What is Base64 encoding & decoding?

Base64 is a binary-to-text encoding scheme that represents binary data or text strings in an ASCII string format based on 64 distinct characters. It is widely used to ensure data remains intact without modification during transit over networks or systems that primarily handle text-based formats — email attachments, embedded web assets, and URL parameters among them.

The Chronicle Point Base64 utility lets you effortlessly encode plain text into Base64 format and decode strings back to their original readable state. It also automatically detects and parses ZATCA Phase 1 & Phase 2 TLV e-invoice QR data into clean, labeled fields — and now you can feed it a QR image directly, by uploading a file, dragging one in, pasting from clipboard, or scanning live with your camera. Everything runs client-side in your browser — nothing is ever uploaded to a server.
