Hex / Decimal / Binary / Octal Converter

Convert numbers exactly between hexadecimal, decimal, binary, and octal.

Input

Private by design: your values never leave your device.

Output

Copy or download conversion as JSON.

Steps

Good to know

The Hex / Decimal / Binary / Octal Converter helps you convert hexadecimal, decimal, binary, and octal numbers directly in your browser. It is useful for development, debugging, API testing, documentation, and technical reviews when data needs to be checked quickly or moved into another format.

Typical searches for this page include hex to decimal, binary to decimal, decimal to hex, octal converter, and number base converter. Processing runs locally in the browser, so sample values, internal payloads, and technical snippets are not sent to a server. Watch prefixes such as `0x`, `0b`, and `0o`; without a prefix, decimal is often expected.

Typical use cases

API and payload debugging

Check hexadecimal, decimal, binary, and octal numbers from REST APIs, webhooks, logs, or browser developer tools before using it in tests, documentation, or production configuration.

Documentation and code review

Prepare data so it stays understandable and reproducible in pull requests, README files, tickets, and technical specifications.

Local inspection of sensitive data

Use the tool for internal examples, technical test values, or confidential fragments without copying them into external online services.

Tips for better results

Check the input format deliberately

Many issues come from wrong quotes, missing escapes, unexpected whitespace, or copied prefixes. Check the input first before using the result further.

Validate the result in context

Formatting and conversion do not replace domain validation. For data migrations, security values, or production configuration, always check what the result means.

How it works

Step by step

  1. 1

    Paste data

    Paste hexadecimal, decimal, binary, and octal numbers into the input field or choose a local file when the tool supports file import.

  2. 2

    Adjust options

    Choose format, variant, indentation, or output options as needed for your target system.

  3. 3

    Use the result

    Copy the output into code, tests, documentation, or configuration and review critical values before use.

Features

Runs locally in the browser

Inputs are processed on your device and are not sent to a server for processing.

For developer workflows

Useful for API data, configuration files, logs, test data, and technical documentation.

Instantly reviewable result

The result is visible immediately and can be copied or downloaded for the next step.

Frequently asked questions

Is data uploaded when using the Hex / Decimal / Binary / Octal Converter?

No. Processing runs locally in the browser. Inputs are not transferred to Xoricon or another server.

Can I use the result directly?

Yes, for tests, examples, and documentation. For production data, also validate the result in the target system.

Why can an input fail?

Common causes are a wrong format, missing escapes, invalid characters, incomplete data, or a variant that does not match the expected standard.
