Tool guide
Free Online Video Trimmer
Trim one video by choosing the exact section to keep with a dual-handle range control or numeric start and end times. Formatza previews the selected points and creates a newly encoded clip in your browser.
Steps
How it works
- Choose one supported video file up to 250 MB and wait for its duration to load.
- Drag the start and end handles or enter times in seconds with millisecond precision.
- Preview the selected positions and confirm that the start is before the end.
- Trim the video, preview the new clip, and download the completed output.
Highlights
Key features
- Dual-handle range selection keeps the chosen section of the video.
- Numeric controls accept start and end values to three decimal places.
- Keyboard controls support standard, one-second, and fine time adjustments.
- Maps the selected video stream and optional audio stream into the trimmed output.
- Exports MP4/MOV input as MP4 and WebM input as WebM with progress and output preview.
Use cases
Common uses
- Remove unwanted footage from the beginning or end of a recording.
- Cut a short highlight from a longer MP4 or WebM video.
- Prepare a focused demonstration or social clip.
- Shorten a recording before sharing or archiving it.
Notes
Limitations to know
- The tool trims one video at a time and does not support batch video cutting.
- The output is re-encoded, so trimming is not lossless and quality may change.
- Times are accepted to 0.001 seconds, but encoded frame boundaries can cause small differences from the requested point.
- The minimum selected duration is 0.01 seconds, and the input file limit is 250 MB.
- Browser memory, source codecs, and long files can affect processing time or completion.
FAQ
Frequently asked questions
What is the difference between trimming and cropping?
Trimming changes which part of the timeline is kept. Cropping removes pixels from the edges of every video frame.
Can I enter exact timestamps?
Yes. Enter start and end times in seconds with up to three decimal places, or use the range handles and keyboard controls.
Is trimming frame accurate?
The tool re-encodes from the requested time, but actual encoded frame boundaries can produce a small timing difference. It does not promise frame-perfect cutting.
Does the trimmed clip keep audio?
The optional source audio stream is mapped and re-encoded when FFmpeg supports it, keeping it aligned with the selected range.
Can I preview the selected section?
The original player seeks to the active start or end point while you adjust the range, and the completed clip has its own output preview.
