How to remove BOM from text
Paste text into Input text or choose Upload for a text file. Remove BOM checks the first character for the invisible U+FEFF Byte Order Mark and removes it when present. The remaining text appears in BOM-free output, where you can select Copy or Download. The check covers the first character only.
Steps to remove a UTF-8 BOM
- Paste text into Input text, or select Upload to choose a text file.
- Review the cleaned value in BOM-free output.
- Select Copy to place the result on your clipboard, or select Download to save it.
What a UTF-8 BOM remover changes
Remove BOM reads the first character. When it is U+FEFF, the tool removes that one character and keeps the rest of the input in place. The marker is invisible in ordinary text, so this example writes it as [U+FEFF]:
Input: [U+FEFF]name,email
Output: name,emailLine breaks, spaces, punctuation, and other characters after the first position remain in the output. A BOM later in the text also remains.
Which files can you upload?
Select Upload and choose a .txt, .csv, .log, or .md file. The page also accepts text/plain files. The uploaded text is placed in Input text, where the same first-character check applies.
What happens when the input has no leading BOM?
Text without a leading U+FEFF returns unchanged. Empty input produces an empty output. If the input contains only a BOM, the output is empty, while Copy and Download remain available because the source contains one character.
What to do with the cleaned text
Review the result in BOM-free output. Select Copy to place it on your clipboard, or select Download to save the cleaned text as a file. The output contains the original text after the leading-character check.
Which text cleanup tool should you use?
Choose Remove BOM when the unwanted character is a leading U+FEFF. For other cleanup jobs, see Text Cleanup & Filter Tools. Use Remove Non-Printable Characters for non-printable characters generally, or choose Remove Special Characters when you need to choose which spaces, newlines, numbers, or extra characters to keep. Trim Whitespace handles leading, trailing, or repeated spaces.
