Batch convert PNG to WebP
Convert a whole series of PNG images to WebP in a single operation while keeping transparency, for more compact files on your website or social media.
Why convert a batch of PNGs to WebP?
PNG icons, logos and illustrations are often used in large numbers on a single site (feature icons, avatars, pictograms). Converting them to WebP in bulk reduces their total size while keeping transparency, which speeds up page loading with no visual loss.
Is the transparency of my PNGs preserved after conversion?
Yes, the WebP format supports an alpha channel just like PNG: your images' transparency is fully preserved during conversion.
Can I mix PNGs of different sizes in the same batch?
Yes, each image is processed independently with its own original dimensions; the images in the batch don't need to be the same size.
The whole batch is processed locally via WebAssembly: your PNG images are never transmitted to a server.
