Encode plain text to Base64 and decode Base64 back to text.
Base64 Encoder / Decoder
Encode plain text to Base64 or decode Base64 back to text.
Privacy note: conversion runs in your browser only. No data is sent or stored.
What Base64 Is (and Is Not)
Base64 is an encoding format, not encryption. It converts binary/text data into a text-safe representation for transport.
Common Use Cases
- Email attachments and MIME content.
- API payloads that include binary blobs.
- Tokens or metadata passed through URLs and headers.
Important Reminder
If data is sensitive, Base64 alone is not protection. Use encryption and secure transport (HTTPS/TLS) when needed.
