Top 5 software options to merge PDFs easily


PDF Merge

PDFmerge - free PDF combine

PDFmerge is a powerful online tool that can also be used offline if downloaded, that can help you easily combine two or more PDF files.

The user interface of both the website and the downloadable application are very user-friendly and are designed to make every option easy and comprehensive.

One of the downsides of using PDFmerge is that it has a limit of 15MB size files. In case you have a large number of PDF files to merge, you would have to take the files one by one.

This can cause efficiency issues when working with a large number of files. If you find yourself in this situation, it is recommended that you use other software options from this list.

The process of merging two PDF files is easier than ever. Just choose the files you want to merge by clicking the ‘choose file’ buttons, and then you can simply click ‘Merge’.

You can also process batch PDF files by using PDFmerge. In order to do this, you will need to select the multiple files you want to process and then click on ‘more files’ to be able to combine 5 or more files into one document.

Depending on the size of your documents, the process should take less than 30 seconds. After the processing is complete you can download your newly merged file on your PC or any other device.

The process of uploading your files to the PDFmerge servers is done by using a secure transfer with encryption connection, so you don’t need to worry about any third party having access to the data inside. More than that, all uploaded and processed documents and deleted after a maximum of 24 hrs from the last login session.
