✓Paste straight from Word, Google Docs, PDFs, or web pages — formatting is stripped automatically.
✓Chain text tools together: clean whitespace, then change case, then count words.
✓Everything runs locally in your browser — your input is never uploaded to a server, so it is safe for private or sensitive data.
✓Large documents still process instantly because the work happens on your device, not a server.
✓Bookmark the tool for one-click access whenever you need it.
