Web Resource Saver

Web Resource Saver – save any webpage (with all static assets) as an offline ZIP in one click. Double-click the local index.html to reopen the page without an internet connection.
Built for Chromium-based browsers (Chrome / Edge), Manifest V3, no background scripts, zero data collection.
Key Features
Auto-sniffing – uses the Performance API to capture every resource loaded by the page: HTML, CSS, JS, images, fonts, audio, video, XHR/Fetch, etc.
Smart completion – automatically sends HEAD requests for zero-byte files and fills in the real size.
Group & Filter – assets are sorted into img / css / js / font / video / audio / other; real-time keyword filtering included.
Truly offline – optionally embed the main HTML and rewrite all paths to relative URLs; after extracting the ZIP, simply open index.html to get a fully-working mirror (perfect for games, docs, tutorials).
Batch operations – select all / invert / copy links / download as ZIP with a live progress bar.
Advanced options – keep query strings, skip 403/404, dark mode, multilingual UI (EN / ZH) switchable in one click.
Settings sync – export / import configuration as JSON; restore everything on a new machine in seconds.
Permission Usage
read the current tab’s resource list only.
scripting – inject Performance-query code.
storage – save user settings & language preference.
No personal data is collected or uploaded.
FAQ
Q: Can it save dynamically-rendered pages?
A: It grabs the final DOM snapshot plus all resources that have already loaded; data fetched later by JS must be saved manually in a second pass.
Q: Why do some resources fail to download?
A: Cross-origin restrictions or servers that block HEAD may return 403; toggle “Skip errors” in settings to ignore them automatically.
Q: Firefox support?
A: Not planned.
