About Encoding Tools

Encode and decode text with Base64, URL encoding, HTML entities, and generate MD5 hashes — all in your browser. All tools are completely free, require no signup, and run entirely in your browser — your text is never sent to any server.

Encoding transforms text into formats that are safe to transmit, store, or embed in code. Base64 is used to embed binary data in JSON and email attachments. URL encoding makes text safe to pass in query strings. HTML entities prevent markup injection in web pages. MD5 hashing creates fixed-length fingerprints for verifying data integrity. These four tools cover the encoding operations developers reach for most.
