Short answer

Images save as WebP because the website sent WebP. Sites use it because the files are small and load fast, and your browser saves the file it got. To get JPGs on Android, open Stripix, tap Convert, pick the WebP images and tap Convert. The JPGs land in the Stripix album. The Convert tool shows every format it takes.

Why images save as WebP

Many websites send WebP to browsers that can show it, Chrome among them, because a WebP loads faster than the same picture as JPG. Saving an image keeps the file as it arrived, so you get a .webp. Some apps and many upload forms take only JPG or PNG, and that’s where a WebP gets stuck.

Get JPGs with Stripix

Step 1: Pick the WebP images

Open Stripix and tap Convert. In the photo picker, images you saved from a browser are under Albums, in Downloads. Select them and tap Add.

Step 2: Choose JPG

Each file shows a WEBP badge, and JPG at 85% is already selected. Choose PNG instead for a logo or an image with a transparent background.
