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

#1
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.

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]

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/

People don't want to install/download/vet reputation of local apps for spontaneous, one-off tasks.

Also, the aesthetic design is too "professional" and therefore not trustworthy.

A trustworthy utility page should look like a CSS-less crappy HTML form.

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().

Firefox now adds random noise to all canvas readback operations (getImageData, toDataURL, and toBlob).

Although I can't speak for everyone, my browser runs locally.
