Size Impact
Base64 encoding increases file size by ~33%
Converting video files to Base64 encodes the binary video data as ASCII text characters. This allows video files to be embedded directly in HTML, CSS, JavaScript, JSON, XML, or other text-based formats without requiring separate file requests.
The conversion process reads the video file as binary data, then encodes it using Base64, which represents the binary data using only 64 ASCII characters (A-Z, a-z, 0-9, +, /). This increases the file size by approximately 33% but makes the video universally compatible with text-based systems.

We support all major video formats including MP4, WEBM, AVI, MOV, FLV, MKV, and OGV. The tool uses the browser's native video capabilities, so format support depends on your browser.
Base64 encoding increases file size by approximately 33% due to the conversion from 8-bit bytes to 6-bit characters. For example, a 10MB video file becomes about 13.3MB when encoded.
For small video files (< 5MB), Base64 is often better as it reduces HTTP requests. For larger files, separate files are usually more efficient due to caching and streaming capabilities.
Yes, but consider the file size impact. Base64 is great for short clips, animations, and intro videos. For longer content, consider streaming or progressive loading instead.
