Mini Slug Formatter

Tired of juggling five different websites just to encode a Base64 string or generate a SHA-256 hash? Mini Slug Formatter puts every developer text transform you actually use into one fast, offline pocket tool — no ads, no accounts, no clipboard sent off to some random server.

Paste in raw text, a URL, or a snippet of code, pick your transform, and watch the output appear instantly. Copy it back out or share it with one tap. Everything runs locally on your device the moment you type — there's no "convert" button to wait on and no network request in sight.

HERO INTERACTION

Open the app, tap a category — Base64, URL, Hex, ROT13, or Hash — and start typing or paste from your clipboard. The transformed result appears live in the output panel below as you type, with a single tap to copy or share it wherever you need it next.

KEY FEATURES

• Bidirectional Base64 encoding and decoding with a padded-output toggle
• URL percent-encoding and decoding, including form-urlencoded (+) space handling
• Hexadecimal encode/decode with uppercase and 0x-prefix formatting options
• Classic ROT13 Caesar-shift transform for quick, reversible text obfuscation
• MD5, SHA-1, and SHA-256 cryptographic hash generation from any input text
• Live transform-as-you-type — no separate "convert" button required
• One-tap clipboard paste and auto-paste-on-launch preference
• One-tap copy and native share sheet for any transformed output
• Local history of your last 20 transformations for quick reuse
• Save favorite transforms as reusable presets
• Guided onboarding quiz that tailors default behavior to how you actually work
• Dark Amber, true AMOLED black, and light/system theme options

HOW IT WORKS

Mini Slug Formatter is built around a simple, fast loop:

• Choose a transform category from the top row — Base64, URL, Hex, ROT13, or Hash
• Type, paste, or auto-paste text into the input panel
• Read the instantly transformed result in the output panel below
• Toggle format options like padding, uppercase hex, or the 0x prefix as needed
• Copy the result to your clipboard or share it directly to another app
• Revisit past conversions anytime from the History tab, or save frequent ones as Presets

Every operation happens the instant you type — there's no waiting, no spinner, and no round trip to a server.

PERFECT FOR

• Developers who need a quick Base64 or hex conversion without opening a browser
• QA engineers verifying URL-encoded query parameters on the go
• Anyone generating MD5, SHA-1, or SHA-256 checksums to verify file integrity
• Students learning about encoding schemes and classic ciphers like ROT13
• Security-conscious users who don't want to paste sensitive strings into a website
• Anyone who wants a fast, distraction-free utility that just works offline

PRIVACY & TRUST

All transformations are performed entirely offline and locally inside sandboxed system storage. No network connections are initiated, no clipboard content ever leaves your device, and no telemetry or analytics are collected. Your history and favorite presets remain stored locally on your device only, and can be cleared anytime from Settings.

Mini Slug Formatter has no accounts, no logins, and no ads — just a fast, private encoder that respects your time and your data. Download it today and keep every Base64, URL, Hex, and hash conversion exactly where it belongs: in your pocket.
