I built QuickTiny — 13 free browser tools, looking for honest feedback

Hey all — I built QuickTiny, a small collection of 13 free browser tools (image compressor, JSON formatter, word counter, password generator, and a few others). Everything free runs entirely client-side in the browser — nothing gets uploaded, no signup required for any of it.

There's one paid feature, a Batch Image Compressor, for $4.99 one-time (no subscription) — for people who need to compress a bunch of images at once instead of one at a time.

Right now my goal is just to get the first real users and, honestly, the first sale. No traction to report yet, which is exactly why I'm posting here instead of somewhere hype-driven.

Would genuinely appreciate feedback on:

1. Which tool is actually useful to you?

2. What simple tool should I add next?

3. Does the $4.99 Pro offer make sense, or does it feel off?
