Base64 Encode API Tokens and Bearer Credentials

Your files never leave your browser. All processing happens client-side via WebAssembly.

Many APIs require Base64-encoded tokens in authorization headers. PDFJolt encodes your API tokens, JWT payloads, and bearer credentials instantly without sending them to any server.

Paste your token or key and get the Base64 string for your Authorization header. Decode existing tokens to inspect claims and expiry. Everything happens in your browser — zero exposure risk.
