Split the file.
Split the file.
Not your patience.
PDownloader tears large downloads into parallel byte-range segments, resumes what breaks mid-transfer, and pulls YouTube and HLS streams into one clean queue.
What it does
One engine, every kind of download
The same engine handles plain files, broken connections, and streaming media.
Resume & retry
Segment progress persists to disk between runs.
HLS / DASH streaming
Detects .m3u8 playlists and merges fragments.
YouTube via yt-dlp
Resolves formats and streams; PDownloader handles the transfer.
Browser extension
Context-menu capture and a manual URL popup.
Tray & background service
Coordinates the UI, download window, and tray icon over IPC.
Under the hood
Four small processes, one local bridge
The browser extension talks to a local HTTP bridge; everything else is routed over CFS.
