Do this automatically in Chrome — try Unit Converter Pro.
Add to Chrome — FreeAre SmallPrep's tools really free?
Yes — every tool on this page is free to use, with no account or signup required.
Do these tools upload my files to a server?
No. Every tool runs entirely in your browser using JavaScript. Your files never leave your device.
Is there a file size limit?
Since processing happens locally in your browser, the practical limit depends on your device's memory rather than a server-imposed cap.
