# Video Trimmer > Trim video clips to the exact second in your browser. No upload, no size limit, no watermark — FFmpeg runs on your own device. - URL: https://farvixo.com/tools/video/video-trimmer - Category: Video Tools (https://farvixo.com/tools/video) - Price: Free - Last reviewed: 7 August 2026 - Publisher: Farvixo Technologies ## What is Video Trimmer? Video Trimmer is a free browser-based video tool from Farvixo that lets you cut and trim video clips precisely. It uses an in-browser FFmpeg build compiled to WebAssembly, so even large clips are processed on your own machine and never uploaded. No account, no watermark and no per-file size limit imposed by a server. ## Specifications | Property | Value | | --- | --- | | Tool | Video Trimmer — Video Tools | | Purpose | Cut and trim video clips precisely | | Input | A single file (MP4, WebM, MOV, AVI, MKV) | | Output | Video file in the selected container and codec | | Processing | In your browser — files are never uploaded to a server | | Price | Free, unlimited, no account required | | Limitations | Bounded by your device's memory and CPU rather than a server quota; very large files may be slow on older hardware | ## How to use Video Trimmer 1. **Load your video** — Select a video file in Video Trimmer. Conversion happens in your browser using WebAssembly, so even large files never get uploaded anywhere. 2. **Pick format and quality** — Choose the output format, resolution and bitrate — or start from a ready-made preset if you are not sure what to pick. 3. **Convert and save** — Start the conversion and watch the progress bar; longer clips take a little time because the work runs on your own machine. Download when it finishes. ## Use cases - Getting a clip under the size limit for WhatsApp, Gmail, Discord or a course upload - Converting a recording to a format a specific player, editor or platform accepts - Editors who want a quick change without opening a full desktop suite - Handling confidential footage that must not be uploaded to an online converter ## Tips - Processing speed depends on your own CPU, since the work is local. A laptop on battery-saver will be noticeably slower. - H.264 (MP4) is the safest choice for compatibility; VP9 or AV1 give smaller files but decode slowly on older devices. - Leave the tab open and visible — a backgrounded tab gets throttled by the browser and the encode will crawl. ## Common problems - **The encode is very slow** — Everything runs on your device rather than a server farm. Pick a lower resolution or a faster preset, keep the tab in the foreground, and close other heavy tabs. - **The output has no sound** — The chosen container cannot carry the source audio codec — WebM cannot hold AAC, for example. Re-encode the audio instead of copying the stream. - **The browser ran out of memory** — The clip is too large to hold in memory. Trim it into shorter segments and process them one at a time. ## FAQ ### Does trimming re-encode the video? Not if you trim on keyframes — the streams are copied, which is instant and completely lossless. Trimming to an arbitrary frame requires re-encoding the section around the cut, which takes longer and costs a little quality. ### Why is my cut a second off from where I set it? Fast, copy-based trimming can only cut at keyframes, which occur every few seconds. Enable precise mode to cut exactly where you asked; it re-encodes, so it is slower. ### Is there a limit on file size or length? No. Nothing is uploaded, so there is no server limit and no queue. The ceiling is your device memory and patience. ### Can I cut a section out of the middle? Yes. Remove-selection mode cuts the middle out and joins the remaining start and end together. ### Which formats can I trim? MP4, WebM, MOV, AVI, MKV and most others, since FFmpeg handles the decoding. The output container matches the source unless you choose otherwise. ## Related tools - [Video Converter](https://farvixo.com/tools/video/video-converter): Convert videos to MP4, WebM, MKV, MOV, GIF or extract MP3/AAC — AI analysis, batch queue, social presets, 100% private FFmpeg in your browser - [Video Compressor](https://farvixo.com/tools/video/video-compressor): Shrink videos to a target file size — hit 16 MB for WhatsApp or 25 MB for email with two-pass encoding, live size prediction and no visible quality loss, 100% private in your browser - [Video Merger](https://farvixo.com/tools/video/video-merger): Join multiple videos into one file - [Video Splitter](https://farvixo.com/tools/video/video-splitter): Split a video into equal parts - [Video Watermark](https://farvixo.com/tools/video/video-watermark): Add text watermarks to videos - [Video to GIF](https://farvixo.com/tools/video/video-to-gif): Turn video clips into animated GIFs --- > Machine-readable index: [llms.txt](https://farvixo.com/llms.txt) · full corpus: [llms-full.txt](https://farvixo.com/llms-full.txt) · agent skill: [skill.md](https://farvixo.com/skill.md).
