The problem

Cutting a minute shouldn't mean re-encoding the lot

Most video cutters decode and re-compress the whole file just to drop the first minute: slow, lossy and often watermarked.

Re-encoding for every cut

Typical editors re-compress the entire video to remove one minute, which takes ages on a long recording.

A softer picture every save

Each re-encode throws away detail, so trimming the same clip twice makes it visibly worse.

A watermark on your trim

Free trial cutters often stamp their logo on the result, or cap how long your video may be.

Upload a huge file to cut it

Online trimmers want your whole video on their servers first, and long recordings are often over their limit.

Cuts that land somewhere else

Some lossless cutters start a part early or late without saying why, and the first frames can come out broken.

Ads and bundled installers

Freeware cutters with pop-ups, offers and toolbars tucked into the installer.

Vow Lossless Trimmer & Joiner fixes all of it.

How it works

Mark. Export. Done.

Stream copy keeps every frame exactly as it was, and your video never leaves your PC.

Features

Precise cutting tools in a window that stays simple

For gamers, streamers, parents, teachers and anyone with long recordings: quick for one trim, deep enough for a whole folder.

No re-encoding, no loss

Stream copy writes the parts you keep exactly as they were: the original quality, done about as fast as copying the file.

Honest keyframe hints

Before you export it tells you when a lossless cut has to start on a keyframe, and by how much. One click cuts on the exact frame instead.

Frame-accurate smart cut

With Unlimited, H.264 and H.265 cuts land on the exact frame: only the frames up to the next keyframe are re-encoded, the rest is copied.

Many parts per file

Keep or cut out as many segments as you like, as one file or a file each, with names, undo and redo, and cuts remembered per file.

Lossless joining

Join clips into one file without re-encoding, with a plain-language compatibility check, a free preview of the joins and a chapter per file.

Batch whole folders

Trim the start or end, keep a stretch, split, change the format or save the sound for every file in a folder at once.

Let it find the cuts

Cut out silences or black parts, or make one segment per scene, in one click. Split by chapters, minutes, equal parts or megabytes.

Tracks and formats

Keep or drop each sound and subtitle track, save one on its own, or switch between MP4, MKV, MOV and TS without re-encoding.

A timeline built for precision

Zoom down to single frames, with thumbnails, the sound waveform and keyframe marks, plus J, K and L, frame steps and keyframe jumps.

Light and dark theme

Work in the light theme or the dark one: a click on the sun or moon at the bottom of the side bar switches it.

Light & dark theme

Easy on the eyes, day or night.

Lossless Trimmer & Joiner comes with a crisp light theme and a calm dark theme. Switch with one click, or let it follow your Windows setting by itself. It remembers your choice.

Step-by-step guide

How to trim a video without losing quality on Windows

Cut the parts you don't want out of any video in under a minute, at the original quality.

Step 1: get it free
  1. Download and install it free

    Get Vow Lossless Trimmer & Joiner from this page and run the installer. It installs per user without administrator rights, asks for no account and brings everything it needs, so nothing downloads on first run.

  2. Open your video

    Drag it onto the window or press Ctrl+O. The player and a zoomable timeline with thumbnails, the sound waveform and the keyframe marks appear in a moment.

  3. Mark the start and end

    Play to where the part begins and press I, then to where it ends and press O. Press B to add another part, or type exact times such as 1:23.5 in the segment list.

  4. Check the hint

    If a lossless cut can't start exactly on your mark, the Export card says how much earlier it will start. That's normal for lossless cuts; with Unlimited, Cut exactly removes it.

  5. Press Export

    Press Export or Ctrl+E. The new file is written next to the original in seconds and shows up under Saved, ready to play, show in Explorer or drag into another app.

FAQ

Questions about Lossless Trimmer & Joiner

Is Vow Lossless Trimmer & Joiner really free?

Yes. You can trim 5 files a day for free, any length, with as many segments as you like, every track and format option, the silence, black and scene finders, snapshots and cut lists. Trimming the same file again the same day is free, and nothing is watermarked. Unlimited, a one-time $4.95 USD payment, adds joining, batch, frame-accurate smart cuts and splitting, and removes the daily limit.

What does lossless mean here?

The parts you keep are copied straight from the original (stream copy) instead of being decoded and compressed again. The picture and sound stay exactly as they were, and even a long recording is cut in seconds.

Why does my cut start a little earlier?

A video can only start cleanly on a keyframe, so a lossless cut begins on the keyframe before your mark. The app tells you before you export, for example "starts 1.3 s earlier, on a keyframe". With Unlimited, the frame-accurate smart cut starts on the exact frame by re-encoding only the frames up to the next keyframe, for H.264 and H.265.

Can it join videos without re-encoding?

Yes, with Unlimited, when the clips share the same format, as phone or camera clips usually do. The free join check explains in plain words which file doesn't match and why, Make it match converts only the odd ones, and the preview of the joins is free.

How is it different from LosslessCut, Avidemux or Bandicut?

Like them it cuts without re-encoding. On top it adds a frame-accurate smart cut verified by tests, plain-language join checks with one-click matching, a true batch queue, and keyframe-exact copies that avoid starting a keyframe early on B-frame video. There is no watermark and no throttling, in a simpler window.

Which files can it open?

MP4, MKV, MOV, TS and MTS, AVI, WebM and sound files such as MP3 and M4A, and most other formats FFmpeg reads. Videos the player can't show directly, like H.265, MPEG-2 or VC-1, get a small preview copy automatically; the cut always uses the original.

Is my original file changed?

Never. The new file is written next to the original, or in a folder you choose in Settings, and nothing is overwritten unless you ask for it. A stopped or failed export leaves no half file and gives the day's use back.

Is it safe to install?

Yes. It is made and published by XTO Pty Ltd, an Australian company. The installer contains no ads, no toolbars and no bundled software, needs no administrator rights, and uninstalls cleanly from Windows Settings.
