Hi Product Hunt! 👋
I'm Ashik — engineer from Bangladesh, builder by night.
I built ConvertKoro because I was frustrated with PDF tools that
upload your private documents to unknown servers. I wanted something
I could actually trust with sensitive files.
Everything runs in the browser. Your files never leave your device —
not even for a millisecond. 9 tools, all free, no account needed.
Two things I'd love from you:
1. Try one tool and tell me if it worked
2. What tool should I add next?
I'll be here all day. Ask me anything 🙏
