Questions and answers
Is lossless WebP smaller than PNG?
Usually yes, often by around a quarter, with exactly the same pixels.
Does WebP keep semi-transparent edges?
Yes. Both lossy and lossless WebP store a full alpha channel, so soft shadows and anti-aliased edges stay smooth.
Is PNG to WebP free?
Yes. Every tool on ImgImage is free to use, with no sign-up, no watermark and no limit on how many files you process.
Are my files uploaded anywhere?
No. Your files are processed by your own browser and never leave your device. Nothing you open here is sent to a server.
Does it work on my phone?
Yes. It works in any modern browser on phones, tablets and computers. Large files are processed faster on a computer.
