Video encoder online

Free Online Video Encoder

Encode video online when you need to transcode, re-encode MP4, change codecs, or make a video easier to play, upload, edit, or share. Convertr supports MP4, H264, H265/HEVC, AV1, VP9, ProRes, and common video containers with files up to 1 GB.

Encode or re-encode a video

Upload a video, choose MP4 or another output format, then adjust codec, bitrate, resolution, or other settings before conversion. The encoder starts on a compatible worker immediately after upload.

What does a video encoder do?

A video encoder changes how a video is compressed. That can mean converting HEVC to H264 for compatibility, re-encoding MP4 with a different bitrate, changing AV1 or VP9 into MP4, or turning a ProRes editing export into a smaller delivery file.

Encoding, transcoding, and re-encoding are often used for the same practical goal: create a video file that fits the device, browser, editor, upload form, or sharing workflow you need.

If you only need a different file extension, start with the video converter. If you know the codec problem, choose one of the exact encoder pages below.

Common encoder searches

  • Online video encoder: choose a format and codec for playback or upload compatibility.
  • MP4 encoder: create a standard MP4 file from codec-heavy sources like HEVC, AV1, VP9, or ProRes.
  • Re-encode MP4: keep MP4 output while changing video codec, audio codec, bitrate, or resolution.
  • H264 encoder free: use H264 output when maximum device and browser support matters.

Choose a codec encoder

These dedicated pages keep generic encoder intent separate from exact codec pair intent, so you can pick the workflow that matches your source video and output target.
