Assemble PDFs Together

When dealing with numerous forms, sometimes it’s necessary to combine and send them together as a single email attachment. Forms may be various samples or blanks, and you may need to provide additional documents. A user can also arrange images and text files and combine them into a single PDF document. Our website allows you to process your own templates faster with the help of a special function. Assemble PDFs online using your Mac and start saving time and money on printing! This online service is easy to use and requires no searching or downloading of additional software.

How to Assemble Different PDF Files

To combine several files into one, follow the steps below:

Multiple source files can be uploaded to your account on our website. Open the “My Box” tab in the menu if they are already in the docs list.

Next click on “More” and you will see the drop-down menu with additional tools. Then click the “Merge” button.

You will see a new window with the list of the documents to assemble. If their order is correct, then move to the next step of this user guide. If you want to change the order of items, remove them and arrange them in the necessary way. Give a name to the final version that will include all PDF documents. Click on the “Merge” button. The system will combine all the blanks into one. It will be saved in the same folder as the originals. Before you assemble the PDF files, arrange all of them to be in the same folder. Now your template is ready and can be further edited, sent or shared. Additionally, you can print it or send it to someone for signature. If you are worried about the security of the given information, use the file locking feature or require an additional verification check when it is opened.

Stupid-Easy to use Very easy to get used to. This should be called PDF-Text for Dummies. I literally had this program up and running in less than 5 minutes of downloading and installing it. Wish it was a little cheaper. If you are not using it often it hard to justify the monthly cost. It may be better to go with the annual subscription instead of the monthly in some cases.

Completed what I needed done Completed what I needed done. The reason for 4 stars is because you force people to sign up for a monthly subscription versus just charging for the one time use of the feature.
