How to Convert WebP Images in Windows 11

Published by Nyau Wai Hoe - Updated on

WebP, developed by Google, is a new image format that has a much more efficient lossless compression than that of JPEG and PNG. WebP images are on average 30% smaller than that of JPG. It’s aimed to reduce page load time and bandwidth usage because users can download the images faster.

Like most other image formats, you can convert WebP images to other image formats such as JPG, PNG or GIF. You can also convert other image formats to WebP if you want to save space. This guide will show you how to convert WebP to JPG or other image format in Windows 11 (single convert or batch convert), or convert other image format to WebP.

If you want to mass convert multiple WebP images to JPG or other format at once, you can use the WebP converter tool (command line tool) by Google. The instruction below will show you how to do so.

WebP images Windows 11

First, download the WebP converter tool by Google from: Click the Download for Windows button to download the zip file.

Once downloaded, extract the folder to anywhere you like, preferably C:\ directory as the instruction below will use C:\ as the example.

WebP Converter Tool Windows 11

Since the WebP converter tool is a command line tool, you will need to use PowerShell, Windows Terminal or Command Prompt to execute the tool via command line. To convert WebP to JPG in bulk, we will use PowerShell commands.

In Windows 11, right-click the Start button and select Windows Terminal (Admin). Windows Terminal and PowerShell are essentially the same, with Windows Terminal being newer and having more features.

Open Windows Terminal Admin Windows 11

In the Windows Terminal window, enter the following commands (you can enter multiple lines by pressing Shift + Enter to go to the next line without executing the command yet).

$dir = "path to the folder where images you want to convert are stored"
$images = Get-ChildItem $dir
foreach ($img in $images) {
$outputName = $img.DirectoryName + "\" + $img.BaseName + ".jpg"
path_to_the_webp_converter_tool_dwebp.exe $img.FullName -o $outputName

For example, the command lines below will convert all WebP images in the C:\images folder to JPG format using the WebP converter tool (dwebp.exe) which I have extracted to C:\libwebp-1.2.4-windows-x64\bin\dwebp.exe.

$dir = "c:\images"
$images = Get-ChildItem $dir
foreach ($img in $images) {
$outputName = $img.DirectoryName + "\" + $img.BaseName + ".jpg"
C:\libwebp-1.2.4-windows-x64\bin\dwebp.exe $img.FullName -o $outputName

Note that the name of the converter tool’s folder may be different from the example above if the there is any newer version of the tool the time you download the tool, or if you extract it to a different location.

After entering all the command lines, press Enter to execute them. The conversion progress will be shown on the terminal as it converts the WebP images.

For example, the command line below will convert the image in C:\images\Bali.jpg with quality set as 50 (with 0 being the worst, 100 being the best quality, and 75 being the default value if not specified) and save the converted image as C:\images\Bali.webp.

To bulk convert JPG or other image format to WebP, follow the steps in the “Batch convert WebP to JPG” section above until the step where you need to enter command line.

$outputName = $img.DirectoryName + "\" + $img.BaseName + ".webp"
C:\libwebp-1.2.4-windows-x64\bin\cwebp.exe $img.FullName -o $outputName

Replace C:\images with the actual directory where the images you want to convert are stored. In addition, replace C:\libwebp-1.2.4-windows-x64\bin\cwebp.exe with the actual path to the webp.exe tool which you have extracted earlier.
