Base64 and URL encoding, plus extractors for emails and URLs. Every operation runs in your browser — nothing is sent to a server.
Encode and decode Base64 and URL text, extract emails and URLs, generate slugs. Free online tools — instant and private.
Text is encoded as UTF-8 bytes first, so Café encodes correctly to Q2Fmw6k= rather than losing the accent.
The Base64 string is decoded to bytes and then read as UTF-8, so Q2Fmw6k= comes back as Café.
Reserved and unsafe characters are percent-encoded: a space becomes %20, & becomes %26 and / becomes %2F.
Percent-escapes are converted back to characters, with UTF-8 multi-byte sequences reassembled correctly.
Full URLs (http, https, ftp), protocol-relative //example.com links and bare www. or domain.tld forms are all detected.
Every address matching name@domain.tld is pulled out, including subdomains and multi-part endings such as .co.uk.
Accents are transliterated: é becomes e, ø becomes o and ü becomes u, so the slug stays pure ASCII.
