You right-click a photo that looks like a JPG, choose "Save image as…", and get a .webp file your editor or upload form rejects. Here's why, and how to fix it.
It doesn't convert anything. Chrome tells servers it accepts WebP and AVIF (in the Accept header), and many sites and CDNs answer with the smallest format the browser supports. The ".jpg" you see in a URL is just a name. You can't switch this off in Chrome or Edge settings.
Open the image in a new tab. If the URL has parameters like format=webp, fm=webp or f=auto, change them to jpg and reload. Imgix, Unsplash and Cloudinary-style CDNs will usually serve a real JPEG.
magick input.webp output.jpg (ImageMagick) or dwebp input.webp -o output.png.A "save image as type" extension adds JPG/PNG choices to the right-click menu and converts locally. Watch for two problems that show up in reviews: tools that write .jfif instead of .jpg, and tools that later added paywalls or affiliate redirects.
PixLasso adds Right-click → Save image as JPG / PNG / WebP, converts on your computer, writes a true .jpg, and that feature is free.
For dozens of images — a product gallery, a moodboard — use a bulk downloader that converts during download. In PixLasso choose Save as: JPG and Output: One ZIP file (Pro, one payment). Transparent PNG/WebP images get a white background when converted to JPG; choose PNG to keep transparency.
Same story: newer sites serve AVIF to browsers that support it. The same methods work — Paint and Preview open AVIF on current Windows/macOS, and PixLasso converts AVIF to JPG/PNG like WebP.
Updated October 2026. Written by the developer of PixLasso — the extension is mentioned where it genuinely helps, alongside free methods.
