About PNG to WebP Converter.
Oversized PNGs are one of the most common causes of slow pages: a screenshot or hero graphic exported as PNG is routinely 3-5× heavier than it needs to be. Converting to WebP typically cuts 25–35% (often more) with no visible difference, and every modern browser renders it natively. This converter runs entirely client-side — drop a PNG, get a WebP at full resolution with transparency intact, and download instantly. Ideal for web developers, bloggers, and store owners chasing Core Web Vitals.
Frequently asked questions.
Why convert PNG to WebP?
WebP files are typically 25–35% smaller than equivalent PNGs (often far smaller for photos), which directly speeds up page loads and improves Core Web Vitals — a ranking factor. Every current browser supports WebP.
Is transparency preserved?
Yes. WebP fully supports alpha transparency, so transparent PNGs (logos, UI assets, cutouts) convert cleanly.
Should I still keep the PNG original?
Keep the PNG as your editing master. Serve the WebP on your website. Re-encoding a WebP repeatedly compounds quality loss, just like JPG.
When should I NOT use WebP?
When the image must open in legacy desktop software or be emailed to unknown recipients — PNG/JPG remain the safest interchange formats outside the browser.
