Convert PNG to WebP
Convert PNG to WebP to make a page load faster. Batches run up to 10 files, 20MB each. Your photo stays put, only your browser touches it.
WebP was built to shrink images without a visible quality hit, and unlike JPG it keeps transparency intact. Swapping a page's PNG images for WebP is one of the simplest ways to cut page weight, since PNG's lossless approach usually stores more data than a photo or icon actually needs.

PNG vs WebP
PNG
PNG keeps transparency and loses nothing on save, which makes it the safe master file to archive. It just was not built to be lightweight on a web page.
WebP
WebP keeps the transparency PNG has, but stores it in a noticeably smaller file most of the time. Some older browsers and legacy editors still handle it inconsistently though.
Why convert PNG to WebP
This is a web delivery move, and the case for it is strong. WebP keeps transparency the same way PNG does, but it usually stores that same image in a noticeably smaller file, which is exactly why swapping page graphics to WebP helps a site load faster. What it will not do: it does not replace PNG as your working file. Older design software still expects PNG, a print shop will ask for it, and anyone archiving original artwork needs that lossless master kept around. A handful of older browsers and image viewers also handle WebP inconsistently. Generate the WebP copy for whatever is going onto a webpage, and leave the PNG untouched everywhere else. Open the WebP once before publishing, just to confirm the transparent areas still look right in a browser.
WebP keeps transparency and is usually much smaller than PNG.
Keep the PNG as your master copy for print or older software.

The conversion happens on your device, nothing is uploaded to a server.
FAQ
Will the file get smaller?
Usually yes, often by a large margin. WebP typically produces a noticeably smaller file than PNG for the same image, which is why it helps a page load faster.
Does transparency survive the conversion?
Yes. WebP supports transparency, so a transparent background in the PNG carries over correctly.
Which format should I keep as the master?
Keep the PNG. It is the safer choice for editing, printing, or opening in older software, so generate WebP copies for your website and leave the PNG untouched.
Should I convert every PNG on my site to WebP at once?
Many site owners do exactly that once a page feels slow, then keep the original PNG files archived in a separate folder in case they are needed again.
