PNG → WEBP

Yes, WebP supports both lossy and lossless compression with alpha transparency. Your transparent PNG will maintain its transparency after conversion to WebP.

It depends on the codecs involved. If both PNG and WEBP are lossy, the pixels are re-encoded and a small amount of detail is discarded — invisible at default quality settings on photographs. If WEBP is lossless (PNG, TIFF, BMP) the output keeps every pixel of the decoded PNG exactly, but cannot recover detail that PNG had already compressed away.

Every modern browser since 2020 — Chrome, Firefox, Safari 14+, Edge, Opera — supports WebP natively. Pair it with a <picture> fallback for very old browsers.

WebP lossless files are typically 26% smaller than PNG. With lossy compression, savings can reach 60-80% while maintaining visually similar quality.

Often yes, especially when WEBP is lossless. PNG tuned for efficient web delivery will usually produce smaller files than WEBP's default settings. If file size matters, drop the quality in Advanced or pick a more compressed target format instead.

No. WebP supports the same 8-bit alpha channel as PNG, and the conversion preserves it bit-exact in lossless mode.

Yes, converting PNG to WebP is completely free on KaijuConverter. No registration or software installation is required.

KaijuConverter uploads over HTTPS, processes the image in an isolated container and deletes both the source and the output within two hours. No account is required, file contents are never logged, and we do not use uploads to train any model. For confidential material, the paid plan includes a data-processing agreement.

Lossless WebP is usually 25-35% smaller than the equivalent PNG. Lossy WebP at q=85 cuts that to 60-75% smaller than the source.
