Can you review my online toolbox website?

I’d really like some blunt feedback on the UX + “what is this site even for” part. It’s basically an online toolbox of small utilities (networking stuff, text/data converters, encoders/decoders, lookup tools, etc). I’m trying to make it actually useful and easy to navigate, not just a random list of tools.

Questions (answer any subset, whatever you feel like):

In the first ~10 seconds, is it obvious what the site is for and who it’s for?

Does the homepage/categories feel too much / overwhelming? what would you simplify first?

How would you expect to find a tool on a site like this (search, tags, categories…)? what’s missing?

Trust/privacy wise: what would you need to see to feel comfortable using it (especially for paste/upload type tools)?

Anything that feels useless or duplicate that I should just remove/merge?

If you’d bookmark it: what 1–2 things would need to stand out?

Thanks in advance — genuinely appreciate any honest feedback.
