Online Video Converter
Convert any video format to MP4 – fast, free, and fully online

From Upload to MP4 in a Snap
Whether it's WebM, MKV, MOV, or even that mysterious VOB file from 2009 that’s been collecting digital dust in your PC, Flixier makes it simple to convert your videos straight to MP4, without having to bother with installations. Just drag, drop, convert, and move on. Next time you’ve got stuff to post and no time to waste, Flixier’s fast, cloud-powered conversions have your back.
Make Any Video MP4-Ready
Not every video format plays nice with everyone. If, for instance, you have a WebM from a browser-based tool, Flixier easily converts WebM to MP4, the internet’s most compatible format, in just a few seconds. Same for converting VOB to MP4.
Turn Old Formats Into Modern Content
Got clips in outdated video formats like VOB, MPEG, or AVI? Turn them to MP4 to make them editable, shareable, and streamable again – perfect for digital archives, portfolio refreshes, or saving old home videos from obscurity.
Share Easily on Any Platform
LinkedIn prefers MOV. Instagram wants MP4. TikTok won’t even look at your MKV. Instead of juggling requirements, convert your videos to MP4 and post everywhere without second-guessing. Flixier helps you stay visible across all channels with minimal effort.
Shrink Large Files to Make Them Shareable
Big video files can be a real headache – slow to upload and difficult to share. Flixier lets you convert bulky formats into compressed MP4s that still look great but move faster, then share them by email, direct link or publish them online.
How to Turn Any Video into MP4
To start, click on the “Get Started” button on the homepage. Once you get to the editor, click on “Import or Record” button at the top of your screen, drop in a local file or pull one from Google Drive, Dropbox, OneDrive, even Twitch or YouTube.
Once your video lands in the editor, it’s play time. Cut, caption, translate, narrate – shape your video however you want. When you're ready, hit “Export”, select “Video” and you’ll automatically get an MP4 file in your downloads.
Download your MP4, save it to the cloud, send a share link, or open it in Flixier’s full editing studio if you need more polish. You can also publish your video anywhere without worrying about compatibility.
