Have you ever uploaded images to your website only to notice the page loading slowly?If so, you’re not alone, and the culprit is often the image format you’re using.
While PNG files offer great quality and support transparency, they can also be quite large in file size. That extra weight adds up quickly, especially on mobile devices and slower networks.
That’s where WebP comes in.
WebP is an image format developed by Google with one goal in mind: smaller file size, same or better image quality.
Compared to PNG:
WebP images load much faster
They take less storage and bandwidth
They help improve user experience and site performance
You can think of WebP as the optimized successor to PNG, ideal for modern websites.
If you want a broader comparison of WebP against other formats like JPG, check out our article on JPG vs WebP.
PNG isn’t useless, far from it.These are cases where PNG is still a valid choice:
Images that need perfect transparency
Graphics with hard edges or text
Screenshots where artifacts matter
Situations where compatibility with very old browsers is required
Think of PNG as the reliable old friend, great quality, widely supported, but a bit heavy.
The good news? Converting is fast and simple.
Upload your PNG file
Choose WebP as the output format
Convert and download the optimized image
This helps make your site:
faster to load
more responsive on mobile
more efficient overall
If speed and performance matter (and they always do), converting PNG to WebP is one of the easiest wins you can get, often with zero visual compromise.
