Overview

Paste text for MD5 and SHA-256 digests plus Base64 and URL encode/decode. 100% local, zero permissions.

Hash Encoder is a minimal developer popup for checksums and encoding—without opening a website or digging through a multi-tool toolbox. Features: • Hash mode: MD5 and SHA-256 update as you type (standard single-pass, lowercase hex) • Base64 mode: encode or decode with UTF-8 support • URL mode: encode or decode with encodeURIComponent / decodeURIComponent • Copy any result with one click • 100% local processing — no network requests • Zero host permissions • Light and dark mode • English + Chinese (follows Chrome language) Use cases: API signature debugging, checksum verification, Base64 body inspection, URL query encoding. Not for password storage. MD5 is a legacy digest for compatibility checks only. Not in v1: file hashing, SHA-512, HMAC, context menu on selected text. Privacy: No data is collected, stored, or transmitted.
