Enobil Labs File Encoding Detector

Detect text file encodings, Byte Order Marks (BOM), and line ending formats locally in your browser

Why Use Our Encoding Detector?

🔒 Complete Local Confidentiality
Your code files, logs, and sensitive data sheets are parsed entirely locally in the browser memory. No server upload occurs.
✔️ Exact Line Ending Breakdowns
Flags mixed line endings by displaying exact counts for CRLF, LF, and CR control characters so you can identify layout corruption.
🚀 Advanced Encoding Heuristics
Analyzes byte sequences to differentiate between UTF-8 and ISO-8859-1, and detects UTF-16 null byte distribution frequencies.
📴 Offline Operation
Audits files without internet connectivity. Once the page is loaded, the entire detector runs completely offline.

Frequently Asked Questions

❓ Is my text file uploaded to any servers to analyze the encoding?

No. The entire file analysis, byte inspection, and encoding detection logic runs strictly in your browser using local HTML5 FileReader APIs. Your file content never leaves your machine.

❓ What text encodings are supported?

We support detection for UTF-8 (with or without BOM), UTF-16LE, UTF-16BE (with BOM or guessed via null-byte layouts), UTF-32LE, UTF-32BE, US-ASCII, and Windows-1252/ISO-8859-1 (Western European).

❓ What line ending formats does it audit?

The tool counts and displays occurrences of CRLF (Windows \r\n), LF (Unix/macOS \n), and CR (Classic Mac \r). If your file contains mixed line ending characters, it provides a breakdown so you can clean them up.

❓ How does it detect encodings without a BOM?

We run strict byte-sequence heuristics. For example, UTF-8 has structured bits for multi-byte characters; if all high-bit bytes conform to this standard, it is UTF-8. If they violate it, we fallback to ISO-8859-1. For UTF-16, we analyze high null-byte frequencies.
