Is WebP supported by all major web browsers?

Yes. WebP is supported natively by Google Chrome, Apple Safari (iOS & macOS), Mozilla Firefox, Microsoft Edge, and Opera, accounting for over 97.5% of worldwide web users.

Does WebP preserve transparency from PNG files?

Yes. WebP supports lossy and lossless alpha transparency. When converting a transparent PNG to WebP, the transparency is cleanly retained while dropping the file size by up to 80%.

How much smaller are WebP files compared to JPG and PNG?

According to Google's compression studies, WebP lossy images are 25–34% smaller than comparable JPEG images at the same SSIM quality index, and WebP lossless images are 26% smaller than PNGs.

Can I convert WebP files back to JPG or PNG?

Yes. If an application or legacy photo editor cannot open a WebP file, simply upload the WebP here and select JPG or PNG as the target format to download a universally compatible file.

How does converting to WebP improve SEO and Core Web Vitals?

Google PageSpeed Insights specifically recommends serving images in next-gen formats like WebP. WebP accelerates Largest Contentful Paint (LCP) and reduces mobile data consumption, directly improving your site's SEO performance.

Are my files uploaded to ToolBuddy servers?

No. Conversion happens entirely inside your browser's local sandbox using the browser's native image encoders. Your files remain confidential on your device.
