How to download WebP and AVIF images
Short answer
WebP and AVIF are ordinary image files, so they can be downloaded like any other. The friction comes from sites serving them through picture elements and CSS backgrounds, where the right-click menu doesn't offer the real file. A bulk downloader reads the actual image URLs and saves the originals.
Doing it by hand
Right-click and Save image as… works when the image is a plain img tag pointing at a .webp or .avif file.
When it isn't, the usual fallback is DevTools: open the Network tab, filter to Img, reload, and pick the request out of the list.
Where that falls apart
- Sites often deliver several sources per image and the menu hands you whichever one the browser happened to pick — usually not the largest.
- CSS background images have no context menu entry at all.
- Some browsers offer to convert the file on save, which re-encodes it and loses quality.
- Doing any of this for a whole gallery is not a realistic use of an afternoon.
Doing it with ImgDown
Step 1
Open the image list on the page
Click the toolbar icon and scan the current tab. The extension collects the real image URLs, including the ones the context menu skips.
Step 2
Filter to the formats you want
Tick WebP and AVIF in the file-type filter to see only those, or leave everything on to grab the page's JPGs and PNGs in the same pass.
Step 3
Download the originals
Files are saved byte-for-byte as the site serves them — no re-encoding, no quality loss, extensions intact.
