PNG to WEBP: smaller files with transparency intact
WEBP keeps the transparency and sharp edges of a PNG while cutting the file size substantially. It is the simplest speed upgrade for image-heavy pages.
Why PNG files get so large
PNG is lossless, which means it stores the exact value of every pixel. Screenshots, icons, logos and interface graphics all reproduce perfectly, but the files grow quickly, especially on a page that uses dozens of them.
For a website, that size turns directly into slower loading, higher bandwidth costs and a worse experience on mobile connections.
What WEBP keeps from the PNG
WEBP supports full alpha transparency, so cut-outs, logos and rounded corners stay clean. It also handles sharp lines and flat colour well, which makes it a good fit for interface graphics and text.
You are not trading transparency for size, which is the usual compromise when PNG is converted to JPEG.
Where the saving comes from
Typical savings range from around 30 to 60 percent depending on the image, and the visual result is usually indistinguishable at normal viewing size.
Every modern browser renders WEBP natively, so the smaller file is served directly without plugins or fallbacks for current visitors.
A practical workflow
Keep the PNG as your master copy and convert a WEBP for the site. If the layout changes or the image must be edited later, you still have the lossless original to work from.
The conversion happens locally in your browser, so nothing is uploaded.
