Compress PNG to WebP

PNG files are often huge because the format is lossless. Converting a PNG to WebP usually cuts the size by 50–80% while keeping the image looking identical — and WebP supports transparency, just like PNG.

Frequently asked questions

Does WebP keep PNG transparency?
Yes. WebP supports alpha transparency, so transparent backgrounds in your PNG are preserved after conversion.
Why are my PNG files so large?
PNG is lossless, storing every pixel exactly. That is great for quality but produces big files. WebP gives near-identical quality at a fraction of the size.
How much smaller will my PNG get?
Most PNGs shrink by 50–80% when converted to WebP. Logos and flat-color graphics often compress the most.
