Split long videos. Keep every pixel.
HEVCut slices long iPhone videos into equal parts in seconds. No re-encoding, no quality loss, just clean shareable clips that fit through WhatsApp, iMessage, and email.
Most splitters re-encode. HEVCut doesn't.
AVFoundation passthrough copies the original bitstream into each segment. Pixels are not re-compressed; parts are visually indistinguishable from the source.
A 45-minute 4K clip splits in under a minute on a modern iPhone. Pure remuxing, no transcoding tax.
Splitting runs locally with the same media frameworks Photos uses. Your video never leaves the phone.
Three taps. The math is automatic.
- 01
Find the long videos
HEVCut surfaces every clip in your library over 20 minutes, grouped by length. Pick one to split.
- 02
Choose how many parts
Pick a segment count: 2, 3, 4, or more. HEVCut shows the resulting length per part so you can match a sharing limit exactly.
- 03
Save back to Photos
New parts land in your Photos library, ready to share or AirDrop. The original stays untouched.
Common questions.
- Does splitting drop quality?
- No. HEVCut uses passthrough export, so the encoded bitstream is copied directly into each part with no re-encoding. The pixels are byte-for-byte identical to the original.
- How fast is it?
- Much faster than a full transcode. A 45-minute 4K HEVC clip typically splits in under a minute on a recent iPhone because there's no encoder work, just file remuxing.
- Can I pick exact timestamps?
- Splits are evenly spaced by part count today (2 parts, 3 parts, etc.). HEVCut snaps each cut to the nearest keyframe so every part plays cleanly from the first frame.
- Does it work with iCloud Photos optimized storage?
- Yes. If the original isn't on-device, HEVCut pulls it from your Photo Library first (you'll see a download indicator in the progress sheet), then performs the split locally.
- What happens to the original?
- Nothing. The split outputs are new files added to Photos. The original sits exactly where it was so you can delete it manually if you no longer need it.
- What formats are supported?
- Anything iPhone records natively: HEVC, H.264, ProRes, Slow-Motion, Cinematic. The exporter uses the same container as the source, so the output plays everywhere the original plays.
Free up space. Keep your memories.
HEVCut runs on iPhone, iPad and Mac. Everything stays on-device, offline. Try a few compressions before committing to Pro.
