Radix64: Base64 Encoder

Radix64 turns text, photos, and files into Base64 — and back — entirely on your iPhone, with no upload and no account. It's built for developers who need a data URI for CSS or HTML, anyone decoding a token, or someone who just needs a quick, clean Base64 encode or decode without hunting through a cluttered web tool.

Type or paste on either side and watch the other update instantly — encoding and decoding share one screen, so there's no mode to pick first. Import a photo or file to get its Base64 (or a ready-to-use data: URI), or paste Base64 back in to reconstruct and share the original file.

Included • Live, two-way text ↔ Base64 conversion • Standard and URL-safe variants, with or without padding • One-tap Data URI wrapping for CSS and HTML • Encode photos and files to Base64, decode Base64 back into a file • Recent conversion history

Radix64 Pro unlocks batch file and photo conversion plus unlimited, searchable history — a one-time purchase, no subscription.

Radix64 is a focused utility, not a bloated suite — open it, convert, done.
