Frequently asked questions
How do I convert PNG to WebP?
Drop your PNG file into the converter above, adjust the quality if needed, and click "Convert to WebP". The conversion happens entirely in your browser. Your file is never uploaded to any server.
Is the PNG to WebP conversion lossless?
WebP is a lossy format. Quality is controllable from 1–100% (default 92%); at recommended settings the result is visually close to the source for most photos.
Is there a file size limit?
The tool can handle files up to about 20 MB per image. Since processing happens in your browser, the practical limit is your device's available memory. Most modern devices can comfortably batch-convert dozens of images at once.
Are my PNG files uploaded to your servers?
No. All PNG to WebP conversion happens entirely client-side. Conversion uses the Canvas API. Your files never leave your browser.
