About BOM Checker
A Byte Order Mark (BOM) is an invisible unicode character (like EF BB BF) placed at the very start of a text file. While standard text editors ignore it, it strictly breaks PHP scripts, JSON deserializers, CSV importers, and Bash execution. Upload any file locally to strip its header and read its raw Hex byte signature to verify its cleanliness.
BOM Checker Features
- 100% Client-Side FileReader security
- Detects UTF-8, UTF-16 LE/BE, and UTF-32 BOMs natively
- Displays exact Hexadecimal Byte Sequences (Head)
- Crucial for debugging JSON parse errors
