About this tool

Encode text to Base64 and decode it back with full UTF-8 support, standard or URL-safe and optionally wrapped at 76 characters. Drop a file to get its Base64 or data: URI – with ready CSS and <img> snippets for images – or turn Base64 back into a file to download.

Files are converted locally and never uploaded.
