A small, polished Windows utility built around yt-dlp and FFmpeg: paste a link, pick video and/or audio with a format and quality, and download — plus a separate local-file converter tab for re-encoding format, quality, and bitrate. Bilingual UI (Ukrainian/English), light/dark theme, and a one-file installer with the engine bundled in, so the very first click doesn't wait on a ~100MB tool download.

Approach
- yt-dlp + FFmpeg engine, auto-fetched on first run or bundled into the installer at build time
- Video and audio downloads as independent toggles, each with its own format/quality
- Standalone converter tab: pick a local file, re-encode to a different container, quality, or bitrate
- Automatic retry on transient YouTube download errors
- Bilingual UI with a live light/dark theme switch
- Packaged as a single-file Windows installer via PyInstaller
Verification note
A personal utility tool, built and manually tested end to end (real downloads, real conversions, both themes, both languages). Not published to a store or measured for install/user counts.
