About
Hi, I'm Yogendra Singh, and TeraConvert is a small project I build on my own. No company behind it, no investors, no marketing team, no ad budget. I got tired of uploading private files to random websites just to change a file format, so I started putting together the converter I wished already existed.

Most online converters work the same way: you hand over your file, it gets uploaded to a server you know nothing about, something happens, and you download the result. For a holiday photo that might be fine. For a signed contract, a passport scan, an unreleased design, or a medical PDF, it is not. You have no idea where the file went, who can read it, or how long it sits there.
I wanted the opposite of that. Drop a file in, get the converted file back, and have the whole thing happen on your own machine so the file never travels anywhere. The browser already ships with everything needed for a lot of this work: Canvas, WebCodecs, WebAssembly. The desktop already has battle-tested tools like FFmpeg and ImageMagick. Nobody had stitched them into something that just worked and stayed local. So I did, on nights and weekends, one format at a time.
TeraConvert comes in two pieces. The web app is free and runs entirely in your browser tab. The desktop app is a one-time purchase that uses native engines for the heavy formats a browser cannot touch. Both follow the same rule: your files stay with you.
What I stand for
Every conversion runs on your own machine. The web app does it in your browser tab; the desktop app does it with native tools on your disk. Nothing is uploaded, queued on a server, or sat in someone else's bucket. There is no file to leak because the file never leaves.
The desktop app is a single one-time payment, not a subscription. No seat counting, no monthly renewal, no feature held hostage behind a higher tier. The web app is free and stays free. I would rather sell a tool than rent you access to one.
Behind the simple drop zone are the real engines people trust: FFmpeg, ImageMagick, Ghostscript, Pandoc, LibreOffice, Tesseract, and the macOS native tools. No half-working stub paths. If a format pair is offered, there is a real engine doing the work.
A browser cannot do everything a desktop can, and TeraConvert says so plainly instead of failing quietly. When the browser hits a wall, the page tells you and points to the desktop app. No fake progress bars, no silent corruption, no pretending.
TeraConvert is operated by me, Yogendra Singh, as a sole proprietor in Pune, Maharashtra, India. I write the code, design the pages, answer the email, and ship the releases. When something breaks, it is one person fixing it, and that person is reachable.

yogendrasingh.inI have shipped web apps, native desktop and mobile software, and a fair amount of low-level glue between them. TeraConvert is where I put that experience toward a problem I have myself every week. The portfolio has the rest of the work.
No support call centre, no offshore desk, no chatbot. One inbox, read by me. Refunds inside the window need no justification. The legal pages name a real person, not a shell.
Contact & supportI read every message. Questions, feedback, bug reports, or a format you wish TeraConvert supported, send them over. If you are weighing the desktop app, the pricing page lays out exactly what you get for the one-time price.
