It’s up to you to decide which format best suits your needs.

This is not a PNG vs WebP article as it’s about which PNG tools compress a PNG better and which WebP tools compress WebP better. In this article, we look at 17 free PNG and WebP lossless compressor tools (online, command line, desktop GUI) and also find which ones produce the smallest file sizes while preserving image quality. Reducing the image file size as much as possible helps to save bandwidth cost, reduce time to download, and even achieve a higher Google PageSpeed score because “optimize images” is one of the priorities.

You can easily find many tools on the Internet to compress image files but most, if not all of them produce different file sizes. The newer WebP is dual role because you can compress images with either lossless or lossy compression but it’s a bit less compatible than JPEG and PNG. PNG is good on smaller and transparent pictures because it’s lossless and you don’t lose quality. The GIF image format is commonly used for short animated images while JPEG is for higher quality photos using lossy compression to reduce file sizes.
