Video Clip Maker is a free, in-browser video tool. Cut a single clip out of any video by picking start and end timestamps. Files are processed entirely in your browser with FFmpeg WebAssembly — fast, lossless stream-copy, no uploads. The page exposes a small surface — input, controls, output — so a first-time visitor can complete the job without reading documentation.
Architecturally, Video Clip Maker is a single-page client. The processing layer is FFmpeg compiled to WebAssembly; the UI is a thin React shell on top. MP4, WebM, MOV, MKV, AVI, FLV, and OGV inputs flow through the engine and the output is returned to the browser as a Blob you can save or copy. The 500 MB cap is the only hard limit and it exists to keep memory usage stable on every device.
Video Clip Maker is a static page plus a client-side engine. The browser does the work; there is no separate backend in the loop for the actual processing. That architecture is why the tool starts immediately, why it does not depend on the load on a remote service, and why running multiple jobs in a row does not slow it down.
Anyone who works with video editing and conversion on a casual basis — students submitting video assignments, product teams shipping release demos, event organisers sharing highlight footage — finds Video Clip Maker a quick way to get the result. The page loads in under a second, the controls are visible from a single screen, and the result downloads or copies in one click.
Reach for Video Clip Maker when you need a predictable result on a single file. The page works on the first visit, the controls are visible without a menu, and the output is delivered the moment the engine finishes.
Constraints worth knowing about: inputs are capped at 500 MB to keep memory usage in a sensible range, one input is processed per run, and the tool must be loaded over HTTPS for the in-browser engine to work. These are properties of the architecture.
For multi-step jobs, Video Clip Maker sits next to Video Trimmer, Video Segment Remover, and Video Loop. None of them depend on each other — you can use Video Clip Maker on its own — but together they cover the common variations of the task this page exists to handle.
Some notes on the design of Video Clip Maker. The page is intentionally narrow: one input, the controls relevant to the task, and one output. Adding unrelated features would make the common case slower for the majority of users, so the surface is held to what people actually use.
Video Clip Maker returns the result as `{name}-edited.{ext}`. If you are running multiple jobs, the output names will not collide as long as the input names differ. You can re-run with different settings as many times as you like; each run produces a fresh file with no caching trickery in between.
Some background on the design choices behind Video Clip Maker: every option you see on the page is there because a real workflow needs it, and every option that is not shown has been deliberately omitted to keep the common case fast. The bias is toward minimal-but-complete.
Video Clip Maker produces deterministic output: the same input plus the same options always produces the same result. That predictability matters when the result has to match an upstream specification or be reproducible later.
A few practical tips that experienced users of Video Clip Maker pick up over time. First, keep your default browser updated — the engine relies on standard web APIs and newer browser versions are noticeably faster than ones from a few years ago. Second, close other heavy tabs before processing a large input; the engine shares CPU and memory with whatever else is open. Third, if you re-run the same kind of job often, your last-used settings are remembered for the rest of the tab session, so subsequent runs are essentially one click.
When something goes wrong, the cause is usually one of three things: a malformed input, a browser that is out of memory, or a corporate proxy that is interfering with the page's static assets. The first two are easy to diagnose; the third typically requires asking your IT team to allow FFmpeg compiled to WebAssembly to load.
Video Clip Maker is one of many single-purpose tools in the catalog. Each is built around the same single-page model. Use this one, close the tab, and come back the next time you need the same job done. None of the tools require prior knowledge of the others — each page is self-contained.
A WebAssembly build of FFmpeg loads in this page and uses `-ss` (seek) plus `-t` (duration) plus `-c copy` to slice your video without re-encoding — the streams are copied directly into a new MP4. This is essentially instant even for 4K footage.
Most video tools have to re-encode every pixel — slow because WASM is single-threaded. The clip maker just copies the existing video and audio streams into a new container, so it runs at disk-read speed instead of decode-then-encode speed.
Even stream-copy requires reading every byte of the source file. Server tools have faster disk and network I/O. The trade-off is total privacy — your file never leaves your device.
Start time snaps to the nearest keyframe (typically every 1–2 seconds). For frame-perfect cuts, use the Video Trimmer tool which re-encodes the affected boundary frames.
No — stream-copy is byte-perfect. Output quality is identical to the source.
Up to 500MB. Stream-copy is very memory-efficient since no decoding happens, so even long sources usually clip without issue.
Yes — both the video and audio streams are copied through. Use the Mute Video tool first if you want to drop the audio.
No. The clipping runs entirely in your browser tab. Nothing is transmitted, stored, or logged. Closing the tab erases the file from memory immediately.
Video Clip Maker processes one input at a time by design — it keeps memory usage predictable on lower-end devices and makes results easier to verify. To handle a folder, run the tool once per file; the page stays loaded between runs and remembers your last-used settings, so the second run is essentially instant.
Video Clip Maker is a browser-only tool by design and does not expose a hosted API. The reason is the same as the privacy story: there is no Favtoo backend doing the work, so there is no service to call. If you need to script the same transformation, the underlying engine (FFmpeg compiled to WebAssembly) is open-source and can be used directly from your own code.
Video Clip Maker accepts MP4, WebM, MOV, MKV, AVI, FLV, and OGV. If your input is in a format that is not directly supported, convert it first using one of Favtoo's converter tools — every Favtoo converter outputs a file that is a clean input to the next tool in the chain.
Failures usually fall into one of three buckets: the input is in an unsupported format, the input is over the size cap, or the input is structurally malformed (a truncated download, a partial export, or a stream the engine does not recognise). The first two are easy to confirm — check that your file is one of MP4, WebM, MOV, MKV, AVI, FLV, and OGV and that it is below 500 MB. For the third, opening the file in its native viewer first is the fastest way to confirm the source is intact.
Most jobs finish in seconds. Speed scales with input size and with how many CPU cycles your browser tab has available — the engine runs in your browser, so it shares resources with whatever else you have open. For inputs near the 500 MB ceiling, expect anywhere from a few seconds to roughly a minute on a typical laptop. Closing other heavy tabs noticeably speeds things up.
Once the page is loaded, Video Clip Maker can complete jobs without an active internet connection — the engine is bundled with the page, so there is no per-job network call. The initial page load does require a connection (to fetch the static assets), but after that you can disconnect entirely and the tool will still work. This is a side-effect of the local-first architecture, not a deliberate "offline mode" feature.
Video Clip Maker runs in any modern mobile browser — Safari, Chrome, Firefox and the in-app browsers in most messaging apps all support the underlying APIs. Performance depends on the device: a recent phone handles typical inputs nearly as fast as a laptop, while older devices may take a few seconds longer near the 500 MB ceiling. The interface lays out cleanly on small screens, so you do not need to pinch-zoom to see the controls.
Video Clip Maker is a static page running an open-source engine in your browser, so a typical corporate firewall does not get in the way as long as it allows JavaScript and WebAssembly to load from Favtoo. For teams that need to host it themselves on an internal network, the underlying engine (FFmpeg compiled to WebAssembly) is open-source and can be packaged into a private build with the same behaviour. Reach out via the Contact page if that is something you are exploring.
Video Clip Maker works in any modern browser released in the last few years — Chrome, Edge, Firefox, Safari, Brave, Arc and the major Chromium derivatives are all supported. The underlying engine relies on widely-supported web APIs, so there is nothing exotic to install. If you are on a very old browser version and the tool fails to load, updating to the latest release of your preferred browser is the only fix needed.
