WebP to JPG — convert saved WebP images in bulk

You save an image from a website and it comes down as .webp. Older photo viewers will not open it, and upload forms — a marketplace listing, a job application, a government portal — say "JPG or PNG only". So it needs to become a JPG.

Why you keep getting WebP

WebP is Google's image format for the web. At the same quality it is smaller than JPG, so many sites now serve their images as WebP. When you right-click and save, you get exactly the file the page was showing.

Viewing it is fine. It is when you re-upload or edit it that you run into places that still only take JPG.

Converting many at once

• Drop all the WebP files into Bulk Image Resizer. There is no limit on the number.
• Under Format, choose JPEG.
• Leave size on Keep original to change only the format.
• Quality 0.80 (the default) is enough; raise it to about 0.9 to stay closer to the original.
• Press Convert, then save files one by one or use Download as zip.

Nothing is uploaded. The conversion happens inside your browser.

Why the JPG is bigger

Converting WebP to JPG usually makes the file a little larger, because WebP packs the same image into fewer bytes. If size matters, shrink while you convert: choose Long edge and enter, say, 1600 px — plenty for a blog or a listing. See how many pixels to resize to.

WebP is also already compressed, so converting compresses it a second time. Keep quality at 0.8 or above to avoid stacking artefacts.

Transparency and animated WebP

• A WebP with a transparent background gets a white background as a JPG, because JPG cannot store transparency. Choose PNG if you need to keep it.
• An animated WebP becomes a still image of its first frame.

On a phone

It works the same way in a phone browser, without an app: pick the WebP files from your photos, convert, and the JPGs go to your downloads.
