✓Paste directly from any source — Word documents, PDFs, websites, or emails.
✓All processing happens in your browser — your text is never sent to any server.
✓Use multiple text tools in sequence to chain transformations (e.g. clean whitespace → convert case → count words).
✓For large documents, processing is still instant as the tool runs entirely client-side.
✓Bookmark this tool for quick access whenever you need to manipulate text without opening an app.
