Convert PNG to WebP online, free
PNGs are crisp but heavy — a single screenshot can weigh several megabytes. WebP gives you the same pixels (transparency included) at roughly 25–35% smaller file sizes, which means faster websites, quicker uploads, and less storage. Drop your PNG below: the converter is pre-set to WebP at 85% quality, the sweet spot for photos and screenshots. Everything runs locally in your browser — no uploads, no signup, no watermarks.

Tips for the smallest WebP files
Photos → 80–85%
Camera photos and screenshots look identical to PNG at 85% while shedding a third of their weight.
Logos keep transparency
WebP preserves alpha channels, so transparent logos and UI graphics convert losslessly in practice.
Resize first, convert second
A 4000px screenshot displayed at 800px wastes 90% of its bytes. Shrink dimensions before converting.
Frequently asked questions
Will converting PNG to WebP keep transparency?
Yes. WebP supports transparency just like PNG, so transparent backgrounds and logos survive the conversion untouched.
How much smaller is WebP compared to PNG?
Typically 25–35% smaller for photos and screenshots at visually identical quality. Simple graphics with flat colors can shrink even more.
What quality should I use?
85% is the sweet spot for most images. Use 90–95% for images you'll edit further, 75–80% when every kilobyte counts.
Is WebP supported in all browsers?
All modern browsers — Chrome, Edge, Firefox, Safari 14+ — display WebP. Very old software may not, in which case keep a JPG copy using our WebP to JPG converter.
Are my images uploaded anywhere?
No. Conversion runs entirely in your browser. Your files never leave your device — safe even for sensitive screenshots.
