🔢 Base64 Encoder / Decoder
Encode text to Base64 or decode Base64 back to text.
Practical guide
How to use Base64 Encoder
Encode text to Base64 or decode Base64 back to readable text. Useful for testing APIs, data URLs, tokens and simple encoding workflows.
Common uses
- Encode text for APIs
- Decode Base64 strings
- Inspect encoded payloads
- Create data URI fragments
Good practice
Remember that Base64 increases size and provides no secrecy. Decode unfamiliar payloads as text first and do not execute decoded scripts or files you do not trust.
Data handling
Base64 can be reversed instantly. Never use it as a replacement for encryption when data contains credentials or personal information.
Frequently asked questions
What is Base64?
Base64 is an encoding format that represents binary or text data using a safe ASCII character set.
Is Base64 encryption?
No. Base64 is encoding, not encryption. Anyone can decode it.
Why use Base64?
It helps transmit data through systems that expect text-safe characters.
