Free, private tools that just work.
450+ browser-based utilities for developers, designers, marketers, students, and everyday internet users — no signup, no uploads, no tracking.
Our Story
Toolzer was born in 2024 from a simple frustration: every time you needed a quick online tool — compress a PDF, check your IP, generate a QR code — you had to wade through ad-heavy sites that uploaded your files to unknown servers. We decided to build something better.
Toolzer is a free, privacy-first toolkit that runs entirely in your browser. No accounts. No uploads. No tracking. Just tools that work.
Today, Toolzer offers 450+ free tools used by developers, designers, marketers, students, and everyday internet users in over 150 countries.
