About OpenTools Pro
We make free online tools that respect your privacy and just work.
Our Mission
We believe essential online tools should be free, fast, and private. OpenTools Pro provides 7 powerful utilities that process everything in your browser — your data never touches our servers. No accounts, no watermarks, no compromises.
Privacy by Design
Your files and data stay on your device. Our tools run entirely in your browser — images you compress, PDFs you merge, and text you analyze never leave your computer. We can't see your data because we never receive it.
How We Make Money
We're transparent about our business model: OpenTools Pro is supported by display advertising via Google AdSense. This lets us keep every tool completely free without compromising your experience. We don't sell your data, and we never will.
Our Tools
From image compression to mortgage calculations, each of our 7 tools is built to solve a real problem as simply as possible. We focus on speed, accuracy, and ease of use across every device.
