How to use it
Drop a video, mark the part you want, and save it as an MP4. Or switch to “Remove selected” to cut parts out. Your video stays on your device.
Drop your video onto the box above. It plays as normal, with a strip of frames along the timeline so you can see exactly where to cut.
Drag across the filmstrip to mark a section, drag its edges to adjust, or type exact times. Click anywhere to play from that point.
Choose “Keep selected” to save only the parts you marked, or “Remove selected” to cut them out and keep the rest — perfect for removing pauses and mistakes. The bright parts of the filmstrip are always what you’ll get.
Only the part you keep is processed, so cutting 30 seconds out of a two-hour video is quick.
FAQ
Can I cut a bit out of the middle?
Yes. Mark it and switch to “Remove selected”. The rest is joined together.
Can I keep several separate parts?
Yes. Mark them all and leave it on “Keep selected”. They’re joined in order.
Does trimming lower the quality?
Very slightly. Leave the size on “Original” and quality on “Balanced” and you won’t notice.
How long a video can I trim?
Any length. Only the part you keep is processed.
Which formats work?
MP4, MOV, M4V, WebM, and MKV. You get an MP4 back.
Can I trim just the sound?
Yes — extract the audio first, then use the audio trimmer.
How it worksFor the curious
Both modes are one operation: “remove these ranges” is converted to “keep the ranges between them”, so overlapping selections and edge cases behave identically. A selection covering the whole file correctly leaves nothing to save.
Cutting re-encodes. Compressed video stores most frames as differences from earlier ones, so a mid-file frame cannot be read without decoding its dependencies, and the kept piece must be written as a self-contained stream. That is one generation of loss; “Original” frame size and “Balanced” quality keep it minimal.
A single-range trim starts from the key frame before your chosen point and drops what precedes it, so the first frame is a real frame rather than a smear. Time fields accept tenths of a second. Output is MP4 with H.264. To trim only the sound, extract the audio first, then use the audio trimmer.
