Convertio.Pro

A backend-powered file conversion platform

A browser-based file conversion platform combining React and Vite with PHP, Python processing workflows and FFmpeg for handling multimedia transformations.

01

The challenge

File conversion involves resource-intensive operations that can block application requests, consume server resources, and create unnecessary exposure of uploaded files.

02

The approach

I built the frontend with React and Vite, connected it to a PHP and Python backend, and integrated FFmpeg for media processing. Background processing and temporary cloud storage separate conversion workloads from the user interface.

03

The outcome

A conversion workflow designed to handle resource-intensive media operations independently while keeping the interface responsive and uploaded files temporary.
