Why this free video converter is fast on Clipy
Two things make a video converter feel slow: the upload leg and the encode leg. Most free converters do both badly. Upload goes to a single bucket in a single region, so a user halfway around the world spends 30 seconds shipping bytes before ffmpeg even starts. Then encode runs in a shared queue on a single instance. We fixed both halves. Upload uses a presigned URL straight to the nearest Backblaze B2 POP, so the upstream leg is whatever your local connection can sustain to the closest edge — no Atlantic crossing required. Encode runs on dedicated workers with native ffmpeg, which is orders of magnitude faster than browser-wasm ffmpeg and free of its memory limits. The finished file is delivered through Bunny CDN, so the download is also pulled from the closest edge.
What this tool does, exactly
The converter on this page does one job well: it takes any common video and produces a clean, universal MP4 — H.264 video with +faststart and yuv420p, AAC audio — the combination that plays on every phone, browser, editor, and social platform. One file in, one MP4 out, delivered through Bunny CDN. It does not output WebM, GIF, or MP3 itself; each of those is a different encoder with its own trade-offs, so they live on dedicated pages: MP4 to WebM (VP8 + Vorbis for the open web), video to GIF (a two-pass palette for cleaner colours), and MP4 to MP3 for audio. Browse the full converter hub for every format pair.
When to pick each format
Reach for MP4 when you want something that plays everywhere — phones, TVs, every browser, every editor — and you're not sure where it's going. Pick WebM for the open web: smaller than MP4 at the same quality, royalty-free, ideal for a background loop or a self-hosted player. GIF is for short, silent, auto-looping clips dropped into Slack, a README, or a Linear issue — keep it under about 10 seconds or the file balloons. MP3 is for when the picture doesn't matter: a recorded interview headed to a podcast feed, or audio you'll feed into a transcript service.
Sister tools
If you already know exactly what you're converting, the dedicated pages have format-specific controls and copy. Use video to MP4 converter for the universal target, WebM to MP4 or MP4 to WebM to swap between the two web video codecs, video to GIF when you want frame-rate and width sliders, video to audio to pull a clean MP3 out of any recording, or video compressor if the file is already MP4 and just too big.
Where the files come from
A converter is only useful if you have something to convert. If you're recording the source yourself — a product demo, a bug repro, a quick walkthrough — Clipy captures your screen and webcam in the browser with no watermark and no install, then hands you a clean MP4 you can run straight through this page. Record once, then export to whichever format the destination wants.
