How to Download WebP Images and Convert Them to JPG

WebP is the default image format on most CDNs in 2026: Cloudflare, Vercel, Shopify, and basically every site that cares about performance. The browser handles WebP natively, which is great. The problem starts when you download a WebP image and try to import it into Keynote, PowerPoint, Photoshop's older versions, or any image tool that still expects JPG or PNG. Some tools just refuse. Others silently break colour profiles. This guide covers the fastest workflow: bulk download every WebP from a page, then batch convert the whole folder to JPG or PNG.

Why everything is WebP now

WebP files are roughly 25-35% smaller than JPG for equivalent visual quality, and 70% smaller than PNG for graphics with sharp edges. Faster pages, lower CDN bills, better Core Web Vitals scores. Every major CDN serves WebP by default to browsers that support it (every modern browser does). On many sites you cannot even ask for the JPG version any more, the original was never stored, only the WebP transcode is.

This is fine for viewing. It is a pain when you actually want to use the file outside the browser.

Step 1: Bulk download every WebP image from the page

The Bulk Image Downloader extension treats WebP as a first-class format. Open the popup on any page, click Scan Page for Images, then in the file type filter check WEBP (uncheck JPG and PNG if you want only WebP). Click Download All or Build ZIP. You now have a folder of .webp files.

If you want both formats in case the page mixed them, leave all filters on. The downloader will save each file with its original extension.

Step 2: Batch convert WebP to JPG or PNG

Once you have the WebP files locally, two options:

Option A: WebP to JPG/PNG Converter Chrome extension. Open the extension, drag your folder of WebP files into it (or select them via the file picker), choose JPG or PNG as the target format, set quality (90 is the sweet spot for JPG: nearly indistinguishable, much smaller than 100), click Convert. The extension runs entirely locally, no upload, no cloud roundtrip.

Option B: macOS Preview or Windows Photos. Open a WebP, use File > Export As (macOS) or Save As (Windows) and pick JPG. Works for one file at a time. Painful for 50.

Option C: Command line with cwebp / dwebp. If you live in a terminal, dwebp input.webp -o output.png works for PNG. For JPG, pipe through ImageMagick: dwebp -o - input.webp | convert - output.jpg. Scriptable for thousands of files but obviously requires the tools installed.

The complete workflow in 60 seconds

1. Navigate to the page with the images you want.
2. Open Bulk Image Downloader, click Scan Page for Images.
3. Filter to file type WEBP and minimum width 500px (skips tracking pixels).
4. Set a filename pattern like {title}-{index} so files are named for the page context.
5. Click Build ZIP. Wait a few seconds, the ZIP downloads.
6. Unzip into a folder.
7. Open the WebP to JPG/PNG Converter, drag the unzipped folder in, pick JPG at 90% quality, click Convert.
8. Done. You have a folder of JPGs ready for any tool.

The whole flow for a 50-image batch takes under a minute and runs entirely on your machine.

What about quality loss?

WebP to JPG is a lossy-to-lossy conversion, so there is some quality cost. In practice, at JPG quality 90 the loss is invisible to the human eye on photographs. For graphics with sharp edges (logos, illustrations, screenshots), prefer PNG as the output format because PNG is lossless. For photographs that will be re-edited, also prefer PNG to avoid stacking lossy passes.

Rule of thumb: photographs to JPG, anything with text or sharp edges to PNG.

What about AVIF?

AVIF is the next-generation format after WebP, offering even smaller files for the same quality. As of 2026, AVIF is increasingly common, especially on Cloudflare-served images. The exact same workflow applies: Bulk Image Downloader detects and saves AVIF files; for converting, you need a tool that handles AVIF input. Several open-source converters now support it, and the local Chrome extension converter ecosystem is catching up.

If AVIF support matters today, check the converter extension's documentation before installing.

FAQ

Can I convert without downloading first? Some online services accept a URL and return a JPG. We do not recommend them because they upload your images to a third-party server. Stick with the local workflow above.

Why does my downloaded WebP look smaller than the on-page image? Sites serve different sizes for different viewports via srcset. Make sure the high-resolution variant is loaded (visible at the actual size you want, not a small thumbnail) before scanning.

Will the converted JPGs have the original metadata? EXIF and basic metadata usually survive. Colour profiles can drift slightly. For colour-critical work, check the output in your editor of choice before committing to large batches.

Is there a way to skip this whole flow? If the website has a built-in download link that offers JPG, use it. Most sites do not.
