About Video Converters
Drop a video above and choose the format you need. Our converters handle everything from shrinking large MP4 clips for social media to turning MKV movies into widely compatible MP4, or extracting the audio as MP3. Conversions keep your video looking sharp, run without any software install, and require no sign-up. Whether you're preparing a clip for YouTube, freeing up storage, or making a file play on an older device, every tool below is free, secure, and works on any device. Files are processed privately and deleted automatically after conversion.
MiConvert converts between MP4, AVI, MOV, MKV, WEBM, WMV, FLV and more, plus pulls audio out of any video as MP3, AAC, or WAV. It's built for the everyday cases people actually hit: a phone-recorded MOV that won't upload to a Windows-only tool, a downloaded MKV movie that a smart TV can't play, or a screen recording that needs to become a lightweight WEBM for the web. Every conversion runs entirely from the browser upload, so there's no desktop software to install.
Frequently Asked Questions
How do I convert a video to another format?
Drop your video into the upload box above (or click to browse), then pick the target format. The converted file downloads automatically when it's ready.
Is video conversion free?
Yes. Every video converter on MiConvert is free with no sign-up required. Upgrade to Pro only if you need larger files, batch conversion, or faster processing.
Will converting reduce my video quality?
We use high-quality encoding to keep your video looking sharp. If you specifically want a smaller file, use our compress tools to control the size.
Is there a file size limit?
Free users can convert files up to a generous limit. Sign in or upgrade to Pro for larger videos and batch jobs.
Are my uploaded videos safe?
Yes. Files are sent over a secure connection, processed privately, and deleted automatically shortly after conversion.
Why does MP4 play everywhere but MOV or MKV don't?
MP4 (H.264) is supported by essentially every browser, phone, and TV, while MOV is Apple's QuickTime format and MKV is a container many streaming apps and smart TVs don't recognize. Converting to MP4 is the safest choice for playback anywhere.
Can I get just the audio from a video file?
Yes. Choose an MP4 to MP3 (or AAC/WAV) conversion to extract the soundtrack without the video, useful for podcasts, lectures, or music pulled from a clip.
