How to convert video online

  1. 1

    Upload your video

    Choose a file from your device or drag it into the editor. You can convert common formats like MP4, MOV, WebM, AVI, MKV, FLV, and M4V.

  2. 2

    Choose the new video format

    Pick the output format you want, then adjust resolution and quality if needed. This is useful when you need better compatibility, a smaller file, or a format a device or app accepts.

  3. 3

    Convert and download

    Start the conversion and download the new file when it finishes. The processing runs in your browser, so you can convert video without sending it to a remote server.

Understanding the settings

If you want the safest format for everyday playback, choose MP4 with H.264. It works well on phones, laptops, TVs, and most social platforms. WebM is a strong choice for web delivery because it can stay smaller at similar quality, while MOV is often preferred in Apple-focused workflows. Lower quality settings and smaller resolutions reduce file size, but if you keep the same codec and only change the container, conversion can be much faster and may avoid extra quality loss.

Best settings for common goals

General sharing

MP4 (H.264), CRF 23, keep the original resolution unless the source is larger than necessary.

This is the safest combination for playback compatibility, predictable quality, and sensible file size across phones, laptops, and social platforms.

Smaller web delivery

WebM (VP9), downscale to 720p if the source is larger, and keep a moderate quality target.

VP9 is more efficient than H.264, so it is a strong choice when bandwidth matters more than universal device compatibility.

Practical guidance

When to convert video instead of compressing it

Format conversion solves a different problem than size reduction. If a file refuses to play on a device, editor, or social platform, container and codec compatibility are usually the first things to fix.

  • Choose conversion first when the destination rejects the source format or codec.
  • Choose compression first when the file already works but is too large for upload or sharing.
  • Use both when you need a more compatible format and a smaller final file.

Compatibility, privacy, and limitations

Container vs codec

Changing a container is not always the same as changing the underlying codec. MP4 is broadly accepted, but the real playback result still depends on the video and audio codecs inside the file.

Best fallback format

If you need the safest everyday handoff, export to MP4 with H.264 video and AAC audio. It remains the most broadly compatible option across browsers, operating systems, and social platforms.

Privacy explanation

Video conversions often involve personal recordings, course captures, or internal business footage. Running the conversion in your browser avoids sending the full source file to an external conversion service.

Things to keep in mind

  • Very large 4K or long-duration conversions will still take time in a browser compared with native desktop software.
  • Switching to a less efficient codec or keeping a high resolution can make the output larger than the original file.
