Text Cleaner

The text cleaner runs a selectable set of cleanup operations on your input in one pass. You can collapse extra spaces, remove line breaks, strip HTML tags, fix smart quotes and em-dashes, remove emoji, drop URLs and email addresses, normalize unicode, and 9 other operations. Each operation is a checkbox you turn on or off, so you control exactly what gets touched.

Use a preset when your text matches a common source: AI-pasted text from ChatGPT or Claude, a Word document copy, a PDF copy-paste, a code comment block, or a blog post draft. Each preset turns on the operations that source typically needs and leaves everything else off. You can always tick or untick individual operations after applying a preset.

A remove line breaks tool does one job: strip newline characters. The text cleaner is an umbrella tool that bundles 16 cleanup operations including remove line breaks, plus removing HTML, fixing quotes, dropping emoji, and 12 others. If you only need to remove line breaks, use the dedicated tool. If your text has several problems at once (typical for AI-generated or copy-pasted content), use this cleaner.

No. The input box is what you paste in. The output box shows the cleaned result. Your original text on disk or in another app is never touched. Everything runs in the browser, and the input is held in memory only while the tab is open.

Operations run in a fixed order regardless of how you check them: remove HTML tags first, then drop URLs and emails, then remove emoji and non-ASCII, then convert smart quotes and em-dashes, then normalize unicode, then drop tabs, then remove line breaks, then collapse multiple spaces, then trim whitespace, then remove empty lines, then optional lowercase. This ordering prevents one operation from breaking another (for example, you do not want to lowercase before stripping HTML because tag names get lowercased pointlessly).

Smart quote conversion is a fix: it replaces curly quotes and em-dashes with plain ASCII equivalents while keeping the punctuation in place. Remove punctuation is a delete: it strips all ASCII punctuation marks completely. Most cleanup workflows want the first (fix encoding) without the second (delete content), so they are two separate checkboxes.

Some characters can be written two different ways. The letter é can be one code point (U+00E9) or two (U+0065 plus a combining accent U+0301). The NFC normalization rewrites both forms to the single-code-point version. This matters for search, deduplication, and database keys. Most text editors store NFC by default, but text pulled from clipboard pipelines (especially Mac to Windows) often arrives in the decomposed form.

No. Every cleanup operation runs in your browser in sequence. The original document, the intermediate states between steps, and the final cleaned output all live in this tab. Nothing is sent to a server at any stage.
