Base64 is an encoding scheme that converts binary data into ASCII text using 64 characters (A–Z, a–z, 0–9, +, /). It's used to transmit binary data over text-based systems like email and URLs.

What is URL-safe Base64?

URL-safe Base64 replaces + with - and / with _ so the encoded string can be safely used in URLs without percent-encoding.

Can Base64 encode images?

Yes. Base64 can encode any binary data including images. However, this tool encodes text only — for image Base64, use a dedicated image-to-Base64 tool.

Is Base64 a form of encryption?

No. Base64 is encoding, not encryption. It obfuscates data but provides no security — anyone can decode it instantly.
