Show HN: WebPtoPNG – I built a WebP to PNG tool, everything runs in the browser

I built WebPtoPNG after getting frustrated with converters that throttle uploads or phone data; everything runs straight in the browser, and never asks for a signup.

Why would you want to do it in a browser anyway? Just run it local. There are many open source image editors and converters to choose from.

ImageMagick is one: https://imagemagick.org/

GIMP is another: https://www.gimp.org/

Krita is another: https://krita.org/en/

Some ideas for improvements:

- Can you support more formats besides Webp and PNG?

- Too much text on the interface - This reads more like a landing page for a startup than a SPA tool. Compare to e.g. [0]

FWIW, you can do this with a few lines of JS in the browser using canvas.drawImage() from an img element followed by canvas.toBlob().
