Video Stabilizer is built for video editing and conversion jobs that fit cleanly into a browser tab. Reduce camera shake in handheld footage using FFmpeg's deshake filter (single-pass). Pick mild, medium, or strong stabilization. Files are processed entirely in your browser with FFmpeg WebAssembly. The processing runs in the page itself, which is why the controls update instantly when you change settings and why a freshly loaded page is ready to do real work the moment it becomes interactive.
If you fit any of these descriptions, Video Stabilizer should slot cleanly into your workflow: product teams shipping release demos; educators editing lecture clips; teams compressing demo recordings. The tool keeps the controls focused on what matters for each of these use cases.
The execution path is auditable from the page itself: open developer tools, switch to the Network tab, run a job. The requests you see are static-asset GETs for the engine and the page resources. The actual work is JavaScript code running against the bytes already in your tab's memory.
Technically, the work is done by FFmpeg compiled to WebAssembly, loaded as part of the page. Inputs in MP4, WebM, MOV, MKV, AVI, FLV, and OGV format are recognised automatically and validated before the engine begins processing. Files up to 500 MB are supported per run; that ceiling keeps browser memory usage stable on a wide range of devices.
The right moment to reach for Video Stabilizer is when you have a focused video editing and conversion job that fits inside a browser tab. Open the page, drop in the file or paste your input, choose the options that matter, and the tool returns the result.
For multi-step jobs, Video Stabilizer sits next to Video Slow Motion, Video Timelapse, and Video Rotator. None of them depend on each other — you can use Video Stabilizer on its own — but together they cover the common variations of the task this page exists to handle.
The download is delivered as `{name}-edited.{ext}` the moment processing completes — no email link, no "your result will be ready in 5 minutes" queue, no expiry timer. The file is generated in your browser and saved by your browser's normal download flow.
The 500 MB ceiling on input size is the only fixed limit. Output files are produced in standard formats that every common viewer recognises, and the tool runs the same way regardless of how many times you have used it during the session.
Some notes on the design of Video Stabilizer. 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.
A short note on how Video Stabilizer came to look the way it does: every iteration started by watching how someone unfamiliar with the tool actually used it, then removing whatever got in their way. That is why the upload area dominates the screen, the run button is bigger than the secondary controls, and the result panel is unmissable when the job finishes.
Useful patterns when working with Video Stabilizer: keep the input file open in another tab so you can compare against the result; give the output file a descriptive name when saving so you can find it later (the default name is sensible but generic); and treat each run as independent — the tool has no concept of "history", which means you cannot accidentally pollute one job with leftovers from another.
Common gotchas worth flagging: Video Stabilizer only accepts MP4, WebM, MOV, MKV, AVI, FLV, and OGV, so if your file is in another format you will need to convert it first. The 500 MB ceiling is per-file, not per-session; you can run as many separate jobs as you like, but a single oversized input will be rejected on load.
As a single-page tool, Video Stabilizer stays focused on one video editing and conversion step. Multi-step workflows are composed by chaining adjacent tools — each tool produces a standard file the next one can read directly, so a longer pipeline is just a sequence of short tab-and-tab visits.
Video Stabilizer is intentionally narrow in scope so the common case is fast and the result is predictable. If you ever need a variation it does not cover, browse the rest of the catalog — there is a good chance an adjacent tool already exists, and switching between tools is just a matter of opening another tab.
A WebAssembly build of FFmpeg loads in this page and uses the `deshake` filter, which detects motion between consecutive frames and shifts each frame to compensate — entirely on your device.
Server tools use multi-threaded native FFmpeg (often with the more advanced two-pass `vidstab` plugin). WebAssembly is single-threaded and runs the simpler `deshake` filter, typically 5–10× slower than a native two-pass run. The trade-off is total privacy: your video never leaves your device.
Deshake is a single-pass filter — great for mild to moderate handheld wobble (walking, light wind). It is less effective than two-pass solutions like `vidstab` for severe shake or extreme rolling-shutter wobble.
Yes — slightly. To compensate for camera motion the filter has to shift each frame, which exposes empty edges. Stronger settings crop more aggressively.
Mild for slight tripod wobble. Medium for typical handheld walking footage (recommended starting point). Strong for very shaky action footage — but expect noticeable cropping.
Partially. Deshake corrects translation but not the warping caused by rolling shutter on fast pans. For severe rolling shutter, use a dedicated NLE.
Up to 500MB. Stabilization re-encodes every frame and is one of the slower operations — start with shorter clips to gauge processing time.
No. The stabilization runs entirely in your browser tab. Nothing is transmitted, stored, or logged. Closing the tab erases the file from memory immediately.
Video Stabilizer is updated whenever the underlying engine releases an improvement or a bug fix. Because the tool is delivered as a static page, every visit fetches the latest version automatically — there is no "version" to manage on your end. If a particular release ever changes default behaviour, the change is documented on Favtoo's changelog so you can confirm what shifted.
Video Stabilizer uses native HTML controls wherever possible, which means keyboard navigation, focus rings, and screen-reader labels work the way the platform expects. The drop zone accepts files via the keyboard-accessible file picker as well as drag-and-drop, and result downloads use standard browser download flows. If you spot an accessibility gap, Favtoo treats it as a bug worth fixing.
Video Stabilizer can be used for personal and commercial work alike — there is no separate "business" licence to purchase. The output you generate is yours to use however you want, including in client deliverables, internal documents, or commercial products. Favtoo's only ask is fair, individual use; the tool is not designed to be embedded as a backend service or wrapped behind an API for resale.
Video Stabilizer 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.
Inputs are capped at 500 MB per file, which keeps memory usage stable across phones, tablets and older laptops. You can run Video Stabilizer as often as you need; every run produces a full-quality result.
Video Stabilizer 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 Stabilizer only needs the standard web platform — file picker access for the inputs you choose to load, and optionally clipboard access if you copy the result rather than downloading it. There is no microphone, camera, geolocation or background-permission request, because none of those are needed for the work the tool does. Some browsers prompt the first time WebAssembly is compiled; that is a normal one-time event, not specific to Favtoo.
Video Stabilizer 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.
Once the page is loaded, Video Stabilizer 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.
