How do I convert multiple png to webp on a computer Windows 11?

Hello,

You're correct, PNG image conversion to WebP is an excellent method of reducing file size by a considerable amount without any loss of image quality. It's particularly useful for large groups like yours.

To make it convenient for you, Coding India Lab offers a robust batch image converter tool that allows converting hundreds of PNG files to WebP format simultaneously, from your desktop. Key features are:

Batch processing for 500+ photos

Ultra-fast conversion

Dramatic file size reduction with very little quality loss

Fully supported on Windows 11

Easy-to-use drag-and-drop interface

We'd be more than happy to offer you access to the tool and walk you through the instant setup if you're interested.

A Photoshop action is a set of automated steps that can be recorded, saved, and replayed in Adobe Photoshop. When you create an action to convert PNG files to WebP, it allows you to batch-process multiple files with a single click.

However, it can be difficult to make changes or modify it without re-recording the entire process once the action is started.  In addition,  actions can be useful for small batches of files, they may not be the most efficient way to process large numbers of files. This is because Photoshop needs to load each file individually, which can slow down the conversion process.

In contrast, using a command-line tool or a dedicated PNG to WebP converter like cwebp can offer more flexibility, efficiency, and customization options when converting PNG files to WebP.

In order to save trouble, I used Microsoft Paint, which comes with Windows, to convert PNG to WebP in batches. Although the method is a bit clumsy, it can really be done! Here I share the steps and real experience with you.

1. Open a PNG file
2. Right-click the PNG file directly and select "Open with Paint". The paint tool that comes with Windows 11 supports saving in multiple formats.
   Save as WebP
3. In Paint, click "File" in the upper left corner, then select "Save As" and find the WebP format (Windows 11 supports this format).
4. Save the file to the folder you want.
5. If there are many pictures, you need to repeat the above steps one by one. Manually open and save as, and then do the next one.

At that time, I had about a dozen pictures that needed to be converted, so I tried this method. Although it is a bit slow to operate one by one, it is better than the system's built-in tools, which are simple and direct. After the WebP format came out, the size is indeed much smaller, which is still very effective in saving space.

Converting PNG to WebP on a Windows 11 using tools like cwebp definitely has its perks, but there are a few downsides you might run into based on my rounded-up experiences. While you can convert images one by one easily, doing it in bulk requires some extra steps—like writing a script or using batch files. This can be a headache if you’ve got a ton of images.

The quality control with the -q parameter is great, but it can be confusing to figure out what quality setting works best for your needs. You might end up doing a lot of test conversions before you hit the sweet spot. Sometimes, you might need to install additional software or dependencies depending on how you want to use cwebp. It’s not as straightforward as dragging and dropping into an app.

You can convert one by one with the photoshop app. For bulk png to webp conversion, you can try the free command line tools instead, such as cwebp.  It is a free tool provided by Google as part of the WebP library. It is used to convert images from various formats (such as PNG, JPEG, or TIFF) into the WebP format, which is a modern image format designed for smaller file sizes and better compression efficiency without sacrificing quality.

Below is an example to convert png to webp in windows 11 with cwebp:

cwebp -q 80 input.png -o output.webp

The -q parameter specifies the compression quality (0-100, default is 75)

More than 500 images is indeed a big project! If you don't want to use third-party tools, some of the built-in functions and simple scripts of Windows 11 can also handle batch conversion. Windows comes with PowerShell, you can write a script to batch process images.

The sample script can call the System.Drawing function to convert PNG to WebP (you need to learn some scripting yourself, or find ready-made code online to modify it).

Advantages: fully automatic operation, completed in one go

Disadvantages: scripts need to be written and debugged.

About converting multiple PNG to WebP on Windows 11. I once tried a sketchy freeware converter because I thought it would be quick and easy. I ended up with a bunch of images that looked faded and washed out. Lesson learned: stick to reputable tools like GIMP, or even Microsoft's built-in Photos app if you’re looking for something simple.

After I converted a batch of images, I realized they were all saved with the same generic name, which made it impossible to sort through them. I had to rename everything manually! Now, I always set a naming template before converting.
