Encoders & Decoders
Professional encoding and decoding utilities for web developers, supporting Base64, URL encoding, HTML entities, and Quoted-Printable formats.
Base64 Encoder/Decoder
Convert text and binary data to/from Base64 format for email attachments, data URLs, API tokens, and embedding images in CSS/HTML.
HTML Entities Encoder/Decoder
Safely encode special characters (&, <, >, quotes) into HTML entities to prevent XSS attacks and display reserved characters in web pages.
Quoted Printable Encoder/Decoder
Encode text for MIME email transmission using Quoted-Printable format, ensuring 8-bit characters display correctly across email clients.
URL Encoder/Decoder
Safely encode URLs and query parameters by converting special characters to percent-encoded format for REST APIs and form submissions.
Hashing Tools
Comprehensive cryptographic hash generators for data integrity verification, password security, and digital forensics using industry-standard algorithms.
MD5 Generator
Generate MD5 hashes for legacy system compatibility, file integrity checks, and non-cryptographic checksums (not secure for passwords).
SHA-1 Generator
Create SHA-1 hashes for Git version control and legacy applications (cryptographically broken, not recommended for security).
SHA-224 Generator
Generate SHA-224 hashes (truncated SHA-256) for applications requiring shorter hash lengths while maintaining cryptographic security.
SHA-256 Generator
Create industry-standard SHA-256 hashes for maximum security in password storage, blockchain applications, and digital signatures.
SHA-384 Generator
Generate SHA-384 hashes (truncated SHA-512) for high-security applications requiring enhanced collision resistance.
SHA-512 Generator
Produce SHA-512 hashes offering the highest security level in the SHA-2 family for enterprise applications and long-term data protection.
CRC32 Generator
Calculate CRC32 checksums for fast error detection in file transfers, ZIP files, PNG images, and network protocols.
