A few months ago I was building a side project and needed to quickly
merge a pdf. Googled it, clicked the first result, and got hit
with a "create an account to continue" popup.
For a pdf merger. Free on the internet since the 90s.
So I built Mizakii.
It started as like 5 tools I kept needing. Then 10. Then I just kept
going and now it's 70+. Every single one is free, no account, no
watermarks, no upsells. Your data never leaves your browser.
Some tools I use myself constantly:
Hash Generator — MD5, SHA-256, SHA-512, bcrypt, NTLM
Password Generator — cryptographically secure, works offline
JSON Formatter — format, validate, minify
Cron Expression Generator — I always forget cron syntax
Regex Tester — live match highlighting
Gradient Generator — CSS gradients with copy-paste code
Lorem Ipsum Generator — by word, sentence, or character count
Base64 Encoder/Decoder — strings, images, file data
And 60+ more.
If you've ever Googled "free online [tool]" and been annoyed by what
you found,[] this is for you.
