Why convert images to WebP?

WebP is a modern image format developed by Google that produces files 25–35% smaller than JPG and PNG at the same visual quality. Every major browser — Chrome, Firefox, Safari, Edge — has supported WebP since 2020, making it the best choice for web images today.

PNG to WebP

PNG files are lossless and often large. Converting to WebP significantly reduces file size while preserving full transparency support — unlike JPG, WebP keeps the alpha channel intact.

JPG to WebP

For photos and complex images currently saved as JPG, converting to WebP at 80–85% quality produces a noticeably smaller file with no perceptible quality difference. Faster page loads, better Core Web Vitals scores.

What quality should I use?

85% (default) is a safe choice for almost every image — high quality with meaningful file size reduction. 75% is the sweet spot for maximum compression on photos. Go above 90% only when pixel-perfect accuracy matters.

Frequently Asked Questions

+Are my images uploaded to a server?

No. Conversion uses the Canvas API and runs entirely in your browser. Your files never leave your device.

+How much smaller will my WebP files be?

WebP is typically 25–35% smaller than JPG and PNG at equivalent quality. Results vary by image content — photos compress more than flat graphics.

+Does WebP support transparency?

Yes. Unlike JPG, WebP fully supports alpha transparency. PNG images with transparent backgrounds are converted without any quality loss.

+Will all browsers display WebP images?

Yes. All modern browsers — Chrome, Firefox, Safari (since 2020), and Edge — support WebP. It is safe to use WebP for any website targeting modern users.
