Frequently Asked Questions

What video formats can I convert?
You can convert between MP4, WebM, MKV, MOV, AVI, GIF, and many more. The tool supports most common video and audio formats.
Is my video uploaded to a server?
No. All conversion happens entirely in your browser using WebAssembly. Your files never leave your device, ensuring complete privacy.
What is the maximum file size?
There is no hard limit, but the maximum size depends on your device’s available memory. Files over 2GB may cause performance issues on some systems.
Can I convert videos for social media platforms?
Yes. We offer presets for YouTube, TikTok, Instagram, and Facebook that automatically set the correct resolution, aspect ratio, and codec settings.

How to convert videos online quickly

Upload your file, choose the output settings, and process it directly in your browser. Because conversion happens on your device, your source files never leave your machine.

  • Use MP4 (H.264) for broad compatibility across devices and social platforms.
  • Lower bitrate and resolution together to reduce file size for sharing.
  • Test a short clip first when using aggressive compression settings.

Good To Know

  • These tools improve and reformat the video data you already have, but they cannot invent missing real detail that was never captured in the original file.
  • Frame-rate changes (for example 30fps to 60fps) can make motion smoother, but on low-motion scenes the output may still look very similar.
  • Final results depend on source quality, scene motion, and playback screen size, so short test clips are the best way to pick perfect settings.
