Convert PNG to WEBP
About PNG
Portable Network Graphics (PNG) is a raster graphics format that supports lossless data compression, meaning no quality is lost when the file is compressed. Its most notable feature is its support for transparency (the alpha channel), which allows images to have transparent backgrounds. This makes PNG a favorite for web graphics, logos, and icons.
About WEBP
WebP is a modern image format developed by Google to provide superior lossless and lossy compression for images on the web. WebP images are significantly smaller than their JPEG and PNG equivalents, which helps websites load faster and save bandwidth. It also supports transparency and animation, making it a versatile replacement for both JPEG, PNG, and GIF.

Frequently Asked Questions
Is PNG better than JPEG?
It depends on the use case. For photographs, JPEG provides smaller file sizes with minimal perceptible quality loss. For graphics with sharp lines, text, or transparency needs, PNG is superior as it is lossless and supports an alpha channel.
Why are PNG files larger than JPEGs?
PNG files are larger because they use lossless compression. They retain all the original image data, whereas JPEG uses lossy compression to discard data and reduce file size. This makes PNGs higher quality but also larger.
Is WebP supported everywhere?
WebP is now supported by all major modern browsers, including Chrome, Firefox, Safari (version 14 and later), and Edge. While its adoption is widespread, some very old browsers or simple image viewers may not support it, so providing a fallback to JPEG or PNG is sometimes necessary.
How much smaller is WebP compared to JPEG?
According to Google's data, lossy WebP images are typically 25-34% smaller than comparable JPEG images at the same quality index. Lossless WebP images are about 26% smaller than PNGs.
