About
Free tools that respect your time and your data.
OneClickUse is a small, fast collection of utilities for everyday PDF, image, text, calculator, and converter tasks. No signup. No watermark. No catch.
Why this site exists
Most online tool sites are slow, ad-stuffed, or quietly upload your files to their servers. We wanted the opposite: open a page, drop a file or type some text, get a result, leave. That's it.
Most tools here use well-established open-source libraries (pdf-lib, pdf.js, jspdf, browser-image-compression, jszip, and a few others). Many everyday workflows happen on your CPU, while advanced PDF workflows use a configured backend service.
What we don't do
- We don't require accounts or store files for normal tool use.
- We don't have user accounts. Nothing to log in to.
- We don't track you across the web. See our Privacy page.
- We don't email you. We don't have your email.
What we will do
- Ship 3–5 new tools per week. See the Changelog.
- Show some ads to keep the lights on. They're never injected into your output files.
- Listen — if a tool is missing or broken, tell us.
