About this app

Base64 / Hash Toolbox is a fast, no-nonsense developer utility for everyday encoding and hashing tasks. All conversions run 100% on your device — your text and files are processed locally and never uploaded.

▍BASE64
• Encode and decode UTF-8 text in real time as you type
• Standard and URL-safe alphabets
• Whitespace-tolerant decoding (paste freely)
• Smart auto-detect: paste a Base64-looking string and the app suggests "Decode?" with one tap

▍HASH
• MD5, SHA-1, SHA-256, SHA-512
• Lowercase or uppercase hex output
• Instant digests as you type

▍FILES
• Pick any file to Base64-encode or hash it
• Large files are streamed efficiently in the background — no freezing, no memory blow-ups

▍HISTORY, FAVORITES & STATS
• Every conversion you save is kept locally (most recent 50)
• Tap an entry to instantly reuse its settings and input
• Star the ones you use often and filter to favorites
• See running per-tool counts at a glance
• "Clear all" keeps your favorites safe

▍POLISHED EXPERIENCE
• Clean Material 3 interface with dynamic color (Android 12+)
• Light and dark themes
• English and Korean
• One-tap copy and share for any result
• Your text and options are restored even after the app is closed

▍PRIVACY & ADS
• Your conversion data stays on your device — nothing is sent to a server
• The app is ad-supported: it shows a banner and an occasional app-open ad, which require a network connection
• Prefer an ad-free experience? A one-time "Remove ads" in-app purchase removes all ads for good

Perfect for developers, QA engineers, students, and anyone who regularly works with Base64 strings or cryptographic checksums. Lightweight, instant, and easy to use.
