About the PNG to WebP converter
This free PNG to WebP converter turns a PNG into the smallest modern image format — and unlike JPG, it keeps your transparency. Upload the file, set the quality, download the WebP. It all happens in your browser.
WebP is the format to use on a website. A PNG logo that weighs 400 KB commonly lands around 40 KB as WebP, with the transparent background intact. That is the single easiest page-speed win most sites never take.
How to convert PNG to WebP
- Drop your PNG onto the upload area, or click to choose it.
- Set Download format to WebP.
- Adjust the Quality slider — 90% keeps it visually identical.
- Click Convert PNG to WebP and download.
Why WebP beats both PNG and JPG
- Smaller than JPG at the same visible quality, typically by 25–35%.
- Much smaller than PNG, often by 70% or more.
- Keeps transparency, which JPG cannot do at all.
- Handles both photographs and flat graphics well.
Practically, WebP does the job of PNG and JPG together, at a smaller size than either.
When not to use WebP
Support is excellent in browsers — Chrome, Firefox, Safari and Edge have all handled WebP for years. The gaps are elsewhere:
- Some government and bank upload portals only accept JPG or PNG.
- Older desktop software and a few printers do not recognise it.
- A few WhatsApp and email clients handle it awkwardly.
Rule of thumb: WebP for your website, JPG or PNG for anything you have to upload or send to someone else.
