Converting a PNG to JPG to save space means giving up transparency entirely, since JPG doesn't support an alpha channel at all, but WebP was built to compress noticeably smaller than PNG while keeping that same transparent background intact, so a logo or an icon with a see-through edge doesn't have to choose between file size and staying transparent. This tool converts PNG images into WebP, keeping alpha transparency intact while cutting file size, in a format nearly every modern browser now renders natively.

Useful for shrinking a transparent PNG icon for a faster-loading web page without losing its see-through background, converting a batch of PNG screenshots to a smaller format for a site that already supports WebP, or reducing image weight on a page without switching to a format that would flatten transparency to a solid color.

Quick answers for PNG to WebP Converter

How much smaller does WebP actually end up compared to my PNG?
It varies by image, the After panel shows the converted file size next to a note like "42% smaller" or "smaller/larger", calculated directly by comparing the two file sizes after conversion.
Is transparency preserved when converting to WebP?
Yes, unlike a JPEG conversion, WebP supports an alpha channel, so transparent areas in your source PNG stay transparent in the converted file.
Can I fine-tune the compression instead of using a fixed setting?
Yes, a 1 to 100 quality slider controls the WebP encoding, and you can re-run the conversion at a different quality and compare the resulting file size before deciding which to download.
