Convert WebP to PNG

No. PNG is a lossless format, so the decoded pixels from your WebP file are saved exactly as-is. If your WebP was lossy-compressed, the already-decoded image is preserved without further degradation.

Almost always yes. WebP typically produces files 25-35% smaller than PNG for equivalent quality. Converting back to PNG reverses that compression advantage, so expect a larger file.

There is no server-side limit because nothing is uploaded. The practical limit depends on your device's available RAM. Most devices handle images up to 100 MP without issues.

Once the app has loaded, it can run offline. All processing uses WebAssembly locally, so no internet connection is needed after the initial page load.
