What happens when you convert PNG to WebP
| Compression | Lossless → Lossy or lossless |
|---|---|
| File size | Usually far smaller: often under a fifth of the size for photos |
| Transparency | Kept |
| Metadata | EXIF, GPS location and camera data are not copied to the new file |
| Opens in | all current browsers, Windows 10/11 Photos, macOS 11+ and recent editors; many upload forms and print shops still refuse it |
Sizes are typical values; your files will vary with content and settings.
PNG Portable Network Graphics
PNG stores pixels with lossless DEFLATE compression and a full 8-bit alpha channel. It is the safe default for screenshots, logos, UI assets and anything with sharp edges or text, because every pixel survives exactly as drawn.

WebP is Google's web image format. It supports both lossy and lossless compression plus alpha transparency, and typically produces files 25 to 35 percent smaller than JPG at similar visual quality. Every current browser displays it.

Why convert PNG to WebP?
PNG files usually come from screenshots, design tools and image downloads, where lossless storage keeps edges crisp. Photographs saved as PNG are often 3 to 10 times larger than the same photo as JPG or WebP. Choose WebP to make images load faster on a website while keeping transparency.
PNG to WebP settings
Use the quality slider to balance size against detail; 80 to 90 percent is a good default for WebP. You can also cap the width and height, which resizes large photos in the same step.
Frequently asked questions
Will the WebP lose quality?
WebP uses lossy compression, so some fine detail is discarded to make the file smaller. At the default quality setting the difference is very hard to see. Raise the quality slider if you need the result to stay closer to the PNG original.
Is transparency kept when converting PNG to WebP?
Yes. WebP supports transparency, so transparent areas in your PNG stay transparent.
Will the WebP be smaller than the PNG?
Usually much smaller for photos: as a rough guide, the WebP comes out at around 10% of the PNG's size, depending on the quality setting.
