Video Trimmer
Cut a section out of a video without uploading anything. Pick the start and end, preview the selection, and FileTinker records just that part in your browser — your video never leaves your device.
How to trim a video
- Add your video above — common formats like MP4 and WebM work. It's read locally in your browser, never uploaded.
- Drag the start and end handles to the part you want to keep, and play the looping preview to confirm the selection.
- Export and download. FileTinker re-records just that section in your browser and gives you the trimmed clip.
About trimming video
Trimming a video keeps only the section you want — cutting dead air from the start, clipping a highlight, or shortening a recording before you share it. FileTinker lets you set the start and end on a timeline and preview the selection on a loop before you commit, then records that part out as a new file. Common formats such as MP4 and WebM work, depending on the codecs your browser supports.
The trim runs entirely in your browser: your video never leaves your device and nothing is stored online, which matters for personal clips and screen recordings. Because the selected section is re-encoded by your browser as it's recorded, the file size or quality can shift slightly from the original — for everyday clips the difference is minimal.
