Why convert PNG to WebP
PNG is lossless and often large. WebP keeps an alpha channel like PNG but compresses far more efficiently, so transparent graphics get much smaller without a visible quality drop.
Smaller images mean faster pages and better search rankings.
How it works
Add your PNG files, pick a quality level, and each image is re-encoded as WebP on your device with its transparency preserved.
Frequently Asked Questions
Are my images uploaded to a server?
No. Every conversion runs locally in your browser using your device's own processor. Your images never leave your computer or phone, and nothing is stored on our servers.
Does WebP keep PNG transparency?
Yes. WebP supports an alpha channel, so transparent areas in your PNG are preserved in the WebP output.
How much smaller will the WebP be?
It varies by image, but WebP is often several times smaller than PNG for the same graphic while looking identical.
Can I convert several images at once?
Yes. Drop or select multiple files and they'll be processed in a controlled queue so your browser stays responsive. Each file shows its own progress, and you can download them individually or all together as a ZIP.
