What is a Base64 to video decoder?
A Base64 to video decoder converts encoded video bytes back into a playable and downloadable video file. It supports data URLs and raw Base64 for MP4, WebM, and OGG video payloads.
How to use it
- Paste a Base64 video string or video data URL.
- Use auto-detect or choose the expected video MIME type.
- Preview and download the decoded video.
Example
Input: data:video/mp4;base64,AAAAIGZ0eXBtcDQy...
Output: a downloadable MP4 file.
Common mistakes
- Raw Base64 may not include the video format.
- Very large videos are a poor fit for Base64.
- A truncated payload may decode into a broken video file.
