Encode any file to a Base64 string or data URI.
Processed locally in your browser. Your file is never uploaded.
Overview
Encodes any file — images, fonts, small documents — into a Base64 string or a ready-to-use data: URI you can embed directly in HTML or CSS.
How to use it
- 1Drop a file.
- 2Copy the Base64 string or the full data URI.
- 3Toggle between the two formats.
Tips
- Data URIs are convenient for small assets, but embedding large files this way bloats HTML/CSS and skips browser caching — keep it to small icons or fonts.
