Any file. Any shape.

Free Video Tools

Trim, extract audio from, and mute video files entirely in your browser — no account, no upload, and no file-size limit. Trimming and audio extraction don't re-encode anything: they copy the original video/audio data straight into a new file, the same "smart cut" technique professional editors use, so a multi-gigabyte file finishes in seconds instead of minutes.

This is the one thing free server-based video tools structurally can't offer — accepting a multi-gigabyte upload and paying the CPU cost to re-encode it is expensive to host for free. Doing the same work locally, without uploading or re-encoding, costs nothing and has no size ceiling beyond your own device's memory.

There's also a waveform-based Audio Trim for standalone MP3/WAV/OGG/M4A files — a different tool from the lossless video ones, since a standalone audio cutter needs to decode and re-encode by nature. See the FAQ below for which one to use.

How lossless video trimming actually works

A compressed video file is really two things stacked together: the encoded picture and sound data (the bulk of the file), and a small index describing which bytes belong to which frame and when each one plays (its container). Trim Video and Extract Audio only ever touch the index — they read just enough of it to find the exact byte range covering the time range you asked for, then copy those bytes verbatim into a freshly built index for the new, smaller file. The actual picture and audio data is never decoded, decompressed, or re-encoded, which is exactly why there's no quality loss and no waiting.

The one real constraint this technique has is keyframes. Most video frames are encoded as a difference from the frame before them, so a cut can only start cleanly at a frame that stands on its own (a keyframe) — starting mid-chain would show a broken or frozen image until the next keyframe arrives. Trim Video's timeline marks every keyframe and snaps your in-point to the nearest one at or before your selection, so what you get is always a clean cut, never a glitch.

FAQ

Why is trimming a 2GB video instant here, when other tools take minutes?
Because nothing gets re-encoded. Trim Video and Extract Audio copy the original compressed video/audio bytes straight through into a new container — the same technique professional editing software calls a 'lossless' or 'smart' cut. Server-based tools that accept multi-gigabyte uploads either can't (size caps) or spend CPU time decoding and re-encoding every frame, which is what actually takes minutes.
Why does the trimmed clip sometimes start a fraction of a second before or after what I dragged the slider to?
Video is stored as a chain of frames where most frames only make sense relative to the last full frame (a keyframe) before them — cutting mid-chain without re-encoding would produce a broken, glitchy start. So the actual cut point snaps to the nearest keyframe at or before your selection. The timeline shows exactly where the keyframes are so this is never a surprise.
Is my video uploaded anywhere?
No. Every tool on this page reads the file directly from your device using the File System Access APIs already built into your browser — only the small header/metadata region and the exact byte range you asked to keep are ever touched, and none of it leaves your machine.
What video formats are supported?
MP4, M4V and MOV — including ProRes MOV, since trimming and audio extraction never decode the video itself, only the container around it. WebM and MKV (Matroska) use a completely different container format and aren't supported yet.
Is Audio Trim the same lossless technique as Trim Video?
No, and that's intentional. Audio Trim works on standalone audio files (MP3, WAV, OGG, M4A) and shows a waveform for precise, sample-accurate selection — it decodes and re-encodes, the same as any audio editor's export. Extract Audio from Video is the lossless one: it copies a video's existing audio track without touching it. Use Extract Audio from Video when you just want a video's audio as-is; use Audio Trim when you need to cut a standalone audio file.
