How to convert PNG or JPG to WebP
Add PNG or JPG files by dragging them in, selecting them or pasting an image. Set the quality, press Convert and download the .webp files one by one or as a ZIP. The tool needs a browser that can create WebP files; if yours cannot, it shows a message instead of a broken file. Current Chrome and Edge can.
Why WebP helps website speed
WebP is designed for the web. Google reports that lossy WebP files are typically 25–34% smaller than comparable JPGs, and lossless WebP about 26% smaller than PNGs. Lighter images download faster, which improves Largest Contentful Paint, a Core Web Vitals measure that search engines consider as part of page experience.
Transparency and quality
Unlike JPG, WebP supports transparency, so a PNG logo with a see-through background stays transparent. For photos, a quality between 75 and 90 usually looks the same as the original at a much smaller size. Because converting from a lossy image adds a little more loss, keep your original files.
A simple workflow for website images
- Resize the picture to the largest size it will be shown at with the image resizer.
- Convert it to WebP here.
- Check the file size in the results list and compare it with the original.
- Upload the WebP to your site, keeping the original PNG or JPG in your archive.
Doing the steps in this order matters: shrinking the pixels first usually saves more than any format change on its own.
Checking the savings
The results list shows each file’s new size, and the summary shows the total before and after for the batch. Savings vary with the image: flat graphics and screenshots often shrink a lot, while already-compressed JPG photos gain less. If a converted file is not noticeably smaller, keep the original.
Bulk conversion
You can add up to 100 files at once, each up to 60 MB, and download the results separately or in one ZIP. A progress popup shows the percentage and lets you cancel.
Compatibility and fallbacks
All current browsers display WebP, but a few older browsers and some desktop apps and print services do not. For websites, this is rarely a problem today, though you can offer a JPG or PNG fallback with the HTML picture element if you need to support older environments. To turn WebP files back into universally accepted formats, use the WebP to JPG converter or WebP to PNG converter.
To shrink dimensions as well, combine this with the image resizer. Your files are processed in your browser and never uploaded.
