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.

MP4 Codec Converters

Use the codec hub when you already know the source codec and need the exact MP4 workflow.

Video konvertor

Use the video converter when your main choice is output format, such as MP4, MOV, WebM, AVI, or MKV.

Video Compressor

Use compression controls when your goal is a smaller file rather than a different codec or container.
