Every semester I found myself bouncing between five different websites just to calculate my CGPA, check attendance percentage, split a grocery bill with roommates, or merge a couple of PDFs for a submission. Eventually I got annoyed enough to just build all of it myself, in one place.
What it does
Toolbench is a collection of 38 free tools organized into categories:
- Academic — CGPA/GPA calculators, required marks calculator
- Attendance — percentage tracker, "classes needed" and "classes I can miss" calculators
- Student finance — expense splitter, EMI/interest calculators
- PDF tools — merge, split, image-to-PDF
- Image tools — compress, resize, format conversion
- Developer tools — JSON formatter, Base64 encoder/decoder, UUID generator
- Everyday — age calculator, tip calculator, GST/discount calculators, BMI
- Study & focus — Pomodoro timer, exam countdown
How it's built
Everything runs entirely client-side in the browser — no backend, no file uploads, no accounts. PDF handling uses pdf-lib, QR generation uses qrcodejs, everything else is vanilla JS. It's hosted free on Netlify.
There's also a small blog section with 19 explainer guides behind the calculators (how CGPA math actually works, why 75% attendance rules exist, simple vs compound interest, etc.) — mostly so the site has real written content, not just bare tools.

Would love feedback — especially on what tools are missing, or things that could work better. Happy to keep adding to it.
