Free Online Tools – No Upload Required
Most “free online tools” make you upload your photos, PDFs and documents to their server — and you simply have to trust what happens to them there. Professor Tech tools are different: they run entirely inside your web browser, on your own device. The file you open is read by your browser, processed on your device, and the result is downloaded straight back to you.
What does leave the browser? Only a few things, none of them your files: the tool code itself loads from public library CDNs, and anonymous usage statistics may be measured (which pages are used, no names, no files). Details in our Privacy Policy and Terms & Conditions.

Professor Tech — by Muhammad Uzaif Jakhar
Assalam-o-Alaikum! I am Muhammad Uzaif Jakhar — a graphics designer and computer expert, and the person behind Professor Tech. I built this toolbox from the real work that comes into my shop every day, so students, office staff and shopkeepers can finish their computer tasks quickly, free, and without installing anything.
From logo and panaflex design at Friends Graphics to tech videos on the Professor Tech channel — the goal is the same: make technology simple and useful for everyone.
