About the MP4 Converter
Our free online MP4 converter transcodes any video file — WEBM, MOV, AVI, OGG, and more — into a standard MP4 for maximum compatibility. It's useful for playing a recording from an unusual source on any phone, tablet, computer, or TV, uploading to platforms that only accept MP4 files, or simply standardizing your video library on the most universally supported format.
Unlike most online tools, conversion happens entirely inside your browser using the Canvas API and the native MediaRecorder API — your video is never uploaded to a server. That means it's fast, works without an internet round-trip, and keeps your files completely private and secure.

Frequently Asked Questions
Which video formats are supported?
We support all major video container formats including WEBM, MOV, AVI, and OGG. If your browser can play the video, this tool can convert it.
Are my files private?
Yes. All encoding and recording happen locally in your web browser — no files are uploaded to our server.
Why convert to MP4?
MP4 is the most widely supported video format in the world, playing natively on almost any phone, tablet, computer, or smart TV — unlike less common formats like WEBM, AVI, or OGG.
Will the audio track be preserved?
No. This tool re-records the video through a canvas, which only captures the visual frames — the output MP4 is silent.
Does it cost money?
No. The MP4 converter is 100% free to use, with no registration or account required.
