A Complete Video Workflow in Your Browser

A typical end-to-end video task on UDT looks like this. You record something on your phone — landscape, with a few seconds of fumbling at the start and end. You want to post it as a vertical TikTok with your channel name in the corner, sized to fit the upload limit. Five tools, one chain.

Start with the Video Trimmer — set in and out points to drop the fumble, export. The trimmer stream-copies when the cuts land on keyframes, so this step takes seconds. Next, the Video Resizer with smart crop turns your 16:9 landscape into 9:16 vertical, with motion tracking that keeps the subject centered as it moves across the original frame.

Add a channel watermark with the Video Watermark tool — text in bottom-right at 60% opacity, or a logo PNG with the same positioning. Then, if the result is over TikTok's 500MB upload cap (rare for short verticals), run it through the Video Compressor with the TikTok preset. Done. The entire chain runs in your browser, with FFmpeg.wasm caching after the first download — every subsequent tool in the chain starts instantly.

Other common chains: extract audio from a recorded interview with the Audio Extractor, then run the MP3 through the Audio Transcription tool for searchable notes. Build a 10-second loop by trimming with the Video Trimmer then converting to GIF with the GIF Maker. Stitch several phone clips into one with the Video Merger, then rotate the result with the Video Rotator if any clip came in sideways.

The point of grouping these as a suite rather than just listing them is that every tool's output naturally becomes another tool's input. Pick the tool that matches your immediate next step; chain as far as your task demands.

Frequently Asked Questions about the Video Suite

Are all 12 video tools really free?+
Yes — every tool in the Video Suite is free with no time limits, no file size caps, no watermarks, and no signup. The site is supported by ads elsewhere; the tools themselves are unrestricted.
Do my videos ever leave my device?+
No. Every Video Suite tool runs FFmpeg.wasm — the WebAssembly build of FFmpeg — entirely in your browser. The 32MB engine downloads once across the whole suite and caches; after that, tools work offline. Your video files never touch a server.
Why does the first run download 32MB?+
FFmpeg.wasm is the WebAssembly port of FFmpeg, the same engine used by most desktop video editors. It downloads once to your browser cache, then runs every operation locally without re-downloading. Switching between Video Suite tools doesn't trigger another download — they all share the same cached engine.
Which browsers are supported?+
Chrome, Edge, Firefox, and Safari (recent versions). WebGPU acceleration is used when available (Chrome/Edge 113+, Safari 17+) for noticeably faster encoding. The tools also work on phones and tablets, with performance roughly 2–3x slower than a laptop.
What's the maximum file size?+
Limited by browser memory rather than any tool-imposed cap. Most modern laptops handle 1–2GB videos comfortably; phones cap around 500MB. For 4K+ files over 2GB, a desktop FFmpeg install will be faster than the browser version.
Will the output be watermarked?+
No. None of these tools add a watermark to the output. The free tools elsewhere that add watermarks do so as upsell pressure to their paid plans — we'd rather just serve ads on the surrounding pages.
Can I chain tools together (e.g., trim → compress)?+
Yes. Each tool's output is a downloadable file you can immediately drop into another tool. Common chains: Trimmer → Compressor (cut to length, then shrink to platform size), Resizer → Watermark (reframe for vertical, then add caption), Frame Extractor → an external image editor for thumbnails.
What's the underlying engine and license?+
FFmpeg.wasm v0.12.x with @ffmpeg/core v0.12.6, served from jsDelivr CDN. FFmpeg itself is LGPL-licensed; the wasm wrapper is MIT. UDT serves the engine unmodified and documents the version on every tool page — this is the LGPL-compliance posture.
