What does File to Base64 do?
Converts files into Base64 strings. Base64 represents binary data as text (A-Z, a-z, 0-9, +, /). Useful for embedding in JSON, HTML, or transmitting over text-only channels.
What is it used for?
- APIs: Send binary data as Base64 in JSON payloads
- Data URIs: Embed media in HTML/CSS (e.g.
data:audio/mp3;base64,...) - Storage: Store binary in text-only databases or configs
- Transmission: Pass binary through systems that only accept text
