// Encode or decode Base64 instantly. Supports standard and URL-safe Base64.
Encode
Converts plain text or binary data into a Base64 ASCII string safe for transport in JSON, HTML, or URLs.
Decode
Converts a Base64 string back to its original plain text or binary representation.
URL-safe
Replaces + with - and / with _ so the output is safe to use directly in URLs without percent-encoding.
// FAQ
What is Base64 encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. Commonly used in email, data URIs, and API payloads.
Is Base64 the same as encryption?
No. Base64 is encoding, not encryption. Anyone can decode a Base64 string - it provides no security. Do not use it to hide sensitive data.
When should I use URL-safe Base64?
Use URL-safe mode when the Base64 output will be included in a URL or filename. It replaces + with - and / with _ to avoid encoding conflicts.
