Understanding Base64 Encoding

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used when there's a need to encode binary data that needs to be stored and transferred over media designed to deal with textual data.

Web Development

Embed images directly in HTML/CSS using data URLs to reduce HTTP requests.

Data Transmission

Send binary data over text-only protocols like JSON, XML, or email.

FAQ

What is Base64 used for?

To encode binary data (images, files) into ASCII text for transmission over text-based protocols.

Does Base64 increase file size?

Yes, by about 33% because every 3 bytes become 4 characters.

Is Base64 secure?

No, Base64 is encoding, not encryption. Anyone can decode it.

What does "=" at the end mean?

It's padding. Base64 works with groups of 3 bytes; padding is added when the input length isn't a multiple of 3.
