Cut the part you actually need
A 20-minute recording where the useful part is 40 seconds; a phone clip with fumbling at both ends — trimming is the most common edit there is, and it shouldn’t require installing an editor. Enter a start and end time and get just that section.
Trimming here is lossless: the video is cut without re-encoding, so it completes in seconds regardless of length and the quality is byte-for-byte identical to the original.
How to trim a video
Drop a video above, enter start and end times (in seconds, or mm:ss), and press Trim. The first use downloads the engine (~31 MB, cached afterwards); the cut itself is nearly instant because nothing is re-encoded.
Unlike most online converters, FileLark never uploads your files to a server. The conversion runs entirely inside your browser using modern web technology, which means it works offline once the page has loaded, there are no file size queues or daily upload limits, and your images can never be stored, scanned, or leaked — they simply never leave your device.
One technical note
Lossless cutting can only start at a keyframe, so the actual start may land up to a couple of seconds before the time you enter (never after — you won’t lose content). For frame-exact cuts, trim slightly wide here, or run the clip through the video compressor afterwards, which re-encodes and snaps the boundaries precisely.
