Media Grabber — by Panielix LLC

About

Media Grabber surfaces every downloadable image and video on the page you're
  looking at — sorted highest quality first, with file size probed in the
  background — so you can grab the version you actually want with one click.

  ────────────────────────────────────────
  HOW IT WORKS
  ────────────────────────────────────────

  1. Hover any image or video — a small ⬇ button appears at the top-right
     corner.
  2. Click it — see every variant Media Grabber could find, ordered highest
     quality first, with dimensions, format, and file size.
  3. Click a row — the file saves to your Downloads folder. Done.

  You can also right-click any image or video and pick "Download image" or
  "Download video" without opening the picker.

  ────────────────────────────────────────
  WHAT IT FINDS
  ────────────────────────────────────────

  • <img> elements — including srcset, currentSrc, and common lazy-load
    attributes.
  • <picture> elements with multiple <source> candidates.
  • <video> and nested <source> elements.
  • CSS background-image declarations on any element.
  • Elements inside open Shadow DOM roots.
  • Higher-resolution variants that aren't in the DOM, via built-in CDN
    upgraders for Unsplash, Cloudinary, Imgur, Wikipedia thumbnails,
    Twitter/X, Reddit, Discord, and Pinterest — plus a generic ?w= / ?width=
    upgrader.
  • blob: URL images on same-origin / CORS-allowed pages, recovered via a
    canvas re-render.

  ────────────────────────────────────────
  THINGS YOU CAN CUSTOMIZE
  ────────────────────────────────────────

  • FILENAME TEMPLATES. Use {filename}, {host}, {date}, {timestamp}, {alt},
    and {title}. Put forward slashes in the template to organize into
    subfolders. Set per-domain overrides.
  • CUSTOM CDN TRANSFORMS. Add your own regex → replacement rules in
    Advanced settings to cover any CDN the built-ins don't.
  • THEMES. Dark, Light, Midnight, Sepia, or Auto (follows your OS's
    prefers-color-scheme).
  • QUICK DOWNLOAD. Skip Chrome's Save As dialog by default — files go
    straight to your Downloads folder.
  • HOVER OVERLAY. Toggle the ⬇ button off if you'd rather only use the
    toolbar popup and right-click menu.
  • RECENT DOWNLOADS PANEL. Last 10 extension-initiated downloads with
    Open, Show in folder, and Re-download buttons.

  ────────────────────────────────────────
  PRIVACY (TL;DR — there is none to worry about)
  ────────────────────────────────────────

  • NO TELEMETRY. NO ANALYTICS. NO REMOTE LOGGING. Media Grabber does not
    run a server; we receive no events of any kind from your browser.
  • NO USER ACCOUNTS. You don't sign in. We cannot identify you.
  • The only outbound network requests the extension makes are:
      – HEAD probes directly to the media URL to read file size and content
        type. These go with credentials: "omit", so your cookies are NOT
        sent to third-party CDNs.
      – The download itself, via Chrome's native chrome.downloads API, which
        fetches the file directly from the media URL.
    Neither of these passes through any Panielix server.
  • Settings live in chrome.storage.sync — your Chrome profile, not our
    servers.

  ────────────────────────────────────────
  WHAT IT IS NOT
  ────────────────────────────────────────

  To set expectations honestly:

  • It is NOT a YouTube / Instagram / TikTok downloader. Streaming services
    that deliver video via HLS or DASH manifests are out of scope —
    Media Grabber scans what's in the DOM and applies generic CDN
    transforms; it does not reconstruct adaptive streams.
  • It does NOT bypass DRM, paywalls, or login walls. If a page has not
    rendered the media to you in the browser, Media Grabber cannot see it.
  • It does NOT scrape cross-origin iframes or closed Shadow DOM.
  • HEAD size probes are best-effort — some servers omit Content-Length, in
    which case the size column shows a dash.

  ────────────────────────────────────────
  SUPPORTED BROWSERS
  ────────────────────────────────────────

  Any Chromium-based browser supporting Manifest V3:

  A Firefox port is not currently planned.

  ────────────────────────────────────────
  PERMISSIONS — WHY EACH ONE
  ────────────────────────────────────────

  • activeTab — to read the DOM of the tab you are currently on so we can
    find images, videos, and CSS backgrounds.
  • downloads — to save the file you pick. Without this we cannot write to
    your Downloads folder.
  • storage — to persist your settings and the Recent downloads list.
  • contextMenus — to add the "Download image" / "Download video" entries
    to the right-click menu.
  • scripting — to inject the hover overlay and variant picker into pages on
    demand.
  • Host permission <all_urls> — to run on whatever site you are on. The
    extension only READS page content; it never modifies the page or its
    data.

  Per-permission justifications (review-form fields)

  activeTab — Required to read the DOM of the active tab on demand
  (after a user gesture such as opening the popup or right-clicking)
  so the extension can enumerate images, videos, <picture>, <source>,
  and CSS background-image declarations on that page. Not used to
  modify the page.

  scripting — Required to inject the hover-overlay and variant-picker
  UI into the active tab when the user invokes the extension. Inject
  on demand only; not registered as a persistent content script.

  downloads — Required to write the user-selected media file to the
  browser's Downloads folder via chrome.downloads.download(). This is
  the core function of the extension.

  storage — Required to persist user preferences (theme, filename
  template, per-domain overrides, custom regex transforms, UI toggles)
  and the bounded Recent downloads list (last 10 entries). Stored in
  chrome.storage.sync so the settings follow the user's Chrome profile.

  contextMenus — Required to add "Download image" and "Download video"
  entries to the right-click menu when the user right-clicks on an
  image or video element.

  Host permission <all_urls> — Required because the user may want to
  download media from any web page they visit. The extension only
  reads page content (queries the DOM, reads element attributes); it
  never modifies the page, injects ads, or sends page content to any
  remote server.
