Built for video files
Base64 increases size by roughly one third, so direct file upload is normally preferable for large videos.
No registration, watermark, queue, or server upload is required.

Base64 is ideal for text-only APIs, small embedded assets, test fixtures, and portable documents. It increases payload size, so external files are usually better for large public assets.
Frequently asked questions
Is Base64 practical for large videos?
Generally no. Base64 adds ~33% size overhead and loads entirely into memory. Use direct file upload for large video files.
Which video containers are supported?
Formats the browser can read locally, such as MP4, WebM, and MOV, up to 100 MB per file.
When should I use Base64 for video files?
Use it when a text-only channel or API must carry binary data, or when a small video files asset needs to live inside a self-contained document. Prefer separate files for large, cacheable public assets.
