SRCSET, How to Mass Convert Image Files to WEBP Format in Windows

Make the Web Faster.

This is exactly the title that google developers use to introduce and promote the webp format and other tools / techniques to help you make faster web sites in this page : https://developers.google.com/speed .

As i already said one of the tools is the webp format that google devs are already part of its development and you can download and use them from this page for your operating system: https://developers.google.com/speed/webp/docs/precompiled

How can we convert our old images to Webp images?

In windows and in Linux i know there is not any front end utility available yet (i am planning to create one open source to help, but in the future) and until this time as usual the solution will be a script file as you can see it converting 2 images in the picture below.

Windows Script to Mass Convert Images to Webp format.

Create a batch file (a batch file is a text file without the .txt extension but .bat instead and you should have uncheck the hide well known extensions from explorer options ) and add this code inside. this batch file should be in the same folder with all the jpg files you want to convert.

@echo off

cd /d "%cd%"

for %%i in (*.jpg) do cwebp %%i -o %%i.webp && @echo "Converting: %%i"

@echo Done !

pause

Of course you should have the batch file inside the folder of jpg images you want to convert and if you want to convert png you should change the (*.jpg) to (*.png).

Personal i have create all the necessary different batch files for the available image formats that the cwebp utility can convert (JPEG, PNG, TIFF, GIF) with the name jpg2webp.bat, jpeg2webp.bat, png2webp.bat , gif2webp.bat and tiff2webp.bat and i have put them with all the other portable command line utilities i am using like the ffmpeg, youtube-dl etc (because i have add this folder in environment path of windows) and i am calling them from any folder i have old images that i want to convert by typing only the name. for example: jpg2webp

If you are boring to copy paste the code you can download all the batch files from: Here

Also i suggest to enable the command prompt with right click because it helps a lot. If you don't have the registry hack that enables the command prompt with right click, download it from: Here

If you want to revert the previous registry hack use this registry instead.

But don't worry about this registry change, it doesn't change anything until the last update of April 2021 in Windows 10 or Windows 7.
