Features

One app, four jobs.

Arclio isn’t just a downloader. It’s where the files end up living, too.

Download engine

The most capable downloader on the internet, made usable.

Arclio wraps yt-dlp and FFmpeg — the same engines power users run from a terminal — behind a wizard that a first-time visitor can finish without reading anything.

  • Paste a single link, a playlist, a channel, or a mixed list at once
  • Built-in profiles: Best available, 4K UHD, QHD, 1080p, 720p, Smart-TV MP4, audio-only
  • Interactive mode exposes every resolution, codec, and audio track yt-dlp reports
  • SponsorBlock segment skipping, subtitle download (embedded or sidecar, per-language)
  • Resumable queue — pause, close the app, and pick up where you left off
Arclio's download screen
Library

A home for what you've collected, not just a downloads folder.

Every pull gets indexed automatically — metadata, thumbnail, and all — into a local library you can actually search and organize.

  • Five media kinds recognized: video, audio, documents, comics, and images
  • Collections and tags for grouping across sources
  • Favorites and playback/reading history
  • Full-text search across titles, authors, and descriptions
Filter: video · comic
12 collections
340 items indexed
Converter

Change the format after the fact, without leaving the app.

A built-in, FFmpeg-powered converter for the changes people make after downloading — extract audio from a video, shrink a file, or turn a clip into a GIF.

  • Video transcoding between MP4, MKV, WebM, and AVI
  • Audio extraction and conversion — MP3, AAC, FLAC, Opus, WAV
  • Resize, trim, and re-encode without a second tool
  • GIF creation from any video clip
input.mkv → output.mp4
Extract audio → FLAC
00:12–00:48 → clip.gif
Viewer

Open what you saved, right where you saved it.

PDFs, comic archives, and images open in dedicated viewers built into Arclio — no juggling a separate reader for every file type.

  • PDF viewer with zoom and page navigation
  • CBZ / comic-archive reader with page pre-fetching for fast paging
  • Image viewer for everything else in the library

Zoom 140%
Archive: 212 pages

21 languages, real RTL support

Including Arabic, Urdu, and Pashto — with layout, wizard steps, and queue animations that mirror correctly, not just translated strings.

Bulk, without the mess

Paste dozens of URLs at once — duplicates get cleaned, non-media links get filtered, and you review before anything queues.

Local-first, always

Everything runs on your machine. The queue survives a restart, and nothing phones home unless you explicitly turn analytics on.

Ready when you paste the first link.

Pick your platform below — it takes about a minute to install.
