FAQ
What is URL-safe Base64?
URL-safe Base64 uses - and _ instead of + and /, and omits padding. This makes it safe to use in URLs without encoding.
Can I encode files?
Yes, you can drag and drop files or use the file input to encode files to Base64.
What is auto-detect mode?
When enabled, the tool automatically detects if the input is Base64 and switches to decode mode, or encodes if it's plain text.
