About URL Safe Base64
Standard-Compliant Base64 for the Web
Standard Base64 contains characters that break URLs. Our tool uses the Base64URL standard, ensuring your encoded data can be passed safely through browser address bars and API endpoints.
- No More Broken Links: Replaces URL-hostile characters according to RFC 4648.
- Stripped Padding: Optionally removes "=" padding for cleaner, URL-compatible output.
