Encoding tools

Encode and decode Base64, URLs and HTML entities. Every tool runs in your browser, so nothing you add is uploaded.

Base64

Turn text or files into Base64, and decode Base64 back into text, images or other files.

Base64 Decode

Converts Base64 back into readable text, or into the original file (such as an image or PDF) when it is not text.

Base64 Encode

Converts text or a file into Base64, with URL-safe and line-wrapping options.

URL & HTML

Make text safe for web addresses and HTML, or read encoded links and entities.

URL Decode

Turns percent-encoded URLs and query strings (%20, %C3%A9…) back into readable text.

URL Encode

Percent-encodes text for use in URLs and query strings, handling spaces, symbols and any language.

HTML Entities

Escapes text for safe use in HTML (< becomes &lt;) and decodes entities like &eacute; back into characters.

About Encoding tools

Convert text and files into the encoded forms used on the web and back again: Base64 for email attachments, data URLs and APIs; percent-encoding for links and query strings; and HTML entities for showing code safely on a page. Everything is converted instantly in your browser.

Frequently asked questions

Is encoding the same as encryption?

No. Encodings like Base64 and URL encoding can be reversed by anyone instantly. They make data safe to transport, not secret.
