🔗Base64URL Converter
Standard Base64 uses the characters `+`, `/`, and `=` which can cause issues when used in URLs or filenames. Base64URL is a standard modification that replaces `+` with `-`, `/` with `_`, and removes the trailing `=` padding. This utility makes it easy to convert between plain text and this URL-safe format, which is essential for working with JSON Web Tokens (JWT) and other modern web protocols.
Frequently Asked Questions
How is Base64URL different from Base64?
Base64URL modifies the standard Base64 alphabet to be safe for use in URLs and filenames. It replaces character 62 (`+`) with `-` and character 63 (`/`) with `_`. It also omits the padding character (`=`).
When should I use this?
Use this tool when working with JWTs (JSON Web Tokens), OAuth flows, or passing binary data via URL query parameters, where standard Base64 characters might be misinterpreted by the browser or server.
