Binary-Text Conversion Tool
This online binary converter provides bidirectional binary to text and text to binary conversion. Supports 30+ encodings including UTF-8, GBK, Big5, ideal for software development, data analysis, and cybersecurity applications.
- Real-time conversion: Instant results
- Precision decoding: Automatic BOM handling
- Error detection: Smart validation for invalid binary data
How to Use
Paste into the panel you need
The left panel converts binary to text, the right one converts text to binary. Both update as you type.
Choose the character encoding for that panel
Each panel has its own encoding selector. Pick the one the bytes were written in — UTF-8, UTF-16, GBK, Big5, Shift JIS, KOI8-R and around forty others.
Copy the result
Use the copy button on the output panel. Nothing leaves your browser.
Global Encoding Standards
Full support for Chinese encodings (GB2312/GBK/GB18030), Japanese (Shift_JIS), Korean (EUC-KR), plus Windows-1252 and ISO-8859 series for European languages.
Key Applications
- Binary data analysis in reverse engineering
- Cross-platform file encoding conversion
- Network packet parsing
- Legacy system data migration
Data Security Assurance
Featuring client-side processing technology, all conversions happen locally with zero server transmission and no cloud storage.
Cross-Platform Compatibility
Optimized for desktop, mobile, and tablet devices. Works seamlessly on Chrome, Firefox, Safari - essential tool for developers, cybersecurity experts, and data analysts.
Frequently Asked Questions
- Why does my binary input decode to the wrong characters?
- Two usual causes. Either the bits are not a multiple of eight — the converter reads them in groups of eight from the start, so one missing zero shifts every byte after it — or the encoding selector does not match the encoding the bytes were written in. Check both before assuming the data is corrupt.
- Why does the text-to-binary output have spaces between the bytes?
- Every byte is printed as exactly eight digits with a space after it, so you can still see where one byte ends and the next begins. Remove the spaces if you are feeding the result to another program.
- What happens to characters that are not 0 or 1 in the binary panel?
- They are stripped as you type. Spaces, newlines, commas and stray letters are all ignored, so you can paste binary straight from a log or a terminal without cleaning it first.
- Which encodings are supported?
- Around forty-five: UTF-8, UTF-16 in both byte orders, GBK, GB 18030, GB 2312, Big5, Shift JIS, EUC-JP, EUC-KR, ISO-2022-JP, CP866, KOI8-R and KOI8-U, Windows-1250 through 1258 and 874, most of ISO-8859, and Mac Roman and Mac Cyrillic. The list is in the selector on each panel.
