About Text Trim
Text Trim is a browser-based whitespace cleaning utility. It performs several operations on your text: first, it removes leading and trailing whitespace (spaces, tabs) from the entire text block; then it trims each individual line. Optionally, you can enable "Collapse multiple spaces to one" to replace runs of two or more consecutive spaces with a single space, and "Normalize line breaks" to convert all line ending styles (CRLF from Windows, CR from old Mac, LF from Unix) to a single consistent format (LF).
This combination of features makes Text Trim perfect for cleaning text pasted from web pages, PDFs, or rich-text editors where invisible formatting characters accumulate. It is also useful for developers who need consistent whitespace in configuration files, data imports, or code formatting.
How to Use Text Trim
- Paste or type your text into the Input area.
- Optionally check Collapse multiple spaces to one to merge consecutive spaces.
- Optionally check Normalize line breaks (LF) to standardize line endings.
- Click Trim. The cleaned result appears in the Result area, ready to copy.
Key Features
- Full trim — Removes leading and trailing whitespace from the text and each line
- Space collapsing — Optionally merges multiple consecutive spaces into one
- Line break normalization — Converts CRLF, CR, and mixed endings to LF
- Instant results — Processes text of any size in milliseconds
- Client-side privacy — No server uploads; your text stays in your browser
When to Use This Tool
- Cleaning text copied from web pages, emails, or PDFs with extra whitespace
- Standardizing line endings before committing code or configuration files
- Preparing data for CSV import or database insertion
- Removing invisible formatting characters from rich-text sources
- Tidying up code comments or documentation with inconsistent spacing
Technical Details
The trimming process works in stages: (1) the entire text block is trimmed of leading and trailing whitespace, (2) each line is individually trimmed of leading and trailing spaces and tabs, (3) if "Collapse" is enabled, consecutive space characters within each line are replaced with a single space using a regular expression, and (4) if "Normalize" is enabled, all line ending sequences (\r\n, \r, \n) are replaced with \n (LF). This multi-pass approach ensures thorough cleaning. All processing runs in JavaScript within your browser.
Conclusion
Text Trim is an essential cleanup tool for anyone working with text from diverse sources. With whitespace trimming, space collapsing, and line break normalization, it delivers consistently clean output in one click — all within your browser.
