Running everything locally in the browser is a strong privacy angle. How does the image compressor hit an exact target size like 100KB - iterative quality steps, or resizing as well?

The local JSON formatter and the M3U8 player sit next to tip and mortgage calculators, which is an unusual mix. Are the dev utilities a separate app behind the same homepage, or one codebase? Also, does the QR scanner use the device camera entirely client-side so the image never leaves the browser?

Keeping the image compressor and JSON formatter entirely in the browser is the right call if people are resizing files they do not want uploaded. Hitting an exact target size like 100KB is the feature I would actually use before a form upload. Does that path only lower JPEG quality, or does it also resize dimensions when quality alone cannot reach the target?

Love that everything runs in the browser, so no files get uploaded anywhere. That's a big plus for privacy. Congrats on the launch!

Cool stuff. Maybe have this as a native software, user can just open the software and use these tools from there. Having this opened on browser will get lost in dozens of tabs.

Tried the decimal to fraction converter with 0.3333333. The exact fraction is right (3333333/10000000), but in Math mode the nearest practical fraction comes out as 5/16, error 0.0208, because the denominators are powers of two like a ruler. For Math mode a best rational approximation (continued fractions, capped at the max denominator) would give 1/3 with an error of about 0.00000003, and the inch and woodworking modes could keep the ruler steps. Accepting 0.(3) for exact repeats is a nice touch.

30 tools in one clean interface beats bookmarking ten different converter sites - the no-signup approach is what makes it sticky. Are you planning to add batch file conversion, or keeping each tool single-purpose to stay fast?

Keeping the JSON formatter and Markdown viewer fully in the browser is a good call for anyone pasting sensitive data. A small suggestion: a shareable link that preserves the input settings, like the QR code options, would make the tools easier to reuse. Do you plan to add a diff checker next?

The mortgage calculator is the one I would check first. Principal and interest alone understate the real monthly cost, so adding property tax, insurance and an optional extra-payment field, with an amortization table you can copy as CSV, would make it more useful than most single-purpose calculators. Does it already break out those pieces?

Running everything in the browser is a strong privacy advantage. With 30 tools, a search box and grouped categories on the tools page would help visitors find the right calculator or converter faster, and a small recently used section would make repeat visits quicker.
