# Base64 & URL encoder

Encode and decode Base64, URL-safe Base64 and percent-encoded URLs, with full Unicode support.

## How it works

Base64URL swaps + and / for - and _, and drops the padding, so it’s safe in URLs and JWTs. URL encoding escapes characters that have meaning in URLs.

## Questions

### Is Base64 encryption?

No. Anyone can decode it.

### Why is my output longer?

Base64 makes data about a third larger.
