Base62 Encoder / Decoder

Encode integer IDs into Base62 format or decode back to original values, ideal for URL shortening, and systems requiring alphanumeric character sets.

Integer Base Converter
Convert numbers between different bases, including decimal, binary, tenary, octal, hexadecimal, and base62.
Base64 Encoder / Decoder
Encode text data to Base64/Base64URL or decode back to original form, ideal for URL params, data transmission, and complex JSON/XML payloads with UTF-8 support.
Base32 Encoder / Decoder
Encode text into Base32 format or decode back to original form, ideal for case-insensitive encoding, and secure data transmission requiring human-readable formats.

How to Use Base62 Encoder?

  1. Select the “Encode” tab.
  2. Enter the text you wish to encode in the plain text box.
  3. The corresponding encoded text will automatically appear in the output box.

How to Use Base62 Decoder?

  1. Select the “Decode” tab.
  2. Enter the Base62 encoded string in the Base62 encoded text box.
  3. The system will automatically determine the encoding format and display the decoded string in the output box.

What is Base62?

Base62 is an encoding scheme that represents data in a compact, human-readable format. It is particularly useful in scenarios such as URL shortening, generating unique identifiers, and ensuring that the encoded data consists solely of printable characters. This makes it safe for use in web addresses and filenames.

Principle and Implementation

Base62 utilizes 62 distinct characters from the following set: 0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz.

These characters are chosen for their alphanumeric nature and readability, making them suitable for URLs and filenames without issues from special characters (like +, /, and = in Base64 encoding).

What is Base62 Used For?

Base62 encoding is widely used in various scenarios due to its compactness, readability, and URL-friendly nature. Here are some specific examples of its applications:

URL Shortening Services

Base62 is commonly used in URL shortening services like Bitly or TinyURL. By encoding long URLs into a compact Base62 string, these services generate short, easy-to-share links. For example, a long URL like https://www.example.com/page?id=12345 can be shortened to something like https://bit.ly/3d7, where 3d7 is a Base62-encoded string.

Generating Unique Identifiers (UIDs)

Base62 is ideal for creating unique identifiers in systems like databases, distributed systems, or APIs. For instance, a database might use Base62 to generate a short, unique ID like L5HG for a new record instead of a long numeric or hexadecimal value. This ensures the ID is both compact and human-readable.

Distributed Systems and Microservices

In distributed systems, Base62 can be used to generate unique session IDs, transaction IDs, or request IDs. For example, a microservice might generate a Base62-encoded request ID like qW3eRt to track and log transactions efficiently.

By leveraging Base62’s compact and readable format, these applications benefit from efficient data representation, improved user experience, and compatibility with web-based systems.
