What changes
PNG is lossless and WebP is lossy, so some quality is lost: it shows on hard edges and long gradients.
In our test, a 1600 × 1067 photo took 2.6 MB as PNG and 104 KB as WebP.
Both support transparency, so it’s kept.
WebP supports animation and PNG doesn’t, so several PNG files don’t become an animation: they would have to be joined first.
When it’s worth it
Choose WebP for: Websites, online stores and apps. Usually smaller than JPG at the same quality, with transparency.
Stay with PNG for: Logos, screenshots, and graphics.

Questions
Does converting PNG to WebP lose quality?
Yes. WebP is a lossy format, so some detail is lost.
What is the WebP format?
Google's image format from 2010, with both lossy and lossless modes, later adopted by the W3C as a web recommendation. It beats JPEG and PNG on file size and still adds transparency and animation, which is why most sites use it.
What is the PNG format?
Lossless image format from 1995, standardized as ISO/IEC 15948. It compresses with Deflate and supports an alpha channel and 8 or 16 bits per channel, which is why it’s the default for screenshots, logos and anything that has to stay sharp.
Are the files uploaded?
No. The file is opened in this tab, converted here and saved from here. There’s no account and no watermark.
How many files can be converted at once?
Up to 200 per batch and about 2 GB per file, within the memory this device has available.
