Why convert PNG to WebP
- Smaller files: a photo or screenshot saved as PNG often becomes a fraction of its size as WebP.
- Transparent areas stay transparent, so logos and cut-outs still sit on any background.
- Every current browser shows WebP, so it is ready for websites, shops and blogs.
- Smaller images make pages load faster, especially on phones and slow connections.
PNG and WebP compared
| Feature | PNG | WebP |
|---|---|---|
| File size | Large for photos, small for flat graphics | Usually the smallest |
| Transparent areas | Yes | Yes |
| Quality | Lossless: every pixel kept | Lossy as ChobiKit saves it, at high quality |
| Opens in | Every browser, app and computer | Every current browser; some older apps and forms refuse it |
ChobiKit saves WebP at high quality: photos look the same, and the file is much smaller.
Before you convert PNG to WebP
- Keep the PNG if you will edit the image again: PNG keeps every pixel exactly.
- For screenshots with small text, look closely at the result; sharp edges can soften slightly.
- Some older apps and online forms don't accept WebP. If a form asks for PNG or JPG, upload that instead.
Frequently asked questions
How do I convert PNG to WebP?
Choose your PNG and press Convert: on this page WebP is already chosen. Then download the WebP file.
Does WebP keep transparency?
Yes. Transparent and see-through parts of the PNG stay transparent in the WebP.
How much smaller is WebP than PNG?
It depends on the picture. Photos saved as PNG often shrink to a small part of their size; simple graphics shrink less. The tool shows the new size, and how much smaller it is, before you download.
Will the WebP look worse?
ChobiKit saves WebP at high quality, so photos look the same. Sharp text or thin lines can soften a little; switch between Original and Result to check.
Can I convert several PNG files at once?
Yes, up to 10 at a time, downloaded together as one ZIP file.
Are my images uploaded?
No. They are converted in your browser and never sent to a server. It is free, with no sign-up and no watermark.
