hello,

as always: imho (!)

congratulations on shipping!!

fwiw: i have to admit, i may be getting "to old" to understand this online/service hype which took over "the it world" years ago ...

create an online-service and market it with "no upload", "local", "privacy" etc...

idk ... whats the advantage over "my" image-conversion-tool which i use heavily since decades ... if i remember it correctly, since around the late 1990ties (!) ... drummroll ... meet:

ImageMagick ~ Mastering Digital Image Alchemy

* https://imagemagick.org/

its utility called "convert" does everything a "normal" person could want for image-conversion.

its FOSS, runs locally in your terminal or GUI, produces stunning results and again: no internet needed, no privacy-concerns etc...

source-code available at

* https://github.com/ImageMagick/ImageMagick

it has lots of language-integrations etc.etc.

* https://imagemagick.org/script/develop.php

just my 0.02€

ps. if i want do develop such a converter which could run locally in the browser, i would take a look at the wasm-port of imagemagick, available here:

* https://github.com/KnicKnic/WASM-ImageMagick

I think a quick tool online is more convinient for common use cases, without install software. when-ever, where-ever a browser is ok.

however, for professional requirements and use cases, a professional software is a MUST choice.

different requirements, different service to met :)
