Why convert PNG to WebP?
WebP produces much smaller files than PNG at similar quality, while still supporting transparency. Smaller images load faster and improve Core Web Vitals, so WebP is the modern default for images on the web — without giving up the alpha channel you rely on with PNG.
Does WebP keep PNG transparency?
Yes. Unlike JPG, WebP supports a full alpha channel, so transparent areas of your PNG are preserved exactly. You get a smaller file and keep the transparency.
How much smaller is WebP than PNG?
WebP is typically 25–35% smaller than a comparable PNG, and often far more for photographic images. Use the quality slider to push the file smaller; lower values trade a little detail for a lighter file.
Is this PNG to WebP converter free and private?
Yes. It is completely free, with no signup, no watermark, and no limit on how many files you convert. Every conversion happens locally on your device, so your images are never uploaded to a server. Read more in our privacy policy.
