Paper & Text Tools
Two small, free tools for two everyday annoyances. Each one does one job, explains how it works, and runs entirely in your browser.
Paper weight converter
Turn "80 lb cover" or "24 lb bond" into gsm (g/m²), compare grades, and estimate what a stack of sheets weighs. The US "lb" number depends on the paper grade, and this tool does the conversion for every grade at once.
Text cleaner
Paste text from a PDF, Word file or web page and get plain text back: straight quotes, no stray line breaks or invisible characters, duplicate lines removed, and case changed if you want.
Why these tools are different
- Private by design. All the work happens on your device. There are no forms, accounts, cookies or analytics scripts. See the privacy page.
- Explained, not just calculated. Each tool page shows the method, worked examples you can check by hand, the edge cases where answers go wrong, and dated sources.
- Fast on a phone. No frameworks and no third-party scripts.
