About these tools

Count, convert and clean up text, live as you type. They share a small number of engines configured differently on each page — a target file size, and where a form demands it, exact pixel dimensions. The result is tuned to the specification you actually need to meet, rather than a generic "make it smaller" pass.

Processing happens on your device. Your files are never uploaded to a server, which is why there are no usage limits and no account to create.

Frequently asked questions

What text tools are on this site?

There are 14 in this category: Word Counter, Character Counter, Case Converter, Remove Duplicate Lines, Reading Time Calculator, Diff Checker, and 8 more. Count, convert and clean up text, live as you type.

Are the text tools free to use?

Yes. No account, no trial, no watermark and no cap on how many files you process. Every setting is available to everyone.

Do my files get uploaded?

No. These tools run entirely in your browser, so the file never leaves your device. You can confirm it in your browser’s Network tab, or by disconnecting from the internet once the page has loaded — the tools keep working.

Do I need to install anything?

No. There is nothing to download and no extension to install. Open the tool you need and use it.

Is there a limit on how much text I can paste?

Not one we impose. Everything runs in your browser, so the practical limit is your device’s memory. Very large inputs slow down rather than being refused.
