Desktop Engine

The Desktop App Does the Heavy Lifting

Browsers can detect media, but they cannot download HLS/DASH streams, merge video and audio, or convert formats. Those jobs all run in the desktop app — locally, at native speed.

Why Desktop

Why the Desktop App Is Required

The browser extension sniffs media resources and shows the UI. The actual downloading, stream merging, format conversion, and file management all happen in the desktop app — browsers simply cannot do this.

Extension Only

Limited
  • Detect media resources on web pages
  • Show the download popup and pick quality
  • Cannot download HLS / DASH streams (m3u8, mpd)
  • No format conversion or audio extraction
  • No resume for broken downloads
  • Capped by browser file-size and speed limits

Extension + Desktop

Full Power
  • Everything the extension does
  • Download HLS / DASH streams and merge segments
  • Merge video + audio, extract MP3 (built-in ffmpeg)
  • Resume broken downloads, queue batch tasks
  • Native Rust + tokio engine — no browser limits
  • Runs locally — no media leaves your machine

Native Download Engine

Built on Rust + tokio, the desktop app bypasses browser download limits for maximum speed and stability on large files and live streams.

HLS / DASH Stream Merging

Downloads m3u8 and mpd playlists, fetches every segment, and merges them into a single MP4 — something a browser cannot do.

Conversion & Audio Extraction

Ships with ffmpeg: video to MP4, video to MP3, audio extraction, and remuxing — no extra software needed.

Resume & Batch Processing

Resume broken downloads, queue multiple tasks, and run them in the background while you keep browsing.

All processing is local. The extension and desktop app talk over Chrome Native Messaging — no media passes through any server.

Architecture

How the Two Pieces Talk

The extension sniffs media. The desktop downloads and converts. They connect automatically via Chrome Native Messaging — a local, secure channel that needs no server.

01

Browser Extension

Sniffs videos, images, and audio on the page and shows the download UI.

02

Native Messaging

Local, secure channel between the extension and the desktop app.

03

Desktop Engine

Rust + tokio downloads streams; ffmpeg merges and converts them.

Your Files

Saved to your download folder, organized and ready to use.

Download the Desktop App

The desktop app is the real download engine — it downloads, merges, and converts media. The browser extension only sniffs resources on the page.

Download FAQ

Common questions about installation and usage

The browser extension sniffs media resources (images, videos, audio) on web pages and provides the user interface. The desktop app is a background application that handles actual file downloading, format conversion (via built-in ffmpeg), and file management. They communicate automatically via Chrome Native Messaging protocol.
