I'm Rehan Baqir, a UI/UX designer and developer based in Islamabad, Pakistan. I started Vertex Solutions to solve a simple frustration: everyday tools — merging a PDF, resizing an image, checking a loan calculation — shouldn't require an account, an install, or uploading your files to someone else's server.
Every tool on this site runs in your browser, and most never send your files anywhere. I write the guides myself, and each one is tested against the actual tool before it goes live. When a browser-based workflow has limits — and they always do — I say so plainly instead of pretending otherwise.
What I cover
- PDF workflows — merging, splitting, compressing, and converting PDFs without desktop software.
- Everyday calculators — finance, math, and health calculators with the formulas explained, not just the answers.
- Image tools — resizing, converting, and compressing images for the web.
- Developer utilities — JSON, Base64, regex, and encoding helpers.
- Browser privacy — what actually happens to your files and data when you use online tools, and how to stay safe.
How I work
- I build or test the tool first, in a real browser.
- I write the guide from what actually happened — including edge cases and error messages.
- I re-test after site updates. Guides that go stale get corrected, and the correction is reflected in the article's updated date.
