Drag a visual timeline to cut the part you want, join clips into one in any order, and export to MP4, WebM, MP3, M4A or WAV. No signup needed to start trimming.
Every cut happens on your device with ffmpeg.wasm — your video is never uploaded to a server. Flip on airplane mode and it still works, so a confidential recording or NDA footage never leaves your machine.
Drop in a video or audio file. It loads straight into the browser tab — nothing is sent anywhere, so there are no upload waits or server size limits.
Drag the handles to set your in and out points and preview the selection. Add more clips and order them however you like to join them into one.
Pick MP4, WebM, MP3, M4A or WAV and ffmpeg.wasm renders the result locally. The finished file saves to your downloads — still never uploaded.
No. Trim runs entirely in your browser using ffmpeg.wasm, so your file is read, cut and exported on your own device. Nothing is uploaded, stored or sent anywhere — you can confirm it by turning on airplane mode and trimming offline.
Yes, trimming and joining are free with a generous tier and no signup to try. Pro ($9/mo or $69/yr, or $4/mo for this app alone) unlocks full-resolution exports, batch and ZIP, no watermark, and unlimited history across every nimbril tool.
Yes. Add several clips, arrange them in any order, and export them as a single file. It works for both video and audio.
You can export to MP4, WebM, MP3, M4A or WAV. That covers standard video as well as audio-only output if you just need the sound.
Because nothing uploads, there are no server-imposed size caps. Processing happens on your device, so the practical limit is your computer's available memory rather than an upload quota.
