What's Base64 code?

Base64 is a base of 64 A printable character indicates the method of binary data. It is often used to transmit binary data in systems that require text data processing, as in Embedded pictures (Data URI), transmit attachments in e-mail or transmit complex data in URLs.

100% Local Processing

All your data are coded locally in the browser, never uploaded to any server, and privacy is guaranteed.

Cross Platform Compatibility

Perfectly supports all mainstream browsers such as Chrome, Firefox, Safari, Edge, without any plugins.

Support for Unicode

Full support is given to all Unicode characters, such as Chinese, Japanese, Emoji, etc., to ensure that the contents are not coded after decoded.

Common issues (FAQ)

Base64, is it encrypted?
Nope. Base64 It is a code that is designed to transmit binary data without encryption security. Anyone can get through Base64. Decoding tool restores the original data. Use encryption algorithms such as AES if you need to protect data.
Why does Base64 get bigger after code?
Base64 encoding converts raw data per 3 bytes to 4 character, so the number of coded data is usually about 33% higher than the original data.
