Converting WebP to PNG preserves pixels losslessly and restores alpha transparency with PNG's universally supported format. For lossless WebP sources the pixel data transfers exactly; for lossy WebP the existing artifacts become part of the PNG's pixel content.

Lossless conversion in terms of pixels the WebP currently holds. Lossy WebP artifacts stay baked in; PNG doesn't restore what WebP's encoder discarded. File size grows substantially for photographic content since PNG is less efficient on photos.
PNG is supported by every browser, OS, and image tool made in the last 20 years. Zero compatibility concerns.
WebP is Google's 2010 image format based on the VP8 video codec. It offers lossy and lossless modes, full alpha transparency, and animation in a single container. At matched quality it's typically 25–35% smaller than JPG or PNG. Every major browser has supported it since 2020.
PNG is a lossless image format designed to replace GIF. It uses DEFLATE compression, supports an 8-bit alpha channel for full transparency, and preserves every pixel exactly. PNG excels at images with sharp edges, large flat-color regions, text, UI screenshots, and anything you'll re-edit.
No. If the source was lossy WebP, its compression artifacts are part of the pixel data. PNG preserves those pixels exactly; it can't undo the original lossy encode.
Almost always, sometimes by a lot. WebP's compression is more efficient than PNG's for most content, especially photographs.

Yes. The converter runs entirely in your browser using WebAssembly. Your images are never uploaded, never sent to a server, and never leave your device.
There's no hard limit, but because everything runs in your browser you're bounded by available memory. Very large images (over a few hundred megapixels) can hit browser memory limits. Process in smaller batches if you run into issues.
