Why TextTrimmer
Most "free" text tools quietly send whatever you paste to a server. TextTrimmer doesn't — every tool on this site is plain JavaScript running in your own browser tab. Close the tab and the text is gone. Nothing is logged, stored or transmitted.
That also makes the tools fast: there's no upload, no processing queue, no waiting. Counts and conversions update as you type.
Who these tools are for
- Writers & editors checking word counts or hunting duplicate lines in a manuscript.
- Students meeting an essay's word-count requirement before submission.
- Developers generating placeholder copy or one-off passwords.
- Marketers cleaning up text pasted from PDFs or emails before publishing.

Can I use these tools on mobile?
Yes, every tool is built to work on phones and tablets as well as desktop browsers.
