Majority of us occasional bump into PDF files. Ideally, one would require Adobe Acrobat software installed on the computer to work with PDF files. However, if installing additional software on computer is not your cup of tea (like many of us) try online alternatives. MergePDF.net is a cool option to merge multiple PDF files without installing any software on the computer.
There is no need for registeration or sign-up, just select PDF files from your computer and hit the Merge PDF button. It does have few limitation which wont affect majority of users. You can upload maximum of 10 files with individual file size limit is 5 MB. Also, more files you upload more time it will take to merge – checkout MergePDF or download offline free alternative PDF Split & Merge. [via]
