Frequently Asked Questions
What is Base64 encoding?
Base64 is a binary-to-text encoding scheme that represents binary data as ASCII text. It converts each 3 bytes of binary data into 4 printable ASCII characters.
Why encode images as Base64?
Base64-encoded images can be embedded directly in HTML, CSS, or JSON without separate file requests. This is useful for small icons, email templates, and API payloads.
Does Base64 encoding increase file size?
Yes, Base64 encoding increases the data size by approximately 33% due to the encoding overhead. For large images, using separate files is more efficient.
