How to convert PNG to WebP online

WebP images are typically 25–35% smaller than PNGs at the same visual quality, making the conversion one of the highest-ROI optimizations for web performance. Every modern browser supports WebP, and the format supports both lossless and lossy compression as well as alpha transparency. This guide shows how to convert a PNG to WebP in seconds using the quickhelp.dev Image Converter — no Photoshop, no command line, no installation required.

Step-by-step guide

1. Upload your PNG: Open quickhelp.dev/image-converter, click the file picker, and select your PNG. The source format is detected automatically.
2. Select WebP as output: Choose 'webp' from the output format dropdown. Set quality to 80 (a good balance between file size and sharpness — increase for print, decrease for thumbnails).
3. Convert and download: Click Run. A preview of the converted WebP appears along with the file size. Click Download to save it.

Frequently asked questions

Does PNG to WebP conversion lose quality?

At quality 80 the difference is imperceptible to most viewers. For pixel-perfect accuracy (e.g., icons or screenshots with sharp text) use quality 95+ or enable lossless WebP via the API.

Does WebP support transparency like PNG?

Yes. WebP supports alpha transparency. Your converted file will preserve any transparent areas from the original PNG.
