Encodings & Converters
Fast binary-to-text converters: Base64, Base64URL, Base58 (Bitcoin), Base32, Hex, and URL encoding. All tools run strictly inside your browser thread via the W3C Web Cryptography API with zero remote telemetry.
Base64 Encoder & Decoder
Encode plaintext into Base64 or decode Base64 into UTF-8 strings and binary byte arrays in your browser. Fast, bidirectional, and private.
Base64URL Safe Encoder & Decoder
Convert between standard Base64 and URL-safe Base64URL (- instead of +, _ instead of /, no = padding). Standard for JWT tokens and web URLs.
Base58 (Bitcoin/Solana) Encoder & Decoder
Encode and decode Base58 strings used across Bitcoin, Solana, and IPFS. Excludes confusing characters (0, O, I, l) to prevent human reading errors.
Base32 Encoder & Decoder
Encode and decode Base32 strings. Standard for TOTP two-factor authentication secret keys (Google Authenticator) and Tor onion addresses.
Base85 / Ascii85 Encoder & Decoder
Encode and decode Base85 (Ascii85) binary-to-text strings. Used in Adobe PDF files, Git binary patches, and btoa IPv6 representations.
Hex to String (ASCII/UTF-8) Converter
Convert raw hexadecimal byte sequences (0x48656c6c6f) into human-readable ASCII and UTF-8 strings client-side.
String to Hex Converter
Convert plain text and Unicode strings into continuous or space-separated hexadecimal byte sequences.
Hex to Binary Converter
Convert hexadecimal strings into 8-bit padded binary strings (0s and 1s) with byte grouping in your browser.
Binary to Hex Converter
Convert binary sequences (0s and 1s) into clean, compact hexadecimal strings client-side.
Binary to Text (ASCII) Converter
Convert 8-bit binary code (01001000 01101001...) into readable ASCII and UTF-8 characters in your browser.
Text to Binary Converter
Convert plain text and symbols into 8-bit binary bytes (0s and 1s) with space separation in your browser.
URL Component Encoder & Decoder
Percent-encode special characters in URLs (encodeURIComponent) or decode percent-encoded URLs into clean strings client-side.
HTML Entity Encoder & Decoder
Convert special HTML characters (&, <, >, ", ') into safe HTML entities (&, <, >) to prevent Cross-Site Scripting (XSS).
Punycode (IDN) International Domain Converter
Convert Internationalized Domain Names (IDN) with Unicode characters to ASCII Punycode (xn--...) and vice versa client-side.
Octal to Text & Text to Octal Converter
Convert base-8 octal byte sequences into readable text characters and convert plain text into octal notation in your browser.
About Encodings & Converters Architecture
Cryptographic operations in the Encodings & Converters suite are engineered to run client-side to prevent credential leakage. Whether processing private keys, password hashes, or security tokens, our platform guarantees that no sensitive bytes leave your workstation.
