Base64 Encoder & Decoder - Text and Files
Encode text or files to Base64, decode Base64 back, and download binary results.
The Developer's Swiss-Army Encoding
Embedding images in HTML, stuffing payloads into URLs, or debugging API responses - Base64 is the universal bridge between binary and text. AiLoveKit's Base64 encoder/decoder handles both directions with full UTF-8 support, file uploads, and downloadable binary output - all computed locally in your browser, so tokens and payloads never touch a server.
Common Uses
- Data URLs - inline small images in CSS/HTML.
- JWT inspection - pair with JWT Decoder for tokens.
- API debugging - decode response bodies quickly.
