📖 Description

Beyond the universal Base64, different scenarios have higher demands for character "readability" and "specificity":

Base32: Uses only uppercase letters and numbers $2-7$, case-insensitive. Commonly used for key exchange in Google Authenticator.
Base58: The standard for blockchain (Bitcoin). Removes easily confused characters (like 0, O, I, l), effectively preventing input errors during address copying or manual transcription.
Base62: The preferred choice for Short URLs. Includes 0-9, a-z, A-Z, often used to compress long IDs into concise URL paths, and contains no special symbols.
Base100: Visual steganography/fun encryption. Maps data to Emoji symbols, suitable for conveying information in a "fun and cryptic" way on social media.

This site's tool integrates multiple algorithm libraries, providing you with a one-stop service for encoding and decoding:

Base32: Strictly adheres to the RFC 4648 standard.
Base58: Supports various alphabet orders like Bitcoin (BTC), Flickr, and Ripple.
Base62: Supports the common 0-9a-zA-Z ordering, ensuring consistency in short-link logic.
Base100: Full mapping conversion based on Emoji.

Input Detection: Automatically checks the validity of input during decoding (e.g., immediate error alert if Base58 text contains the number 0).
Automatic Whitespace Removal: Automatically trims spaces or line breaks from the input content, preventing decoding failures due to formatting issues.

Encode: Converts raw text (UTF-8) or hexadecimal data into the specified Base sequence.
Decode: Restores complex Base sequences to human-readable original text.

Data Never Leaves: All encoding and decoding algorithms run locally in your browser. Your sensitive keys, private keys, or steganographic content are never uploaded to a server, ensuring absolute privacy and security.

Encoding Type	Characteristics	Typical Application Scenarios
Base32	All uppercase, easy to dictate	2FA two-step verification, TOTP keys.
Base58	No confusing characters	Bitcoin addresses, blockchain transaction IDs.
Base62	Alphanumeric only	Short URLs, internal system short ID compression.
Base100	All Emoji symbols	Fun social interactions, visual information hiding.

Select Algorithm: Choose your required encoding type (e.g., Base58) from the navigation or dropdown.
Input Content: Paste the raw text (for encoding) or encrypted sequence (for decoding) into the left input box.
Execute Operation: Click the "Encode" or "Decode" button.
View Result: The result will be displayed instantly in the right/bottom output box.
One-Click Copy: Click "Copy" when satisfied to directly apply it to your development environment or chat window.

All-in-One: One page solves all special base conversions, eliminating the need to search for multiple single-purpose tools.
Developer-Friendly: Perfectly handles various special characters and supports multi-line batch conversion.
Completely Free: No registration required, unlimited usage. A productivity multiplier for technical exploration and daily development.
Clean Interface: No pop-up distractions, focused on processing logic.
