Frequently Asked Questions
Common questions about PNG to WebP conversion
How do I convert PNG to WebP?
Upload your PNG images — up to 20 at once, drag & drop is supported — adjust the quality slider if you like, and the conversion happens instantly in your browser. Download your WebP files individually or all together as a ZIP.
Does WebP support transparency?
Yes. WebP supports alpha transparency just like PNG, and our converter preserves it — transparent pixels stay transparent after conversion, with nothing flattened.
Why convert PNG to WebP?
WebP files are typically 30-50% smaller than PNG at the same visual quality. That means faster page loads, lower bandwidth costs, and better performance scores for your website.
Is it secure?
Your privacy is our priority. All conversion happens locally in your browser — your images are never uploaded to our servers, so they never leave your device.
