Best Base62 Encoder and Decoder Tools

Base62 encoding uses 62 characters (0-9, A-Z, a-z) to create compact, URL-safe strings. Unlike Base64, it needs no padding and avoids characters that require escaping in URLs. Base62 is popular for short URLs, database IDs, and API keys.

Here are the best free Base62 encoder and decoder tools you can use online—no installation, no signup.

1. everytools Base62 Encoder

Our Base62 Encoder encodes text to Base62 instantly. Paste your input and get the encoded string. Works in your browser—no data sent to servers. Copy output with one click.

2. everytools Base62 Decoder

The Base62 Decoder reverses the process—paste a Base62 string and decode it back to plain text. Ideal when you receive Base62-encoded data from APIs or short URLs.

Base62 vs Base64

Base64 uses 64 characters and often adds padding (=). Base62 avoids +, /, and padding, making it better for URLs and identifiers. For JSON or binary data in APIs, Base64 is more common. For short URLs and compact IDs, Base62 wins.
