How Fast and Light Is OxnaPDF?
OxnaPDF is built to open quickly and stay out of your way. We measured it on an ordinary laptop against Adobe Acrobat, the PDF app most people know.
Measured on One Mac
Both apps were measured one after the other, alternately, on the same Mac at the same time: Apple M3 Max, 36 GB, macOS 26.7, on 6 Nov 2026. Each figure is the median of 5 runs after a warm-up.

How we measured:
- "Window open" is the time from opening the file until the app's window is on screen.
- "Busy until quiet" is the time until the app stops using the processor.
- Memory is the figure Activity Monitor shows, counting only the processes inside each app's folder.
- Other work was running on the Mac during the test, the same for both apps.
Why It Is Light
- One app on every platform, with our own PDF engine.
- No background services, updaters or helper processes left running after you quit.
- The online tools run in your browser, so they need no installation at all.
