Encoding tools
Base64 and URL encode/decode — text in, text out, computed entirely in your browser.
- Base64
Encode and decode, with a URL-safe alphabet option.
- URL encoder
Percent-encode components or whole URIs, and back.
- Image ⇄ Base64
Image files to data URLs and back — format read from bytes, dimensions decoded, nothing re-encoded.
