Convert Image to WebP

Turn any image into a WebP file. WebP typically compresses 25 to 35 percent smaller than JPG at similar quality, with support for transparency. Ideal for web pages, app assets, and anywhere file size matters.

Smaller fileHigher quality

Smaller file size

WebP is usually 25 to 35 percent smaller than JPG at the same visual quality, and dramatically smaller than PNG for photos with transparency.

Transparency support

Unlike JPG, WebP supports alpha channels. Convert a transparent PNG to WebP and the transparency carries over.

Better page speed

Smaller images mean faster page loads and better Core Web Vitals scores. Google ranks fast pages higher in mobile search.

Wide browser support

Chrome, Edge, Firefox, Safari 14+, and all modern mobile browsers render WebP natively.

FAQ

Will my WebP look the same as the original?

At quality 80 or higher, the difference is usually invisible on screen. WebP compression artifacts are also less obvious than JPG artifacts because the algorithm is more modern.

Can older software open WebP?

Most modern image viewers and editors handle WebP. Older Photoshop versions (before 2022) need a plugin. If you need maximum compatibility, convert to JPG or PNG instead.

Does WebP keep transparency from PNG?

Yes. WebP supports a full alpha channel like PNG. Transparent areas stay transparent in the converted file.

How much smaller will my files be?

For typical photos, expect 25 to 35 percent smaller than JPG. For images with transparency, WebP is usually 50 to 80 percent smaller than PNG.

Is WebP good for printing?

WebP is designed for screens, not print. For print workflows, JPG or PNG remains the safer choice.
