JPG to WebP Converter
Make your photos smaller and your pages faster. Free and private, right in your browser.
Why convert JPG to WebP?
JPG has been the standard photo format for decades, but WebP does the same job with smaller files. Google's comparison found lossy WebP images 25–34% smaller than JPGs of the same visual quality. For a gallery, product catalogue or blog with dozens of photos, that adds up to a much faster page.
Tools like Google PageSpeed Insights specifically recommend serving images in next-gen formats such as WebP. Converting your JPGs is one of the easiest ways to act on that advice.
How to convert JPG to WebP
Drop your JPG or JPEG files above. WebP is preselected. Leave quality around 80, choose a maximum width that matches how large the image is shown on your site, and click Convert All.
Frequently asked questions
Will converting JPG to WebP lower the quality?
WebP is a lossy format like JPG, but at quality 75–85 the difference is very hard to see while the file is noticeably smaller. Compare the preview before downloading and raise the quality if needed.
Do all browsers support WebP?
Yes, all current browsers support WebP, including Safari since version 14. Very old browsers such as Internet Explorer do not.
Are my files uploaded anywhere?
No. Smushify converts everything inside your browser using WebAssembly. Your files are never sent to a server, so it is safe for private photos, client work and unreleased videos.
Can I convert many files at once?
Yes. Drop in as many files as you like, use "Format for all" and "Quality for all" to set every file in one go, then click Convert All and Download All.
