Free Plain Text Formatter that works offline
The plain text formatter cleans copied content without changing it into a proprietary document format. It can trim each line, collapse repeated spaces, limit blank lines, normalize Windows and Unix line endings, and replace tabs with a chosen number of spaces.
What this plain text formatter does
Text copied from PDFs, spreadsheets, terminals and content management systems often contains invisible formatting problems. Extra spaces make diffs noisy, mixed line endings confuse command-line tools, and long runs of blank lines create awkward layouts. The checkboxes let you apply only the cleanup rules your content needs.
How to use the Plain Text Formatter
- Paste unformatted text into the input editor.
- Enable or disable each whitespace cleanup rule.
- Choose a tab width if tabs should become spaces.
- Select Format text, inspect the clean result and copy it.
Common uses
- Cleaning text copied from PDF documents or email
- Preparing consistent plain text for a CMS or support system
- Normalizing configuration and source snippets before comparison
- Removing accidental whitespace from AI-generated or transcribed content
Private processing and offline access
This tool does not submit your input to a conversion server. Processing takes place inside the browser using local JavaScript and standard Web APIs. After the PWA has been installed or cached, the page and its core features remain available without an internet connection. Closing or clearing the page removes unsaved input; the tool does not create an account or cloud history.
Tips for accurate results
- Keep tab conversion disabled for formats where tab characters carry meaning.
- Review poetry and fixed-width text carefully because deliberate spacing can be significant.
- The formatter reports how many unnecessary characters were removed from the source.
Frequently asked questions
Does the formatter change words or punctuation?
No. It applies the selected whitespace and line-ending rules; it does not rewrite the wording.
Can I keep multiple spaces?
Yes. Disable Collapse repeated spaces and the formatter will leave spaces inside each line unchanged.
What line ending does normalization use?
Normalized output uses the standard LF newline character, which works well across modern systems.
