trimy

trimy is a local browser video editor centered on trimming and joining video without re-encoding when possible, plus crop and timeline arrangement. It supports both video and audio tracks, can detach or add audio, and aims to keep exports efficient by using stream copy when possible. Compatible clips can join without re-encoding, and mixed sequences can copy matching segments while re-encoding only incompatible clips, timeline gaps, or audio that needs normalization.

What trimy does

trimy is a local browser video editor centered on trimming and joining video without re-encoding when possible, plus crop and timeline arrangement.

Supported formats

  • MP4
  • MOV
  • AVI
  • MKV
  • WebM
  • common audio companions like MP3 and WAV

Why it is different

  • Timeline workflow with both video and audio tracks.
  • Can join compatible clips without re-encoding through stream-copy paths.
  • Can partially re-encode mixed sequences instead of always rendering the full timeline.
  • Can switch between lossless, precise, mixed, and re-encode export strategies.
  • Designed to handle larger local media files than a typical lightweight browser trimmer.

Privacy and local processing

Editing and export happen locally in the browser. The tool is designed around client-side processing for sensitive or large video files.

FAQ

Can trimy cut without re-encoding?

In supported scenarios, yes. trimy can use lossless, packet-copy, or stream-copy export paths where the source and operation allow it.

Can trimy join videos without re-encoding?

Yes, when the clips are compatible. trimy can stream-copy matching clips into one joined file instead of decoding and re-encoding the video.

What happens when only one clip in a sequence does not match?

trimy can use a mixed copy-normalize path: matching segments stay stream-copy, while only incompatible clips, timeline gaps, or audio that needs normalization are encoded before the final join.

Can I add external audio?

Yes. You can detach, preserve, replace, or add audio on the timeline.

Does it only trim single clips?

No. It also supports crop, join, clip ordering, and more complete timeline editing flows.
