flip Auto-download in the header — single files save instantly, batches zip themselves into one download.
