Convertir MP4 a WebM

Going from MP4 to WebM takes a couple of clicks: drop the file in, download the result. Drop in your MP4 file (a .mp4) and download a ready-to-use WebM file (a .webm) — no software to install, no account to create, and no watermark on the output.

What is MP4?

MP4 (H.264) is the most compatible video format in the world — it plays on virtually every device, browser and social platform.

What is WebM?

WebM is an open, royalty-free video format built for the web, usually VP9 or AV1 — smaller than MP4 at similar quality and well supported in browsers.

Why convert MP4 to WebM?

You'll reach for a MP4 to WebM conversion whenever the other end expects WebM specifically — uploading somewhere, importing into software, or sharing with someone whose device prefers it. The conversion runs through ffmpeg, the industry-standard media engine, re-encoding the streams with sensible high-quality defaults so the result plays cleanly on your target device.

When you'd convert MP4 to WebM

You might be optimising images for a faster-loading page, exporting for a specific app or marketplace, or just making sure a colleague on a different device can open what you send.

Is it private?

Privacy is the default here. Your MP4 file is uploaded over an encrypted connection, converted, downloaded the moment it's ready, and then deleted automatically a short time afterwards. We never keep your files, never build a library of your content, and never make you sign up to download the result.
