DexSavesImages by DexMakesExtentions

DexSavesImages automatically saves images as they load on the sites you choose — no more right-click-save one at a time.

Per-site control:
Auto-save is off everywhere by default. Turn it on for a site from the toolbar popup and it only runs there — every other site stays off until you enable it too.

What it captures:
Regular images, lazy-loaded and dynamically swapped images, responsive srcset images, and CSS background-images — including images that load in while you're actively scrolling through a long feed.

Smart filenames on Reddit:
On Reddit, saved images are automatically named after the post they came from instead of a random CDN filename.

No duplicates:
DexSavesImages remembers what it's already saved, so reloading a page or revisiting a post won't save the same image twice. Reset the history any time from the popup.

Stay in control.

Privacy first:
Everything happens locally in your browser. DexSavesImages has no server, sends no data anywhere, and uses no analytics or tracking of any kind.
