Many PDFs in. One file out, in the order you want.
Private: your PDF never leaves your device.
No fixed number of files. Each file can be up to 100 MB, and very large totals depend on your device's memory.
No. Pages are copied as they are, so text stays sharp and selectable.
Files protected with a password cannot be opened by this tool. Remove the password in the program that made the file, save a copy, and try again.
Your PDF is processed in your browser. It is not uploaded, so it stays private.
We build business websites in 7 days and web apps in weeks, for a fixed price. Then we automate the busywork around them.
Book a free strategy callTo merge PDF files, add two or more PDFs, put them in the order you want and press Merge. You get one PDF with every page, at the same quality. It is free, there is no file limit, and the files are combined in your browser instead of on a server.
Most tools here run inside your browser. The file is opened on your own device and the result is made there too, so it is never uploaded to our servers. That makes them safe for contracts, IDs, payslips and client files, and they keep working on slow connections because nothing large is sent. You also do not need to install software or create an account. Every tool saves a new copy, so your original file stays exactly as it was.
