Frequently Asked Questions
What is Base64 encoding?
Base64 is an encoding scheme that converts binary data into ASCII text format, making it safe to transmit data over text-based protocols.
Does Base64 encoding compress data?
No, Base64 actually increases data size by about 33%. It's used for safe transmission, not compression.
Is Base64 encoding secure?
Base64 is not encryption - it's easily reversible. Use it for encoding, not for security purposes.
Can I encode any type of file?
Yes, Base64 can encode any binary data including images, documents, audio, and video files.
