WebP is Google’s modern web image format, supported by every current browser. It compresses roughly 25–35% smaller than JPEG at equal visual quality, supports transparency like PNG, and does both lossy and lossless modes — the pragmatic default for images shipped on websites today.
PNG is the standard lossless image format of the web. It compresses without ever degrading quality and supports full alpha transparency, which makes it the default choice for screenshots, logos, UI graphics and any image with sharp edges or text.
Yes — free, unlimited and without watermarks. Conversion runs on your own machine, so there are no server costs behind it.
No. Your browser decodes the WebP file and re-encodes it as PNG locally using the Canvas API. Nothing is transmitted anywhere.
No, and this is worth being clear about. PNG is lossless, so it preserves exactly what it is given — but the compression artefacts already baked into the WebP source are part of those pixels. The file gets larger without the image getting better.
Yes — drop any number of files and convert the whole batch in one click. A single result downloads as a file; a batch arrives as a ZIP, and each row shows the new dimensions and the size change.
PNG writes the decoded pixels without adding further compression loss, but it cannot restore detail already lost in the WebP source. The fresh canvas export also does not copy source metadata or animation.
