Shrink PNG files to WebP without losing transparency - smaller files, same quality, every modern browser.
PNG-to-WebP is the conversion that pays off the biggest for web delivery. PNGs of UI screenshots, logos, and graphics with transparency often weigh 500 KB to 5 MB; the WebP equivalent is typically 50-80% smaller while keeping the same transparency and visual quality. For sites that serve a lot of UI imagery, this is a meaningful bandwidth and page-load win.
We decode the PNG losslessly, then re-encode as WebP at Q=92. WebP keeps the alpha channel, so transparent backgrounds survive the conversion. Note: WebP supports both lossless and lossy modes; we use the lossy path at high quality, which is what produces the biggest size savings. If you need bit-perfect output, stick with PNG.
PNG is a lossless image format with alpha-channel transparency. Larger than JPG for photos, but ideal for screenshots, logos, and graphics with sharp edges.
WebP is Google's modern image format that beats both JPG and PNG on file size at the same quality. Supports transparency and animation, plays in every recent browser.
