Why convert JPG to WebP?
Switching website photos from JPG to WebP typically cuts their size by a quarter to a third with no visible difference, so your pages load faster.
JPG is the universal photo format. Every device, browser, email client and printer can open it. WebP is Google’s modern web format. It is usually 25–35% smaller than JPG at the same visual quality and supports transparency.
Frequently asked questions
Do all browsers support WebP?
Yes. Every current version of Chrome, Safari, Firefox and Edge displays WebP images.
Are my images uploaded to a server?
No. Every image is processed inside your browser using WebAssembly. Nothing is sent over the internet, which also makes it fast and safe for private photos.
Is it really free? Are there limits?
Yes. It’s free with no sign-up, no watermark and no daily limit. Your own device does the work, so there is no server cost per image.
Is image quality affected?
The default quality setting produces results that look the same as the original. Move the slider to 95–100 for maximum quality.
Does it work on my phone?
Yes. It works in any modern browser on iPhone, Android, Mac, Windows and Chromebook. You can also add it to your home screen and use it offline.
