Frequently asked questions
Does WebP keep transparency?
Yes. Unlike JPG, WebP supports an alpha channel, so transparent logos and UI elements convert cleanly.
How much smaller will my files get?
Typically 25–80% smaller depending on content — flat-color graphics compress the most. The exact saving is shown next to each converted file.
Is WebP safe to use on my website?
Yes — every modern browser has supported WebP for years. Only very old systems (e.g. IE11) cannot display it.
About this tool
WebP routinely cuts image weight by 25–80% compared to PNG while keeping transparency — which is why PageSpeed Insights keeps recommending it. This converter turns PNGs into WebP right in the browser: drop the files, pick a quality, download the results with a per-file size comparison so you can see the savings immediately. Unlike PNG-to-JPG, transparency is preserved, making WebP the right target for logos and UI assets as well as photos. All modern browsers display WebP; only very old software does not.
