Remove extra spaces, tabs and blank lines from text

Whitespace Cleaner tidies up messy text by removing the invisible clutter that creeps in when you copy content between apps, spreadsheets, PDFs and web pages. With independent toggles you can trim leading and trailing spaces on every line, collapse runs of multiple spaces into one, delete empty and whitespace-only lines, strip trailing spaces, and convert tabs into spaces. Turn on just the operations you need and the cleaned result appears instantly, ready to copy or download.

Stray whitespace is more than a cosmetic nuisance. It breaks code indentation, misaligns CSV columns, defeats exact-match searches, and quietly prevents duplicate detection from working. A line that looks identical to another can differ by a single trailing space, and that difference ripples through everything downstream. Cleaning whitespace produces consistent, predictable text that behaves the same in every editor, database and script you paste it into.

The cleaner only ever touches spacing characters — your actual words, punctuation and line content are left exactly as written, making it a completely non-destructive way to normalize formatting. Everything runs locally in your browser, so nothing is uploaded or stored and your content stays private. Before-and-after statistics show how many characters and lines were removed, so you can see the impact of each cleanup at a glance.

Features at a glance

Frequently asked questions

What kinds of whitespace can this tool remove?

It can trim leading and trailing spaces from each line, collapse runs of multiple spaces into a single space, delete empty and whitespace-only lines, remove trailing spaces at the end of lines, and convert tab characters into spaces. You choose exactly which operations to apply with individual toggles.

Why does invisible whitespace cause problems?

Stray spaces and tabs break code indentation, cause CSV columns to misalign, defeat exact-match searches, and make duplicate detection fail. Cleaning whitespace produces consistent, predictable text that behaves the same everywhere, which is especially important when copying content between apps, spreadsheets and editors.

Will it change the words in my text?

No. The cleaner only touches spacing characters — spaces, tabs and blank lines. Your actual words, punctuation and line content remain exactly as written. It is a safe, non-destructive way to tidy formatting without any risk of altering meaning.

Can I collapse spaces but keep my line breaks?

Yes. Collapsing multiple spaces works within each line and does not merge separate lines together. Line breaks are preserved unless you specifically enable the remove-blank-lines option, giving you fine control over the final layout of your text.

Does it show me what changed?

The tool displays before-and-after statistics such as the number of characters and lines removed, so you can see the impact of your cleanup at a glance. All processing happens in your browser, keeping your content completely private.
