The quickest and the nicest tool for arranging PDF documents online. Simple and useful. I use AltoMerge on my Mac and my Android smartphone and it works well on both devices.

I’ve been using AltoMerge to combine large PDF files for a long time now. I do think it’s the best free solution on the web. Oh, and there’s also an option that enables you to redact the merged PDF file. Awesome!

Previously, merging PDFs was an issue. I’ve tried a number of apps and platforms but none of them seemed to work well enough. Now, I use AltoMerge on a regular basis and have everything I need in one place. Great app!

What I love the most about this app is that I can use it on every device. With AltoPDF, I’m able to process PDFs both at work and at home - regardless of what device I’m using. Nice work!

Way to go, AltoMerge! I use your app whenever I need to glue two or more PDFs together. It’s simply amazing how fast and simple the app is. All the necessary instruments are available for free.

Despite its simple user-friendly interface, AltoMerge is a powerful and convenient tool which can not only be used as a PDF merger but an editor as well.

I love working with AltoMerge. It saves me a lot of time every day. I was using paid apps before or process my PDFs via Microsoft Word. Now I have everything I need absolutely for free

I use AltoMerge to combine and share PDF documents. It only takes a few clicks and less than a minute to process almost any PDF on my PC and email the resulting file to my colleague.
