How It Works
- Base64 encoding converts binary data into ASCII text using 64 safe characters (A-Z, a-z, 0-9, +, /)
- UTF-8 support allows encoding of any Unicode text, including emoji and non-Latin characters
- Auto-detect mode recognizes valid Base64 input and suggests decoding
- File upload reads any file and converts it to Base64 (useful for embedding images in CSS/HTML)
- 100% client-side, your data never leaves your browser, nothing is sent to any server
