How to convert JPG to WebP
- Add your JPG images. Drop them onto the box above or tap to choose files. WebP is already selected as the output format.
- Set the quality. It starts at 92%. For web pages, try something around 80% and compare.
- Press Convert. The images are converted one after another, with a progress bar for larger batches.
- Compare the sizes. Each file shows its size before and after, with the saving.
- Download single files or the whole batch as a ZIP, ready to upload to your site.

Why WebP helps your website
Images are usually the heaviest part of a web page. Smaller images mean pages load faster, especially on mobile connections, and page speed feeds into Google's Core Web Vitals, including Largest Contentful Paint, which is often a large photo at the top of the page. Lighter pages also use less of your visitors' data and less bandwidth on your hosting plan.
WebP gets there by using more modern compression than JPG, and it can also hold transparency, which JPG can't. Many content management systems and site builders now accept WebP uploads directly.
Before you switch every image
A few practical points worth checking first:
- Keep the originals. WebP is great for publishing, but JPG is still the better archive and editing format, and some tools you use offline may not open WebP.
- Resize first. Converting a 4000-pixel-wide photo to WebP still leaves a very large image. Bring it down to the width your site actually displays with the image resizer, then convert.
- Check where else the image goes. Images you also send by email, attach to documents or share with clients are safer as JPG. If someone can't open a WebP, the WebP to JPG converter turns it back.
Finding the right quality for your site
There isn't one correct quality number, because photos behave differently. A simple way to choose:
- Convert one typical image from your site at 92%, then again at 80% and 70%.
- Open each version at the size it will appear on your page and compare them with the original.
- Pick the lowest setting where you can't see a difference, then convert the rest of the batch at that setting.
Photos with lots of fine texture, such as grass, fabric or hair, usually need a higher setting than smooth images like skies or studio product shots. Images containing text, such as banners with a headline, also benefit from staying at the higher end.
Why use Fileora's JPG to WebP converter
The conversion runs entirely in your browser, so your images are never uploaded. That's faster for large batches, and it means client photos and unpublished product shots stay on your machine.
It's free, has no sign-up or watermark, and there's no limit on how many images you convert. It works on a phone or tablet too, although a computer is more comfortable for big batches.
If you need a specific file size rather than a specific format, the image compressor can squeeze an image under a target such as 100KB.
