What This Tool Does

It converts images to WebP format, or converts WebP files to JPG or PNG. Upload your image, choose the direction, and download the converted file.

WebP is a modern image format developed by Google in 2010 and now supported by all major browsers. It produces files that are roughly 25 to 35 percent smaller than equivalent JPG files at the same visual quality. For websites, that difference translates directly into faster page load times.

How to Use It

• Click Choose Image and select your file.
• Choose the target format: WebP, JPG, or PNG.
• Click Convert.
• Check the before and after file sizes shown.
• Download the converted image.

Why WebP Matters for Websites

Page speed is a ranking factor in Google search. Images are typically the largest files on a webpage, so reducing their size has a direct impact on how fast the page loads. Converting JPG images to WebP before uploading them is one of the most straightforward ways to improve page speed scores.

Google's PageSpeed Insights and Lighthouse audits specifically flag images that are not in next-generation formats like WebP. If you see that recommendation in your performance report, this tool is the fastest way to address it.

The file size comparison shown after conversion lets you see exactly how much smaller the WebP version is before deciding to use it.

Common Uses

• Converting website images from JPG to WebP to improve page load speed
• Converting WebP files received from a designer to JPG for use in documents or email
• Preparing images for Google PageSpeed optimization
• Converting product photos to WebP before uploading to a web store
• Converting PNG graphics to WebP for use in web applications

Browser and Software Support

All modern browsers including Chrome, Firefox, Safari, and Edge support WebP. Mobile browsers on both Android and iOS support it as well.

Where WebP does not work is in older desktop software and some email clients. Microsoft Office versions before 2019 cannot open WebP files. Some older image editing software also lacks support. If you need to share an image via email or use it in Office, JPG or PNG is still the safer choice.

For anything published on the web, WebP is the better option in almost every case.
