Frequently Asked Questions
What is Base64 encoding?
Base64 is an encoding scheme that represents binary data as ASCII text using 64 printable characters. It is commonly used in email, data URLs, and API authentication.
What is URL-safe Base64?
URL-safe Base64 uses '-' instead of '+' and '_' instead of '/' so the output can be safely included in URLs and filenames without percent-encoding.
Can I encode files?
Yes — upload a file and the tool converts it to Base64. You can also decode a Base64 string back to download the original file if it was a binary.
