## 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](https://www.ailovekit.com/dev/jwt-decoder/) for tokens.

- **API debugging** - decode response bodies quickly.

## Frequently Asked Questions

**Does it handle Unicode text?**

Yes - encoding uses UTF-8 byte conversion, so emoji and non-Latin scripts survive the round trip.

**Can I encode a file?**

Yes - use the file picker to convert any file to Base64 text, or decode Base64 back into a downloadable file.

**Is Base64 encryption?**

No. Base64 is encoding, not encryption - anyone can decode it. For real protection use Protect PDF or proper encryption.
