Whitespace Remover

Remove whitespace in various ways — leading/trailing, duplicate, or per-line.

Category: Text Tools

When to use?

Use it when text copied from the web or a PDF has stray spaces, or to tidy leading/trailing spaces in data from a database.

How to use

  • Paste the text into the input.
  • Choose the removal method: leading/trailing, duplicate, or all spaces.
  • Copy the cleaned result.

Input Explanation

Type or paste the text data you want to clean into the text area.

Calculation Basis

Using regular expressions, it trims edge spaces, collapses 2+ consecutive spaces, or removes all whitespace (spaces, tabs, line breaks) per the chosen option.

Usage Examples

  • Clean copied text - Remove stray spaces from text copied from the web or a PDF.
  • Clean data - Batch-remove leading/trailing spaces from database text.
  • Clean form input - Trim sign-up or search input to reduce errors.

Examples

  • " hello world " → trim: "hello world", collapse: "hello world"
  • Lines with ragged indentation → per-line trim aligns the start positions

Cautions

  • Results can vary by how line-break characters (LF/CRLF) are handled.
  • Results may differ from other tools depending on space and Unicode handling.

Guides

Removal options

There are several modes: trim (edges only), collapse (reduce consecutive spaces to one), and remove all whitespace.

Use for text cleanup

Useful when copied text has stray spaces, or for preprocessing before working with data. Pair with the duplicate remover or line sorter for cleaner results.

FAQ

What is the difference between removing all and trimming edges?

Trimming removes only the start/end spaces; removing all removes every space including line breaks and tabs.

Are tabs treated as spaces?

The collapse option unifies tabs into a single regular space.

Are line breaks removed too?

The remove-all option removes line breaks, making one line. Use another option to keep the line structure.

Are spaces between Korean characters handled?

Yes. Spaces are handled regardless of character type, so duplicate spaces between Korean are collapsed to one.
