Base64 Encode/Decode Tool
Encode plain text to Base64 or decode Base64 back to text.
This page is an editable estimator with realistic defaults so you can model your own situation in minutes.
Base64 encodes binary/text bytes into ASCII characters for transport.
Treat the result as a planning estimate and verify important numbers with the relevant official source before acting.

Base64 Encode/Decode Tool FAQ
Is this base64 encode/decode tool safe for sensitive data?
Use it for general planning and low-risk data. Do not paste production secrets, private keys, access tokens, customer data, regulated data, or confidential credentials into browser tools unless you have verified the environment and policy.
Are the outputs guaranteed for production systems?
No. Verify network, security, encoding, bandwidth, QR, and implementation details in your actual infrastructure, browser, device, scanner, and deployment environment.
Why might my result differ from a real system?
Real systems can differ because of routing rules, reserved addresses, protocol overhead, throttling, compression, encoding expectations, scanner quality, password policy, and platform-specific behavior.
