Why is OToolbox 100% free?
We were tired of visiting pages full of fake "Download" buttons, intrusive pop-ups, limits of "only 2 files a day" and the obligation to leave our email just to merge two PDFs or remove a background.
That's why we created OToolbox. We wanted a clean, ultra-fast and secure corner of the internet. There are no distant servers processing your confidential documents or private photos here. All the heavy lifting is done by the power of your own browser locally.
No tricks. No ads. Just tools that work.
