PNG to WebP, without the upload step
WebP supports transparency and can make many web graphics smaller than PNG. The quality setting controls lossy encoding; compare fine edges and transparent boundaries before choosing a result.
Some image editors and publishing workflows still prefer PNG. Keep the source if you need lossless editing or need to support a system that does not accept WebP.
This png to webp workflow creates a separate processed copy in your browser. The image is not uploaded to an ImageKit server, and the original file is not changed. Choose a source your browser can decode, check the preview and measured file size, and save the result only when it fits your destination's requirements.
Files are decoded and processed on your device. They are not uploaded to an ImageKit server, and the original files are never overwritten.

Frequently asked questions
Does WebP keep PNG transparency?
Yes. The browser canvas preserves alpha when encoding to WebP, so transparent source areas can remain transparent.
Are my images uploaded?
Your image stays in this browser tab. Processing runs locally on your device; the image file is not sent to an ImageKit server.
Does this overwrite my original?
No. Processing creates a separate browser-generated file for download.
