JPEG has been the standard for photographic images on the web for over 25 years, but WebP closes that gap decisively. At the same perceptual quality — measured by metrics like SSIM — WebP produces files 25–34% smaller than JPEG. For a website with ten product photos averaging 200 KB each, switching to WebP saves roughly 500 KB per page load, directly improving Google's Core Web Vitals LCP score.
The difference compounds at scale. An e-commerce site with a thousand product images running at 180 KB average JPEG size carries 180 MB of image data. The same library in WebP at equivalent quality drops to around 120–130 MB — faster serving, lower CDN egress costs, and a measurably better experience for users on mobile connections.
This converter processes your photos entirely inside your browser — no file is sent to any server. Drop in a single hero image or an entire batch of product shots; each one is converted independently so an error on one file never affects the rest.
Frequently asked questions
Typically 25–34% smaller at the same visual quality. The exact saving depends on the image content — photos with lots of fine detail (grass, hair, textured surfaces) see the biggest gains, while flat or low-contrast images see less. You can fine-tune the trade-off with the quality slider.
At 80% quality and above, the difference is imperceptible in normal use. WebP's compression algorithm is simply more efficient — it achieves the same perceived quality at a lower file size. Side-by-side at 1:1 zoom you may see minor differences in high-frequency detail, but at typical display sizes the images are indistinguishable.
Yes. Drop multiple files into the upload area or use the file picker with multi-select. Each photo is processed independently in parallel — a batch of 20 photos converts in roughly the same time as 3 or 4, limited only by your device's CPU.
All major modern browsers support WebP natively: Chrome (since 2011), Firefox (since 2019), Edge, and Safari (since version 14, released 2020). Coverage across global web traffic is above 95%. WebP is safe to deploy without fallbacks on any mainstream platform.
