About FileFlyr

Privacy-first file conversion, powered by modern web technology

Our Mission

FileFlyr was created with one simple goal: make file conversion accessible, private, and free for everyone.

We believe that converting files shouldn't require uploading your personal data to unknown servers, paying subscription fees, or dealing with invasive ads and tracking. That's why we built FileFlyr to run entirely in your browser using modern web technologies.

How FileFlyr Works

Unlike traditional online converters, FileFlyr uses client-side processing. This means:

  • Your files never leave your device - All conversions happen locally in your browser
  • No server uploads - We never see, store, or access your files
  • Instant processing - No waiting for uploads or downloads from servers
  • Complete privacy - No tracking, no analytics on your files, no data collection

We leverage powerful web technologies like HTML5 Canvas API, Web Audio API, and modern JavaScript libraries to provide professional-grade file conversion without compromising your privacy.

The Technology Behind FileFlyr

FileFlyr is built on cutting-edge web standards:

  • HTML5 Canvas - For image processing and manipulation
  • Web Audio API - For audio conversion and processing
  • Open Source Libraries - Including jsPDF, pdf-lib, and more (see licenses)
  • Modern JavaScript - For fast, efficient processing
  • No Backend - Pure client-side application

What Makes FileFlyr Different
