How it works
Add two or more PDFs, arrange them in the order you want, and tap Merge. The merging happens entirely in your browser using WebAssembly-era tech — no upload, no queue, no watermark, no sign-up.
Why merge before printing?
One combined document prints in the exact order you arranged, with nothing missed — much safer than sending many small files. If you're ordering printouts from us, merged files are also cheaper to handle and ship.
