Split videos without losing quality
Most mobile editors quietly re-encode everything on export: banding creeps into skies, fine detail goes soft, HDR gets flattened to washed-out SDR. Then the platform you upload to compresses it again.
Split Video Into Parts preserves resolution, HDR and bitrate when it cuts. The only compression your video ever meets is the one you cannot avoid — the platform's own.
What “no quality loss” means here
The specifics, not the marketing.
| Resolution | Preserved up to 4K |
|---|---|
| HDR | Preserved — no SDR flattening |
| Artifacts | No re-encode banding or softness added |
| Processing | On-device — no cloud transcoding step |
Your source file's codec and bitrate are respected on export. What you shot is what each part contains.
How to split without quality loss
Import the original
Work from the source file in Photos or iCloud Drive — not a version already exported through another editor.
Split any way you like
By time, by number of parts, or manually with the slider and frame-exact timecodes.
Export
Parts save in full quality. No settings to get wrong — quality preservation is the default, not an option buried in a menu.
Verify it yourself
Open a part in Photos and check the info panel: resolution and frame rate match your original.
Where quality usually dies — and doesn't here
No cloud round-trip
Online splitters upload, transcode on a server, and hand you back a compressed file. Here nothing leaves the device.
HDR stays HDR
Dolby-bright skies and neon nights keep their range instead of getting crushed to SDR gray.
One compression, not three
Original → split → platform is the whole chain. No intermediate encode inserting artifacts along the way.
Shoot in 4K HDR, split into parts, and every segment carries the full image data of the original — verifiable in the Photos info panel.
Frequently asked
How does the app keep full quality?
It avoids unnecessary re-encoding and preserves the source resolution, HDR metadata and bitrate when writing each part.
Do other apps really degrade video when splitting?
Many do — re-encoding at a lower or default bitrate is common, and cloud-based tools compress twice: once on upload, once on processing.
Does it support 8K?
Not yet — quality preservation currently covers footage up to 4K, which includes everything iPhones shoot.
Will HDR survive posting to Instagram or TikTok?
The app hands the platform a full-quality HDR part. What the platform does next is its own pipeline — but you have avoided adding a second layer of loss.
Are the split parts the same file size per minute as the original?
Approximately yes, since bitrate is preserved. A 10-minute 4 GB video splits into parts totaling roughly 4 GB.
