What is Base64 encoding?

Base64 is a binary-to-text encoding scheme that represents binary data using only 64 ASCII characters. It's commonly used to embed images in HTML/CSS, encode email attachments, and pass data in URLs.

How do I encode a file to Base64?

Upload your file or paste your text into ZapFile's Base64 Encoder and click Encode. The tool instantly produces the Base64 string you can copy and use.

Does Base64 encoding compress data?

No. Base64 encoding actually increases data size by approximately 33%. It's used for compatibility, not compression.
