How is a PNG image converted to WebP?

The conversion runs on PicPerf's image processing service: your PNG is decoded — including its transparency data — and re-encoded as WebP using high-quality compression settings. The file is processed for the conversion only and never stored.

Does WebP preserve PNG transparency?

Yes. WebP supports alpha transparency, so the transparent areas of your PNG carry over to the WebP version exactly.

How much smaller is WebP than PNG?

Depending on the image, WebP is commonly 25–70% smaller than PNG at a comparable quality. Photographic content sees the biggest savings; simple flat graphics still shrink, just less dramatically.

Will converting PNG to WebP reduce quality?

This tool uses the highest quality settings, so photos come out visually indistinguishable from the original. If you need a guarantee of zero data loss, PNG or a lossless WebP encode is the safer choice — but for images destined for the web, the size savings usually outweigh that concern.

When should I use WebP instead of PNG?

Whenever you're serving images on the web. WebP is supported by every modern browser and delivers the same visuals at a smaller size, which means faster page loads and better Core Web Vitals. Keep PNG for workflows that require a lossless, universally compatible file.
