Convert PNG to WebP
Updated Jul 2026
PNG is a lossless format used for screenshots, logos, and UI graphics, while WebP is a newer format built for the web that can shrink those same images dramatically. To convert PNG to WebP, open the file in a converter and export it as WebP. Doing it on your own computer means the image never leaves your machine.

How to convert PNG to WebP
- Open Morphjet and drag in the PNG files you want to convert. Add one image or a whole folder of screenshots and assets at once.
- Choose WebP as the output format, and pick a quality level if you want a smaller file.
- Convert. The WebP files are written next to your originals, and nothing leaves your machine.
PNG vs WebP: what actually changes
| PNG | WebP | |
|---|---|---|
| File size | Larger, since compression is lossless | Smaller, often noticeably less than PNG for the same image |
| Quality | Lossless, no quality loss ever | Lossy, a small trade-off for the smaller file |
| Transparency | Yes | Yes |
| Opens everywhere | Yes, supported by every browser, OS, and image app | Mostly, all modern browsers support it, but some older software and apps still don't |
| Best for | Screenshots, logos, and graphics needing exact pixels | Web pages, where a smaller file means faster loading |
When to convert, and when not to
Convert PNG to WebP when you're publishing images to a website or app and want faster load times without a visible quality hit.
Keep the PNG original if you need pixel-perfect accuracy, like a logo template or a screenshot you'll keep editing, since WebP's lossy compression means repeated re-saves can gradually soften fine detail.
Why not just use an online converter?
Screenshots and UI assets often show things you didn't mean to share, like an open inbox, a customer's name, or an internal dashboard in the background. Uploading a batch of them to an online converter puts all of that on someone else's server, even briefly. Converting on your own computer means those images, and whatever they show, never leave your machine.
Questions
Does converting PNG to WebP lose quality?
A little, since WebP uses lossy compression. For screenshots, logos, and web graphics the difference is usually invisible, but converting back and forth repeatedly will compound the loss.
Will WebP keep transparency like PNG does?
Yes. WebP supports transparency just like PNG, so logos and UI assets with transparent backgrounds convert without any change in how they look.
Do all browsers support WebP?
All current versions of Chrome, Firefox, Safari, and Edge do. A handful of older browsers and some desktop apps still expect PNG or JPG, so it's worth keeping the original around if you're not sure who'll open the file.
Why convert PNG to WebP instead of just keeping PNG?
WebP was built specifically to make web images smaller without looking obviously worse, so pages load faster. If file size doesn't matter or you need pixel-perfect editing, PNG is still the safer choice.
Can I convert PNG to WebP without uploading the files?
Yes. A desktop app like Morphjet converts the images on your own computer, so nothing is sent anywhere, which matters if your screenshots contain anything private.
Morphjet converts PNG, WebP, and 1,800+ other formats, all on your machine. Launching this July.
