Professional-grade encryption, hashing, encoding, and audio conversion — all running directly in your browser. No servers. No accounts. No data leaves your device.
Advanced Encryption Standard with GCM, CBC, and CTR modes. Supports 128, 192, and 256-bit keys. NIST-approved.
Asymmetric encryption with OAEP and PKCS#1 padding. Generate key pairs from 1024 to 4096 bits.
Generate cryptographic hashes with SHA-256, SHA-512, MD5, and more. Verify data integrity instantly.
Hash-based Message Authentication Code for verifying message integrity and authenticity with a shared secret.
Adaptive password hashing with configurable work factor. Industry standard for secure password storage.
Encode and decode text or binary data using standard Base64 or URL-safe Base64 format.
Convert text to hexadecimal representation and back. Essential for binary data inspection.
Percent-encode strings for safe use in URLs and query parameters. RFC 3986 compliant.
Inspect and decode JSON Web Tokens — header, payload, and expiry. No signature verification (client-only).
Convert between MP4, AVI, MKV, MOV, WebM, FLV, 3GP, and GIF. Change resolution, quality, and FPS. All in-browser with FFmpeg.wasm.
Convert any video clip into an animated GIF with custom frame rate and resolution. Perfect for sharing short clips without audio.
Convert audio between MP3, WAV, FLAC, AAC, OGG, OPUS, M4A, and AIFF. Extract audio from video files too.
Extract audio tracks from MP4, MKV, MOV, AVI, and WebM video files without any quality loss.
Data Encryption Standard — CBC, ECB, CFB, OFB modes. Legacy compatibility tool. Not recommended for new projects.
Applies DES three times per block — stronger than DES but deprecated by NIST in 2023. For legacy system compatibility only.
Generate cryptographically secure passwords with custom length, character sets, and strength meter. Bulk generate up to 100 passwords at once.
Generate memorable multi-word passphrases — easier to remember than random passwords and often stronger.
Every operation runs entirely in your browser using the Web Crypto API and WebAssembly. No data is sent to any server. No analytics. No logging. Your secrets stay yours.
