Description
Cut and join videos without losing a single pixel. TrimKeep copies the frames of your clip as they are — no re-encoding, no quality loss, and it takes seconds, not minutes.
Why it's different
Most editors re-compress every video you save. Here, trimming and joining keep the original quality bit for bit, and a 4K clip is saved almost instantly. When you add effects, the video is encoded once with the phone's hardware encoder — fast and in high quality.

- Mark the start and the end, cut out the extra parts
- Join several videos into one — in a second, without re-encoding

Questions & answers
What does “lossless” mean?
When you only trim, join or rotate, the app copies the compressed frames as they are. The result is bit-for-bit the same quality as the original and is saved in seconds.
Why does the cut start a bit earlier?
A lossless cut can start only on a keyframe. The app shows exactly where the result will start. With effects added, the cut is frame-accurate.
Are my videos uploaded anywhere?
No. Everything is processed on your phone, offline. There is no account and no server.
Is there a watermark?
No. No watermark, no ads, no subscriptions.
Where is the saved video?
Tap “Save to Photos” or “Share…” on the Done screen. On iPhone the file is also in Files → On My iPhone → Video Editor.
