I'm Mário, an architect in Porto. I needed to merge and split PDFs every week, and I didn't like sending contracts and client drawings to servers I knew nothing about. So I built tools that do the job on your own device.
Your file travels to their server and back. A copy exists on someone else's computer, at least for a while.
The tool comes to your file, not the other way round. It runs in your browser and never sends the file anywhere.
That's also why it works with airplane mode on. Try it.
Every tool, no trial, no premium plan.
No account, no email, nothing to remember.
Your pages come out exactly as they went in.
Once the page has loaded. Make searchable needs its language file the first time.
I read every message. It's one person, so replies can take a few days.
