Frequently asked questions
What is Base64 encoding used for?
Base64 converts binary data (like images or files) into plain ASCII text so it can be safely embedded in places that only support text - email attachments, JSON payloads, data URIs in CSS/HTML, and API requests.
Is Base64 the same as encryption?
No - Base64 is an encoding scheme, not encryption. It's fully reversible by anyone with no key required, so it should never be used to protect sensitive data.
Why did decoding my text produce an error or garbled output?
This usually means the input wasn't valid Base64 to begin with (missing padding characters, extra whitespace, or it was never actually Base64-encoded) - double check you copied the complete encoded string.
