简介

Media Extractor Pro finds the video, audio and images on the page you are viewing and lets you preview and download them, including streaming video that a plain "Save as" can't get.

STREAMING VIDEO SAVED AS A REAL MP4
Most sites don't serve one video file. They stream hundreds of small segments through HLS or DASH. Media Extractor Pro downloads every segment and joins them into one standard MP4 that plays anywhere: VLC, QuickTime, your phone, a video editor.
• HLS (.m3u8): master and variant playlists, AES-128 encrypted segments, byte-range and fragmented-MP4 playlists, subtitle tracks
• DASH (.mpd) manifests
• Separate audio and video tracks are merged into a single file whenever the format allows it
• Failed segments are retried automatically, and every download can be cancelled

WORKS WITH MODERN PLAYERS (MSE CAPTURE)
Some players never expose a usable URL: the video shows up as "blob:". For these, Media Extractor Pro records the data the player itself feeds to the video while it plays, whatever format or URL scheme the site uses. Play the video through to the end, then save it as one MP4 with video and audio merged. Long videos are buffered on disk, not in memory.

DETECTS EVERYTHING ON THE PAGE
• Media found in the page itself: video and audio tags, links, embedded player data, structured metadata, and the preview video and image shown when the page is shared
• Media found in network traffic, so files loaded by scripts are caught too
• Works across all frames, including embedded players
• Images: the full-size version is listed instead of the thumbnail (galleries, lightboxes, srcset, and the common thumbnail URL patterns of Twitter, Wikimedia, Reddit, Imgur and WordPress), plus CSS backgrounds and large images loaded on click
• Duplicates are removed automatically, and the renditions of the same video are grouped by quality

FAST, ORGANISED DOWNLOADS
• One-click Download, Download Selected, Download All, or Best (highest quality of each item)
• Batch downloads are bundled into one ZIP file, so you choose a location only once. There is a progress bar and a cancel button, and archives over 4 GB are supported
• Download queue with a configurable number of parallel downloads, retry and cancellation
• Batch rename with patterns (page title, original name, domain, date)
• Sort and filter by type (video, audio, image, stream), quality, size, name or domain
• Copy all URLs to the clipboard, or export the list as .txt or .json

PLAYLIST MODE
On demand only: scan the same-site links of a page (up to 40). They are opened a few at a time in muted background tabs, and the videos found on each page are collected into your list, labelled with that page's title.

SETTINGS
• Filename pattern and download subfolder
• Minimum and maximum file size, and minimum image size
• Advertising filter with your own blocked domains and patterns
• Watch mode
• Dark and light theme

PRIVACY
• No data collection, no analytics, no remote code. Everything runs locally in your browser
• Private windows stay private: captured video is never written to disk, downloads stay in the private session, and requests are sent without your normal-session cookies

LIMITATIONS
• DRM-protected content (Netflix, Disney+, Prime Video and other Widevine or PlayReady streams) is not supported and never will be
• MSE capture only records what has been played, so play the video to the end

PERMISSIONS EXPLAINED
• Access to all websites: needed to detect media on any page you visit and to download stream segments
• Downloads: to save files to your computer
• Web requests: to detect media files in network traffic and to send the headers some sites require for segment downloads
• Tabs and active tab: to show the media of the current tab and to run playlist mode
• Storage: to keep your settings and the detected media list
• Clipboard: for "Copy all URLs"

Please only download content you have the right to download, and respect the terms of the websites you visit.
