- Technical
How PNG to WebP conversion works
PNG is a popular image format known for its lossless quality and transparency support. While PNG files provide excellent image quality, they are often larger than modern image formats.
WebP uses advanced compression technology to significantly reduce file sizes while maintaining high visual quality. During conversion, the image data is optimized and encoded into the WebP format, producing smaller files that load faster on websites and applications.
The result is a modern image format that helps improve website speed, reduce storage requirements, and lower bandwidth consumption.
- Comparision
JPG vs PNG — the honest comparison
Neither format is universally better. The right one depends on what you’re showing and where it lives. JPG wins on file size for photographs; PNG wins on fidelity, edges and transparency. Use this table as a quick decision-maker.
