I made an online file converter that converts anything to anything, and does so privately.

PortalRunner

A developer built a browser-based file converter that works entirely locally, converting between any file formats including cross-medium conversions (like video to PDF or images to audio). The project uses WebAssembly ports of FFmpeg and ImageMagick, custom-built Office document parsers, and clever algorithms like Fourier transforms for audio-to-image conversion. The system uses breadth-first search to chain conversion tools together, routing through intermediate formats to reach any target format. All processing happens client-side for privacy, with lazy-loading to reduce initial bundle size.

I Made the Ultimate File Converter

Yet another garbage tool. Convert JPG to MP3? I’ve tried to convert the easy PDF doc to Markdown. Instead of markdown I’ve got the *.md file with the base64 encoded PNG inside. Very useful! :-/

What is the use of this descriptions? Video to PDF, Image to audio based on this convertor.
The only thing I can think of is:
it uses AI to create a PDF transcript from video.
or
Describe an image in audio

Instead of this I would just like a blistering fast, low cpu, locally available pdf generator that keeps being supported and has support for the advanced features like forms. But instead I have this…

It work with docs to pdf , pdf to image but very poorly.
