What is a Base62 Encoder/Decoder?
A Base62 Encoder/Decoder is a tool that converts data into Base62 format and back. Base62 uses 62 characters: uppercase letters (A–Z), lowercase letters (a–z), and numbers (0–9) to represent data as text.

How does it work?
Base62 works similarly to Base64, but without symbols like + or /. Each character represents a value in base 62, which allows binary data or numbers to be encoded as compact text. This makes Base62 ideal for scenarios where text needs to be URL-friendly or shorter than Base64, while still being reversible.

What is it used for?
Base62 is commonly used to:

• Encode numeric IDs for short URLs or tracking links
• Convert binary data to a compact text format
• Generate URL-safe, readable tokens or keys
• Store or transmit data in systems that support only alphanumeric characters

Like Base64, Base62 is not encryption; it only encodes data so it can be represented as text and easily decoded back to its original form.
