Show HN: Pastehub.app – 100 % client-side toolbox for whatever you just copied

I kept opening 10+ tabs for the same daily clipboard chores, so I crammed a bunch of tiny client-side tools into one page:

Drop any image → OCR + dominant color palette + QR/barcode decode Paste “72 kg in pounds”, “50C to F”, “180 cm to feet” → instant conversion Paste any math expression → instant result JSON pretty/minify, JWT decode, Base64 → text/file, hex, URL tracking-strip, etc. All 100 % in-browser, zero backend, nothing ever leaves your machine

It’s deliberately over-engineered for the weird stuff I copy every day. Try throwing something at it and tell me what breaks or what’s missing.

Feedback button goes straight to me.
