About Ori Tools
Ori Tools collects small utilities people reach for every day: cropping and compressing photos, merging PDFs, cleaning up text, converting units and picking names at random. Each tool opens in a second and works on phones as well as computers.
Everything runs inside your browser. Photos, PDFs and text are never uploaded, which makes the tools safe for documents and personal pictures. Some tools, such as the Korean tax and housing calculators, follow Korean rules and are labeled with Korea in their names.
