To learn how to convert WebP to JPG on Windows, the fastest native method is opening the file in Microsoft Paint and saving it as a JPEG. If you want direct control over the output quality slider without installing anything, use the in-browser WebP to JPG converter. Both methods give you an image you can attach to an email, edit in older versions of Photoshop, or upload to forms that reject WebP files.
Which conversion method should you choose?
Windows handles WebP files differently depending on your operating system version. While modern browsers render WebP without trouble, legacy photo viewers, print shops, and desktop editors often fail to open them. Choosing the right route comes down to how many files you have and how much quality control you need.
- Use an in-browser converter: Best when you need to inspect visual quality before saving, balance file size with an explicit quality slider, or avoid changing native app settings.
- Use Microsoft Paint: Best for a single file on Windows 10 or Windows 11 when you do not have an active internet connection.
- Use the Windows Photos app: Best when you are already reviewing your image library and need to export a quick copy.
- Use a batch processing tool: Best when you downloaded dozens of product photos or wallpaper assets from the web and need them converted together.
Method 1: Convert WebP to JPG online with AtomnyX
Using the free in-browser WebP to JPEG converter allows you to convert files directly inside your browser without uploading your images to an external server. The tool handles one file at a time and provides a live preview alongside an adjustable quality slider.
- Navigate to the converter in any browser like Chrome, Edge, or Firefox.
- Drag your WebP file into the drop zone, or click to select it from File Explorer.
- Review the live preview to verify the image rendered properly.
- Adjust the quality slider. A setting between 90 and 95 preserves nearly all visible detail while keeping file sizes reasonable.
- Click to download your new JPG directly to your PC.
Because WebP images are typically 25% to 40% smaller than equivalent JPGs, converting a 150 KB WebP might produce a 220 KB JPG at maximum quality. If your output file ends up larger than your destination allows, you can lower the slider to between 75 and 85 or pass the result through a dedicated JPG compressor.
Method 2: Convert WebP to JPG using Microsoft Paint
Microsoft Paint comes preinstalled on all Windows versions. Modern editions on Windows 10 and Windows 11 read WebP files natively, making Paint a reliable offline fallback.
- Right-click the WebP file in File Explorer.
- Hover over Open with and select Paint.
- Click the File menu in the top-left corner.
- Hover over Save as, then click JPEG picture.
- Choose your destination folder, name the file, and click Save.
Paint does not offer a compression slider when saving JPEGs. It applies a fixed compression rate, which works fine for quick tasks but gives you no control over final file weight.
Method 3: Export from the Windows Photos app
The default Photos app on Windows 11 allows you to export existing images into alternative formats. If you are on Windows 10, this app might require the free WebP Image Extensions package from the Microsoft Store before it can display the original file.
- Double-click the WebP file to open it in the default Photos viewer.
- Click the three dots (...) located in the top menu bar to open additional options.
- Select Save as from the dropdown menu.
- In the file dialog window, look for the Save as type dropdown at the bottom.
- Change the selection from WebP to .jpg or .jpeg, then click Save.
Method 4: Batch convert WebP files on a PC
Converting dozens of files one by one in Paint takes too long. If you downloaded a large set of images, running them through a bulk utility saves significant time.
- Open the Bulk Image Compressor in your web browser.
- Select or drag your entire batch of WebP files into the processing area.
- Set the target export format to JPG and configure your preferred balance between compression and visual clarity.
- Process the batch and download the converted images to your local drive as a single archive or individual files.
If you also work with modern mobile image formats on your desktop, similar offline workflows apply. You can learn more about managing mobile photos on your PC in our guide on how to convert HEIC to JPG on Windows.
Common problems and fixes
Converting formats on a PC is generally straightforward, but older Windows installations and certain image types present edge cases.
Paint or Photos refuses to open the WebP file
Windows 10 and older releases lack native support for WebP out of the box. If double-clicking the file gives an error saying the file cannot be opened, you have two options. You can install the official WebP Image Extensions from the Microsoft Store, or bypass system limitations entirely by converting the image in your browser using an online tool.
The converted JPG file is much larger than the original WebP
WebP uses advanced predictive encoding, meaning it packs similar visual data into 25% to 40% less space than standard JPEG compression. When you transition from WebP to JPG, the encoding structure changes. To prevent huge file jumps, keep your export quality between 80 and 85 instead of setting it to 100.
The image background turned black
Unlike JPG, the WebP format supports transparent backgrounds. The JPG format has no alpha channel. When you convert a transparent WebP graphic, such as an isolated product photo or a company logo, the transparent areas default to solid black or solid white. If you need to preserve background transparency, convert the file using a WebP to PNG converter instead.
Frequently Asked Questions
Can you convert WebP to JPG?
Yes. You can convert WebP to JPG using built-in Windows software like Microsoft Paint, default photo viewing applications, or in-browser conversion utilities that require no file installations.
Does converting WebP to JPG lose quality?
Yes. Converting between two lossy formats introduces a small amount of quality loss during re-encoding. To keep this loss imperceptible to the human eye, set your converter quality slider to between 90 and 95. If the original WebP was encoded using lossless compression, saving to a JPG at 95 quality preserves nearly all original detail.
Why do images save as WebP instead of JPG?
Websites serve WebP files because they load faster and use less bandwidth than older image formats. When you right-click an image online and click "Save image as," your browser downloads the exact asset the server delivered, which is frequently WebP.
How do you convert WebP to JPG on Windows 11 without extra software?
On Windows 11, right-click the WebP file, choose Open with, and select Paint. From there, click File, hover over Save as, choose JPEG picture, and click Save. The file converts immediately without requiring downloads from the web.
