The best way to convert png to webp without losing quality?

[Patalia]

Hi everyone,

I'm trying to convert a batch of PNG images to WebP format on my Windows PC, but I'm not sure where to start. I'm looking for a method that's straightforward and ideally doesn't require too much technical knowledge.

I’ve heard that tools like the Photos app or command-line utilities might work, but I’m not familiar with the process. Could someone please recommend the best way to convert png to webp without losing quality? If possible, I’d really appreciate a step-by-step guide or any tips that could make this easier for a beginner like me.

Thanks a lot for your help! Looking forward to your suggestions.

The Photos app on Windows 11 does support the WebP image format. You can open and view WebP images directly in the Photos app without needing any additional software. In addition, the Photos app has  built-in features for converting PNG to WebP one by one for free.

@Patalia WebP provides a balance between image quality and file size. This will make websites load faster, which is crucial for user experience and SEO. Developers often recommend using WebP for web images because it reduces the file size by up to 30% compared to PNG or JPEG without losing noticeable quality. For website owners, it is an important task to convert png to webp for website publishing.

As the creator of WebP, Google extensively uses and promotes it across its platforms, including Google Search, Google Play Store, and Google Chrome, which natively supports WebP.

WebP supports both lossy and lossless compression. If you go for lossy and set the quality too low, your image might look more like a pixelated mess than a clear picture. Aim for that sweet spot—usually setting quality to around 80-90% is a good starting point.

Sometimes, When converting PNG to WebP on computer, forgetting to check file paths leads to errors. If your PNG is in a protected folder or you accidentally try to write the converted file into a read-only section, the conversion will fail. Always double-check where you're saving those files!

If you are looking for the best PNG to WebP converter, and if you have Photos. Although it doesn't natively support saving as WebP, you can use it for viewing and accessing images effortlessly:

1. Open the PNG file in Photos.
2. Then use the Edit Image feature and make any quick adjustments if desired.
3. While you can't save directly to WebP, you can screenshot and edit to save it as a WebP image using online tools afterward.

@Renataxom You got it wrong. The Photos app is able to open and export WebP to PNG but unable to convert PNG files to WebP. The available output in  the Photos app are JPG, JPEG, TIFF and PNG. Fortunately, you can do this with the built-in Paint app.

The Paint app is a simple graphics editing and conversion program that has been included with Microsoft Windows operating systems since its earliest versions. It allows users to create and edit basic graphics and drawings. Despite its simplicity, Paint has been a popular tool for converting png to webp without losing quality on Windows 11 and Windows 10.

Google also uses and promotes this format extensively on its own platforms, including Google Search, Google Play Store, and Chrome browser, which all natively support WebP. What do you think of the experience of using WebP on your website? Have you tried converting PNG to WebP?

When you're working with graphical tools, you can usually see what your image will look like before you save it. With cwwebp to convert PNG to WebP on Windows computer, you don’t get that instant feedback. You end up having to convert the image, check it out, and then possibly do it all over again if you’re not happy with the results. That can waste a bit of time.

Using Microsoft Paint to convert PNG to WebP is a simple method, but it also has some shortcomings. First, Paint can only convert files one by one, and cannot process them in batches. If you have a lot of pictures to convert, you have to do it one by one, which is troublesome.

Secondly, Paint's functions are relatively limited, and it may not support some advanced settings, such as compression level or quality selection, which is not convenient for users who need fine-tuning. In addition, Paint's interface is relatively simple and sometimes not intuitive enough, so beginners may need time to adapt.

Although Paint is easy to use, if you need to process a large number of pictures or want more control options, you may need to consider other tools. What do you think? Have you tried other methods?

Photos app is not a good way to convert PNG files to WebP. If you've got a whole bunch of PNGs to convert, good luck doing that in Paint! You would have to open each one manually, convert it, and save it again. It's a total time-suck if you're dealing with multiple files. There's no "select all" and convert that you might see in more advanced software. After you save your image as WebP, you'll have to open it in another program to see how it turned out. This means another round of back-and-forth if you want to adjust anything. It can get annoying!

You can try online png to webp converter. Websites such as Convetio provide online conversion functions. You just need to upload the PNG file, select the output format as WebP, click Convert, and download it. This method is especially suitable for people who don't want to install software.

Using online png to webp converters is indeed convenient, but there are also some disadvantages.

1. First, when uploading large files or batches of files, you may be subject to file size and number restrictions, which makes it not suitable for large-scale conversion.
2. Second, it relies on network connection. If the network is unstable, the conversion process may be affected. In addition, for privacy and security reasons, uploading files to third-party websites may be worrying, especially when sensitive content is involved.
