Frequently Asked Questions
Why does Windows show a SmartScreen warning?
Windows SmartScreen warns about unsigned software. Code-signing certificates cost ~$200/year, which isn't feasible for a free, solo-developed project. The app is 100% open-source under the GPLv3 license - you can inspect every line of code on GitHub.
To run: click "More info" → "Run anyway."
What media sources are supported?
The app uses yt-dlp to support 1,800+ sites including most major video platforms, social media, and public audio hosts. Sites with DRM (Netflix, Disney+, Spotify) are not supported. Some sites (like HiAnime.to) require you to provide browser cookies - see Settings in the app.
What output formats are available?
You can convert to a wide variety of formats grouped by category:
- Documents: PDF, EPUB, DOCX, HTML, TXT, CSV, JSON, XML, YAML, MD
- Images: PNG, JPG, BMP, GIF, TIFF, WebP, ICO
- Archives: ZIP, TAR.GZ, CBZ
- Media: MP3, WAV, AAC, FLAC, OGG, MP4, MKV, WEBM
Is my data private?
Yes, completely. All file processing happens locally on your machine. The app makes no network requests except to fetch media from the source URL. No analytics, no tracking, no cloud processing. Your files stay yours.
Is this really free and open-source?
Yes. The full source code is available on GitHub under the GPLv3 license. You can audit, fork, and modify it freely. There are no ads, no premium tiers, and no hidden costs.
