Hevcly: HEVC to MP4

Hevcly converts HEVC (H.265) video to H.264 MP4 on your iPhone or iPad, and nothing is uploaded. Your first 3 conversions are free; a one-time unlock makes it unlimited and adds batch convert.

iPhone video won't play on a PC, an older phone or a website upload? Hevcly re-encodes HEVC (H.265) video to H.264 MP4 — the format almost every player, browser and video editor can open.

Pick a video from your Photos library or from Files and tap Convert to H.264. Hevcly re-encodes it on your iPhone, shows the codec and file size before and after, and hands you an MP4 to save or share.

• REAL H.264, EVERY TIME — video is always re-encoded to H.264 with AAC audio in an MP4 file, never just re-wrapped. Hevcly checks the finished file and tries another encoding route if it would still be HEVC.
• HDR TO SDR — HDR clips, which recent iPhones record by default, are converted to standard SDR colour so they don't look washed-out and grey on screens without HDR support.
• AUDIO KEPT — the soundtrack comes along as AAC.
• PREVIEW AND COMPARE — play the original and the converted video in the app, and see the source codec (HEVC, H.264, ProRes …) next to the new file size.
• SAVE OR SHARE — save the MP4 to Photos, save it to Files, or send it from the share sheet.
• BATCH CONVERT — with the one-time unlock, select up to 50 videos and convert them in one go.

Honest scope: output is up to 1080p — 4K videos are scaled down to 1080p — and the result is always SDR, so HDR is not kept.

Everything happens on your iPhone. Nothing is uploaded and no account is needed.

No ads. No subscription. Just the one-time unlock.
