Could you help test one browser-based image workflow?

I'm building MODO Studio, a free image tool that runs in the browser. Before I share it more widely, I'm looking for a few US-based adults to try one five-minute task: compress a JPG below 100 KB, convert a non-sensitive HEIC photo to JPG, or watermark two images and download the ZIP. I have original sample images for compression and watermarking. No account is needed, and you don't need to send me any files.

If you try one task, I'd value three details: which browser you used, whether the downloaded result opened correctly, and where the steps or error message were confusing. HEIC compatibility can vary by file and browser.

Which of these tasks comes up in your work, and what usually makes it frustrating? The tool is here: https://modo-studio.pages.dev/en/
