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. Use Convertr as a free H.264 video encoder online for MP4 output, or choose H264, H265/HEVC, AV1, VP9, ProRes, and common video containers with files up to 1 GB.

No signup Datoteke do 1 GB MP4 encoder workflows H.264 / H264 encoder output H264, H265, AV1, VP9, ProRes

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.

Or drop files here. Max file size 1GB.

Choose a file before converting.

What does a video encoder do?

A video encoder changes how a video is compressed. That can mean converting HEVC to H.264/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.
  • H.264 / H264 encoder free: use H.264 output when maximum device and browser support matters.

Free H.264 / H264 video encoder online

Choose H.264 or H264 output when your video needs the safest compatibility target for phones, browsers, smart TVs, messaging apps, editors, and social upload forms. The same encoder page also keeps broader MP4, H265/HEVC, AV1, VP9, and ProRes workflows available when you need a different codec target.

Can I use this as an H.264 / H264 encoder?

Yes. Upload your video, choose MP4 output, and use the available video settings to create an H.264/H264 MP4 for broad playback compatibility. If your source codec is already known, the codec-specific pages below can take you directly to AV1 to H264, HEVC to H264, VP9 to H264, and related workflows.

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.
