No subscription, no ads, no daily caps. Buy credits, use them whenever — they never expire. And every conversion shows you its fidelity grade before you spend one.
Every route on cool_converter carries a fidelity grade, shown before you spend a credit — not buried in a results page after the fact. This is the one thing no other consumer converter does.
Deny-by-default routing: a conversion is only offered if it actually works, not advertised and hoped for. Every one of the 1,528 deliverable routes has a real, tested engine behind it.
No tier to pick, no monthly minimum. A simple document conversion costs 1-2 credits; pricing scales with the actual work a conversion takes, not a flat per-file tax.
Pay once, use whenever. Credits never expire — no downside to buying ahead.
Price a conversion before you sign in or upload anything. It's public information.
The product is the product. No "unlock more" behind a wall.
A conversion that fails because of us gets refunded automatically — not a support ticket.
