WebP Converter — JPG to WebP & Image Compressor
Big images are the number one reason small business websites load slowly — and slow pages lose visitors and Google rankings. WebP is a modern image format that is typically 25–35% smaller than the same photo as a JPG, at the same quality. Use it to convert JPG to WebP or PNG to WebP: pick your files, set the quality, and download lighter WebP versions — a quick way to compress images online, with no software to install. Everything happens on your own device using your browser: your images are never uploaded anywhere, so this is safe for product photos, client work and anything private.
80% is the sweet spot for photos — much smaller files, no visible quality loss. Go lower (50–70%) for thumbnails, higher (90%+) for hero images.
WebP converter & image compressor FAQs
Are my images uploaded to a server?
No. The conversion is done by your own browser using technology built into this page. Your files never leave your device, there is no upload queue, and you can even use this page offline once it has loaded. That makes it safe for unreleased products and client images.
How much smaller do images get when I convert JPG to WebP?
Photos converted from JPG at 80% quality typically shrink by about a quarter to a third; screenshots and graphics converted from PNG often shrink far more, sometimes 60–80%. The results list shows the exact before/after size for every file, so you can try a lower quality if a file is still too heavy — under 100 KB per image is a good target for web pages.
Will WebP work everywhere my website is viewed?
Yes — WebP has been supported by all major browsers (Chrome, Edge, Firefox, Safari) for years, and WordPress and most website builders accept WebP uploads directly. It is the safe default format for website images today.
