About OnlinePCTools
We Build Tools That Respect Your Privacy
OnlinePCTools provides free, privacy-first utilities and file viewers so you can work with PDFs, images, audio, spreadsheets, and more — without uploading your data or signing up.
Our Story
Our Story
We started OnlinePCTools to solve a simple problem: most online tools upload your files to their servers. That means your documents, images, and sensitive data are sent over the internet and stored elsewhere — often without clear guarantees about privacy or retention.
We're developers who care about privacy and security. We built this suite so you can merge PDFs, convert images, view email files, and more without ever sending your data to us. Every tool processes entirely on your device using advanced technology.
There is no server-side processing, no data collection, and no tracking. Your files stay on your device from start to finish.
Why We Do It
