About this tool

The tool returns a Base64 string, an optional data URI, and a metadata card so you can confirm the encoded file is the one you intended.

Gotchas

Base64 output can be much larger than the original file. Use it for small assets or workflows that specifically require inline text.

Choose plain Base64 or data URI based on the destination. A data URI includes the media type prefix; plain Base64 does not.
