Free Video to MP4 Converter

A video to MP4 converter rewrites a clip into the MP4 container, usually with H.264 video and AAC audio. This page does it inside your browser, which helps when a phone, editor or social app rejects a MOV, WebM, MKV or AVI file.

1. Click Choose files and select your video. 2. Leave Quality (%) at 85 or enter another value from 1 to 100. 3. Click Create file and wait for the progress bar to finish. 4. Play the result, then click Download.

No. FFmpeg runs in a worker inside this tab, reads the file from your device and writes the MP4 back into browser memory. Only the engine itself is downloaded from a CDN, so the recording stays on your computer or phone.

Yes, it’s free and works without an account. SocQ doesn’t add a watermark, logo or end screen, so the MP4 contains only your own footage.

The picker accepts common video types such as MOV, WebM, MKV, AVI and MP4. Whether a file opens depends on the codec inside it, not just the extension. If you see an error, test a few seconds of the same recording to check support.

Each video can be up to 100 MB and 10 minutes long. Files beyond either limit return an error instead of an MP4. For bigger recordings, trim or split them first and convert each part separately.

Every re-encode loses a little detail, because H.264 is a lossy codec. At the default of 85 the difference is hard to spot on typical social clips. Move the value toward 100 if you plan to edit the MP4 again.

Yes, as long as the source has an audio track. Sound is encoded as AAC at 128 kbps, which plays on phones, browsers and editing apps. Clips recorded without audio produce a silent MP4.

The first time you click Create file, the page downloads the FFmpeg engine, a large WebAssembly file. Your browser keeps a cached copy, so later conversions start sooner. Encoding speed also depends on your device’s processor.

Output size depends on the quality value and on how efficient the original codec was. A phone MOV often shrinks, while an already compressed WebM can grow. Lower the quality value for a smaller file, or raise it to keep more detail.
