Video Cutter
Choose start and end points in a video and save that section as a new file. The browser re-records the section while it plays, so it takes as long as the clip; the result is WebM, or MP4 where WebM recording is unavailable.

About the Video Cutter
Open a video, mark the part you want with the Start and End sliders, check it with Preview, and press Cut Video. The file never leaves your device, and there is no upload to wait for.
It is worth knowing how the cut is made, because it explains the speed and the output. Browsers have no simple built-in function for cutting a video file, so this tool plays your selection and records it again while it plays. Each frame is copied onto a hidden canvas and captured at up to 30 frames per second, and the sound is captured through the Web Audio API. Both go to the browser's MediaRecorder. A 2-minute selection therefore takes about 2 minutes to cut, and you will see and hear it play. Keep the tab in front: browsers pause the frame copying in background tabs.
The new file keeps the original's width and height, but it is re-encoded, so expect some quality loss and a different file size. It is saved as WebM in browsers that can record WebM (Chrome, Edge and Firefox) and as MP4 where only MP4 recording is available, as in some Safari versions. The download button shows which format you got.
It works well for short jobs: taking the 20 seconds that matter out of a long screen recording, sharing one moment from a phone video, or trimming the dead time at the start of a meeting clip. For long selections or full-quality edits, a desktop video editor that cuts without re-encoding is a better choice. To turn a short moment into an animation, try Video to GIF, and for sound-only files use the Audio Cutter.

Limitations
- Cutting takes as long as the selected clip, because it is recorded in real time.
- The video is re-encoded at up to 30 frames per second, so quality and frame rate can be lower than the original.
- Output is WebM, or MP4 in browsers without WebM recording. WebM files may not open in some older players, and some players cannot show their length or seek in them because browsers often write no duration information.
- The tab must stay visible during recording; switching away can freeze frames in the output.
- Only videos your browser can play can be opened. Most AVI files, and in some browsers HEVC (H.265) video, will not open.
Privacy
The video is played and recorded entirely in your browser; neither the file nor the cut clip is uploaded to FlexyPdf's servers.
Frequently asked questions
Why does cutting take so long?
The selection is played and recorded in real time, so a 90-second clip takes about 90 seconds. Browsers have no simple built-in function for copying part of a video file directly.
Why is my clip a WebM file?
WebM is the format Chrome, Edge and Firefox record in. Current versions of these browsers and VLC play WebM. If you need MP4, convert the file with a desktop tool.
Does it work on iPhone or in Safari?
Safari 14.1 and later can record, and when WebM recording is not available the result is saved as MP4. Older Safari versions show a notice that recording is not supported.
Will the quality be the same as the original?
Not exactly. The frames are re-encoded at up to 30 frames per second with a bitrate based on the video size, so fine detail and fast motion can look softer.
Why is there no sound in my clip?
Check that the original has sound in Preview. If the browser blocked the audio capture, the clip is recorded without sound; try again in Chrome or Firefox.
