Whitespace Remover

Seven modes, and the gap between two of them is a single character class. Remove All Spaces deletes the literal space and leaves your tabs and newlines standing. Strip All Whitespace takes everything, newlines included, and hands back one unbroken run. The Whitespace Remover keeps them apart because flattening a document into a single word is seldom what anyone meant.

The default is Collapse Spaces, which rewrites any run of 2 or more spaces as one and touches nothing else. Beside it sits a matched pair: Tabs → Spaces turns each tab into 2 spaces, and Spaces → Tabs turns any run of 2 or more spaces into a single tab. They are not exact inverses, which is worth knowing before you run one after the other.

A character count sits above the input and a green -56 chars removed badge over the output, so the size of the edit is visible before you copy it. One mode applies at a time and the tool never chains them. Your text stays in the page and no request is made.

Options, Mode by Mode

• Remove All Spaces strips U+0020 and nothing else, so indentation built from tabs survives it completely.
• Trim Lines trims each line on its own. Blank lines stay blank and the line count never changes.
• Collapse Spaces needs 2 adjacent spaces before it fires. A single space between words is untouched, which is what makes it safe on prose.
• Remove Blank Lines tests the trimmed length, so a line holding 12 spaces reads as blank and goes.
• Strip All Whitespace is the only mode that removes newlines. Use it on a hash or an API key that arrived wrapped across 3 lines.

What Happens When Tabs Meet Spaces

• Tabs → Spaces is fixed at 2 spaces per tab with no width setting, so a file written for a 4-space tab stop comes out half as deep.
• Running Spaces → Tabs afterwards will not restore it. Every run of 2 or more spaces becomes one tab, so 4 spaces of indent collapse to a single tab rather than two.
• Spaces → Tabs fires mid-line as well as at the start, which converts the padding inside an aligned table into tabs and breaks the alignment.
• A non-breaking space looks like a space but is not one. Collapse Spaces and Remove All Spaces walk straight past it, while Trim Lines and Strip All Whitespace both count it as whitespace and remove it.
• A carriage return is whitespace but not a newline here, so a Windows file loses its \r only under Strip All Whitespace, which removes the \n beside it too.
