Question 1

Is my data sent to a server when decoding Base64?

Accepted Answer

No. Decoding is 100% client-side using WebAssembly. Only the decoded text (not your original Base64) is sent to our AI provider for the security audit, and only when you click Decode & Audit.

Question 2

Does Base64Fix support JWT tokens?

Accepted Answer

Yes. Base64Fix automatically detects JWT tokens, decodes the header and payload, and provides AI-powered analysis of algorithm, claims, expiry, and security warnings.

Question 3

What is URL-safe Base64?

Accepted Answer

URL-safe Base64 replaces + with - and / with _ and omits padding. Base64Fix handles both standard and URL-safe variants automatically.
