Smaller Images, Same Quality
Google’s WebP format makes images far lighter than PNG or JPG. Our converter goes further by finding the best setting for every single image.
Smart compression
Tests several quality levels on each image and keeps the smallest one that still looks identical.
Same resolution
Your WebP keeps the exact width and height of the original, even for 24 MP+ photos.
Private by design
Images are converted in your browser and never uploaded anywhere.
Faster websites
Lighter images improve page speed, Core Web Vitals and your PageSpeed score.
Frequently Asked Questions
01Will converting to WebP reduce my image quality?
Not visibly. Smart mode tests several quality levels on every image and picks the smallest file that still looks the same as your original, so photos usually keep a quality of 85 to 92. Choose Lossless mode if you need every pixel kept exactly as it was.
02Does the converter change my image size or resolution?
No. The WebP file always has exactly the same width and height in pixels as your original, even for very large photos. Only the file size gets smaller.
03Are my images uploaded to your server?
No. The conversion runs entirely in your browser using Google’s WebP encoder, so your images never leave your device. This also makes it fast and lets you convert large or private images safely.
04How much smaller will my images be?
PNG photos and screenshots often shrink by 70 to 90 percent. JPG photos typically become 25 to 45 percent smaller, because JPG files are already compressed. The exact saving is shown for every image.
05Which browsers support WebP images?
All modern browsers support WebP, including Chrome, Safari, Edge, Firefox and Opera on desktop and mobile. You can use WebP images on your website without a fallback for nearly all visitors.
06Why use WebP images on my website?
Smaller images make pages load faster, which improves user experience, Core Web Vitals and Google PageSpeed scores. Faster pages can help with search rankings and conversions, especially on mobile.
07Is there a limit on file size?
You can convert up to 30 images at a time, each up to 50 MB and 50 megapixels. Very large images take a little longer because the converter tests several quality levels to find the best result.
