Why convert PNG to WebP?
How it works
-
Step 1:Add your PNG images

-
Step 2:Convert to WebP
WebP is already picked for you. Set the quality if you like, then press Convert and each image becomes a WebP on your device.
-
Step 3:Download
Save images one by one, or all at once as a .zip.
PNG vs WebP at a glance
How the two formats compare, so you know what to expect.
PNG
Your filesA lossless format that keeps every pixel exactly. Great for screenshots, logos and anything with text or sharp edges.
Best for Screenshots, logos, diagrams, cut-outs with transparency, and master copies you will edit again.
WebP
What you getA modern web format that makes both photos and graphics smaller than JPG or PNG, with transparency.
Best for Websites, apps and online shops: images that should look good and load fast.
| PNG | WebP | |
|---|---|---|
| Compression | Lossless | Lossy or lossless |
| Transparency | Yes | Yes |
| Animation | Rarely (APNG) | Yes |
| Photo file size | Often 3–5× a JPG | 25–35% smaller than JPG |
| Opens in | Everywhere | All modern browsers, most apps |
Questions, answered
Will converting PNG to WebP reduce quality?
WebP is lossy: it trades a little detail you’re unlikely to notice for a much smaller file. At the default quality most people can’t tell the difference, and you can raise the quality if you want to be extra careful.
Will the WebP be smaller than the PNG?
Usually, yes. WebP compresses images more efficiently than PNG, so most files get noticeably smaller. You’ll see the exact size of every file, and how much you saved, as soon as it’s converted.
What happens to transparent backgrounds?
They stay transparent. WebP supports transparency with smooth edges, so logos, icons and cut-outs convert cleanly.
Can I convert lots of PNG files at once?
Yes. Add as many as you like: they’re converted side by side on your device, and you can download them one by one or all together as a .zip.
Do my images leave my device?
No. The PNG to WebP conversion runs entirely in your browser, so your images are never sent anywhere. There’s no sign-up and no limit on how many you convert.
