WebP conversion that keeps transparency
The PNG to WebP converter turns PNG images — plus JPG, HEIC, GIF, BMP, TIFF and AVIF sources — into WebP files, preserving the alpha transparency that PNG users depend on. You get the format efficiency of WebP with the see-through backgrounds that logos, icons and interface graphics need.
Lossless-style PNG files are notorious for their size, and WebP routinely halves it while supporting the same alpha channel. For photographic content converted from PNG, even bigger savings are possible with lossy WebP at high quality settings — the tool exposes the dial so you can choose per image.
Conversion happens locally in your browser with no uploads and no watermarks, and batches of up to ten files are handled in one pass. Drop the results straight into a website or app and enjoy the immediate loading-speed difference.
Like every Piclizer tool, this one runs entirely in your browser — your files stay on your device.
