Frequently Asked Questions
How do I play and decode a Base64 video string?
Paste your Base64 encoded video Data URI (e.g. data:video/mp4;base64,...) into the input box. The tool decodes the video into an HTML5 player and enables one-click download of the .mp4 or .webm file.
Which video formats are supported?
Our player supports MP4 (H.264), WebM (VP8/VP9), and OGG video formats.
Can I embed Base64 video directly in an HTML page?
Yes, use '<video controls src="data:video/mp4;base64,..."></video>' to embed short animations or video clips inline.
Is there a recommended video size for Base64?
Due to Base64's 33% file size expansion, Base64 is best suited for short looping animations, hero clips, or test video streams under 10MB.
Is my video uploaded to any server?
No, all decoding and playback runs 100% locally in your browser memory.
How do I download the decoded video file?
Click 'Download Video File' to save the decoded video directly to your device.
