How to Convert PNG to WebP
- 1
Upload your PNG
Drag and drop or browse to select your PNG file. Transparency is preserved automatically.
- 2
Adjust WebP quality
85% quality is a solid default. WebP at 85% is comparable to JPG at 92% in file size, but with better visual quality and transparency support.

Download the WebP file
Save the converted file. You'll immediately see the size difference — typically 25-35% smaller than the original PNG.
WebP: The Modern Replacement for PNG
Google developed WebP specifically to make the web faster. It achieves 25-35% smaller files than PNG at equivalent quality, and it supports both lossy and lossless compression. More importantly for PNG users, WebP preserves transparency — something JPG can't do.
Browser support is essentially universal now. Chrome, Firefox, Safari, and Edge all handle WebP natively. Safari added support in version 14 (2020), which was the last holdout. The only scenario where WebP causes problems is email clients and very old software that hasn't been updated in years.
For web developers, converting PNG assets to WebP is one of the easiest performance wins available. A page with ten 200KB PNGs serves 2MB of image data. Convert them all to WebP and that drops to 1.3-1.5MB. That's a meaningful improvement in Largest Contentful Paint and overall page load time.
Frequently Asked Questions
Does WebP keep my PNG's transparency?
Yes. WebP supports full alpha channel transparency, just like PNG. Semi-transparent pixels, gradient masks, and complex transparency all convert correctly.
How much smaller is WebP compared to PNG?
Typically 25-35% smaller for equivalent visual quality. The savings vary by image content. Photos see bigger reductions (30-40%). Simple graphics with flat colors see smaller gains (15-25%) because PNG already compresses those efficiently.
Should I use lossy or lossless WebP?
For photos converted from PNG, lossy WebP at 85-90% quality gives the best size reduction with no visible quality loss. For pixel-perfect graphics (icons, UI elements), use lossless WebP to prevent any artifacts around sharp edges.
