About techfen

techfen is a collection of free online tools built for everyday tasks in India: getting a photo ready for an exam form, compressing a PDF for a government portal, working out an EMI or income tax, or generating a rent receipt.

Why we built it

Most people fill online forms on their phone. Upload limits like "photo under 20 KB" or "signature 140 × 60 pixels" are confusing, and many tools that promise to help are slow, full of pop-ups, or ask you to upload personal documents to an unknown server. We wanted something faster and more private.

How our tools work

Every image and PDF tool on techfen runs entirely in your web browser. Your files are never uploaded to our servers. When you close the tab, they are gone.

Accuracy

Our calculators use formulas and rates that we review regularly, but rules such as tax slabs and exam requirements change. Always confirm important numbers with the official source. See our disclaimer for details.
