Why convert PNG to WebP?
PNG files can be very large, especially screenshots and photographic images saved as PNG. WebP keeps the transparency that makes PNG useful for logos and overlays, but compresses far more efficiently, so pages load faster and use less data.
Keeping transparency
Transparent areas in your PNG stay transparent in the WebP. After converting, preview the result on both a light and a dark background to make sure edges look clean. If you need a flat background instead, use the Convert Image and choose JPG as the output.
Which quality should I use?
| Image type | Suggested quality |
|---|---|
| Logos and UI icons | 90 to 100% |
| Screenshots with text | 85 to 90% |
| Illustrations | 80 to 90% |
| Photos saved as PNG | 70 to 85% |
When to keep PNG
Keep the PNG when you still need to edit the image, when you need exact pixels, or when the image is a tiny icon that will not shrink much. Convert a copy to WebP for your website and store the PNG as your master file.
Frequently Asked Questions
Does PNG to WebP keep transparency?
Yes. Alpha transparency is carried over to the WebP file.
Will the file always be smaller?
Photos and screenshots shrink a lot. Tiny, flat-colour icons can occasionally get larger, and the result size shown beside each file tells you.
Is the conversion lossless?
No. This tool creates lossy WebP at the quality you choose. Keep your PNG if you need a pixel-perfect master.
Can I convert animated PNG?
Only the first frame is converted, because the output is a single still image.
Is there a file limit?
Up to 30 files per batch, 25 MB each.
