About this extension
Media Grabber finds every video, audio track and image on a page and
saves it in the quality you choose.
No digging through developer tools,
no pasting links into a website you do not trust. Everything runs on your
own machine.


Most download add-ons only handle a plain video file, and modern sites
almost never serve those. Media Grabber understands how video is really
delivered:
  • Adaptive streams (HLS and MPEG-DASH) — the kind split into thousands
    of small pieces. Every segment is fetched and rebuilt into one file.
  • Split audio and video — many sites store them apart. Both are
    downloaded at once and joined back together with no re-encoding, so
    there is no quality loss and no long wait.
  • AES-128 encrypted segments — handled automatically.
  • Direct files — MP4, WebM, MKV, MOV, MP3, M4A, OGG, WAV and more.
  • Subtitles and images, including whole galleries.


Every resolution the site offers, listed with its real bitrate and
estimated file size, right up to 4K where it exists. Take the best copy or
a small one. Want only the soundtrack? Pull the audio track on its own.


Select a whole page of media and save it in one go — images and clips
together. Filter by type or minimum size first, so you get full-resolution
pictures instead of thumbnails.


Finish as the file you actually needed: MP4, MKV, MP3, WAV or GIF.
Conversion runs locally in your browser through WebAssembly. Nothing is
uploaded to a server and there is no queue.


Built by Ryonix Labs, a security practice. That shapes how it works:
  • No browsing history is collected. What you detect and download stays on
    your machine.
  • No account is needed to download. Sign-in exists only to manage a
    licence.
  • Stream reassembly and conversion happen in your browser, never on a
    server.
  • No third-party analytics or trackers.

The add-on contacts exactly one server, and only when you activate a
purchased licence.


3 downloads a day and 10 a month, plus 50 bulk items a month.


$9.99 once, yours for good, all future updates included. One licence
activates two browsers — your laptop and your desktop, or Firefox and
Chrome, from a single purchase. You can see your activations any time and
release one to move it elsewhere.


Media Grabber does not break copy protection. DRM-protected streams
(Widevine, PlayReady, FairPlay) are detected and refused rather than
half-downloaded, so you never end up with a broken file and no
explanation.

Please respect copyright and the terms of service of the sites you use.
