How to convert JPG and PNG to WEBP for a faster website
Drop in JPG or PNG files, choose a quality and press Convert. Your browser decodes each image and encodes it again as WEBP, the format Google created for lighter web pages. The pixel size stays the same and the files keep their names with .webp at the end. Nothing is uploaded, so you can convert unreleased product shots or client work without sending them to a third party.
The quality slider runs from 10 to 100 and starts at 85. Lower numbers mean smaller files and more visible smoothing in fine textures such as hair, fabric or foliage. PNG images with a transparent background keep that transparency in WEBP, which makes this a good way to shrink logos and cut-out product photos without losing the see-through areas.
Each file is processed on its own, so a large batch takes a little longer but needs no setup. When you convert several images, they come back together in a ZIP that you can unpack straight into your site's media folder or upload in one go through your CMS.
Problems when converting images to WEBP, and fixes
PageSpeed still complains about my images
Switching format solves the "next-gen formats" warning, but not "properly size images". If a photo is 4000 px wide and shown at 800 px, it is still far too big. Resize it to the displayed width first with Resize Image, then convert to WEBP.
The WEBP is bigger than the JPG
This happens at very high quality settings or when the JPG was already strongly compressed. Bring the slider down to 75 to 85 and compare. If the WEBP is still not smaller, keep the JPG for that image.
My CMS or email tool will not accept WEBP
WordPress accepts WEBP uploads from version 5.8, and most modern shop platforms do too. Some older plugins, newsletter tools and desktop email clients still do not display it. Keep JPG versions for email campaigns and anywhere outside your own site.
Colours look a little flatter
Wide colour profiles from newer cameras are converted to standard sRGB when the browser draws the image. On most screens this looks the same. If colour accuracy matters, compare the original and the WEBP side by side before replacing files.
WEBP vs JPG vs PNG on a website
For photos, WEBP usually beats JPG on size at the same visual quality. For graphics with transparency, WEBP is usually far smaller than PNG. That is why it has become the default suggestion of speed testing tools.
JPG still has its place for downloads, email and anything people save and reuse outside the browser. PNG remains the right choice when you need pixel-perfect, lossless graphics such as screenshots for documentation.
Questions
Which quality setting should I use?
85 to 90 percent looks the same as the original for most photos and saves a lot of space. Go lower only if the file must be very small.
Do all browsers support WEBP?
Yes, all current versions of Chrome, Safari, Firefox and Edge display WEBP.
Does converting images to WEBP help SEO?
Indirectly. Google uses page experience signals, including loading speed, and images are often the heaviest part of a page. Lighter images help pages load faster, but they will not lift a page with weak content.
Should I keep both JPG and WEBP versions on my site?
Not anymore for browsers, since all current ones show WEBP. Keep the original JPG or PNG files in your archive so you can re-export them later at a different size or quality.
Are my files uploaded anywhere?
No. The tool runs in your browser and the files never leave your device. Close the tab and nothing is left behind.
