Congratulations on building this! I certainly do agree with the fact that there are a lot of sites that force you to upload, ask for your email, and sometimes even add a watermark to the image; amongst other unknown things.

Although from first look, I can tell you that there's a lot of text on the site and it's a bit too cramped. From my perspective, tools like these should get out of the way and the UX should be self-explanatory for an image "conversion" tool. Basically, just a box to select, drag/drop images, a few user inputs such as the output quality and format. That's about it. A single line at the top explaining what the tool does (and that it is local) should be good enough.

Also, the title says "PNG to JPG converter," but the rest of the site claims it can convert to quite a lot more than just those format. You can possibly change that to, as an example, something like: "ImageConverter - Convert images between formats, locally". And you can get rid of multiple pages, turning it into a single-page with all the possible output options.

As a sidenote, I've been using Mazanoke for this: https://github.com/civilblur/mazanoke. It's not my project, just something I happened to stumble upon a while ago, but it's similar to your project and works exactly like you would want it to.

From my test, the rest of it works great. Good luck!

Hey, thanks a lot for the thoughtful feedback — really appreciate you taking the time to write this

Totally agree with you on the UX point. I also believe these tools should be almost invisible — just drag, drop, adjust a few settings, and done. I initially added more text to make the privacy aspect clear (since many users don’t realize it’s 100% local), but you’re right — that could be simplified and better communicated with a single line. I’m already working on a cleaner layout with fewer distractions and a clearer “drop zone.”

Good catch on the title too! I started with “PNG to JPG converter” for SEO reasons, but as the app expanded to support multiple formats (WebP, PNG, JPG.), that label became outdated. I really like your suggested phrasing — something like “ImageConverter — Convert images between formats, locally” is a lot clearer and more accurate.

And thanks for sharing Mazanoke — hadn’t seen that before! Love that it follows the same “everything local” approach. I’ll take a closer look; maybe I can learn a few UX tricks from it as well.

Appreciate your kind words and testing it out! If you have any other UX ideas or thoughts on layout simplification, I’d love to hear them
