How to Convert Video Formats Free — MP4, WebM, AVI, MOV

Why Convert Video Formats?

Not every platform accepts every format. WebM works great on the web but not in PowerPoint. AVI is legacy but still common in older workflows. MOV is Apple's format and can be troublesome on Windows. MP4 with H.264 is the universal format — if you need maximum compatibility, convert to MP4.

How to Convert Video in Your Browser

1. Open the Convert Video tool
2. Upload your video file in any supported format
3. Select the output format (MP4, WebM, AVI, MOV)
4. Click Convert and download the result

Conversion happens on your device using browser-based processing. No file uploads, no server queue.

Which Format Should You Choose?

• MP4 (H.264) — Best for sharing, social media, email. Plays on every device and platform.
• WebM (VP9) — Best for web embedding. Smaller files at equivalent quality. Not supported in Safari on older devices.
• AVI — Legacy format. Only convert to AVI if the receiving software specifically requires it.
• MOV — Apple's container format. Best for Final Cut Pro or Apple-specific workflows.
