Anslation Encoder Lab encodes and decodes Base64, standard or URL-safe, for text in any language. It decodes a pasted data URL and turns files up to 5 MB into Base64 or a data URL. It percent-encodes a part of a URL or a whole URL (with spaces as + for form data if you like), and splits a URL into its parts with decoded query parameters. It computes SHA-1, SHA-256 and SHA-512 of text, or of a file up to 200 MB, with the browser’s own Web Crypto. It decodes a JWT’s header and payload and shows when it was issued and when it expires. It does not verify signatures, and says so. Your last Base64 and URL inputs are kept in your browser; hash input and tokens are never saved.
