Hash any text or file using SubtleCrypto for SHA family or a local MD5 implementation. Useful for checksums, deduplication, and integrity checks.
This hash generator (md5, sha-256) runs 100% in your browser. Nothing you paste, drop, or generate ever leaves your device - no analytics on your input, no uploads, no logs.
Broken for cryptographic use; fine for checksums.
Same browser-only philosophy. Free, no signup, no upload.
Generate v1, v4, and v7 UUIDs in bulk - copy or download as JSON.
Decode JWT header and payload locally - never sent to a server.
Encode and decode Base64 with full Unicode and URL-safe support.
Check password strength against length, classes, and common-password lists.
Beautify, validate, and minify JSON with sortable keys, exact error positions, and a one-click copy.
Validate JSON syntax with exact line and column for every error.
