Free online tools, built to be genuinely useful

WestNet Learning publishes clinical-education modules and practical guides — and this is our free toolbox. Every tool loads fast, works on your phone, and runs in your browser, so the text you paste, the images you upload and the codes you scan stay on your device. There is nothing to install and nothing to sign up for.

Popular picks

These tools sit alongside our continuing-education courses, free Word & PDF editors, the WestNet UPC registry and the parcel tracker.

Frequently asked questions

Are these tools really free?
Yes. Every tool here is completely free, with no account, no sign-up and no watermark. They are provided by WestNet Learning alongside our courses and guides.
Do you upload or store what I paste or scan?
No. The tools run in your browser, so the text you type, the images you upload and the codes you scan stay on your device. The QR scanner keeps its history in your own browser, not on our servers.
Do they work on my phone?
Yes. Every tool is mobile-first and works on phones, tablets and desktops. The QR scanner can use your phone’s camera directly.
Can I use these tools for schoolwork or at the hospital?
Absolutely. Students, teachers, nurses and clinicians use these daily — from the BMI and unit converters to the word counter and scientific calculator. They are free for personal, academic and professional use.
