About Base64 Encoding
Base64 encodes binary data as ASCII text using 64 printable characters (A–Z, a–z, 0–9, +, /). It is commonly used to embed binary assets in JSON, XML, HTML, or email payloads where binary data cannot be transferred directly.
File Upload
Switch to Encode mode and click Upload to convert any binary file — images, PDFs, archives — into a Base64 string. The encoded result can be used directly in data: URIs or API payloads.
