No Advertising When You Merge PDF Documents

In the past, you might have found software that promised to combine PDFs but, once you downloaded the resulting file, there was a watermark on every page. By comparison, rest assured that our merger tool is developed to merge files without adding a watermark or any other advertising.

Joining PDFs Has Never Been Easier

Forget about the complex processes to combine PDFs that you may have encountered in the past. As this is a 100% online PDF combiner, the only thing you need is your internet browser. The merging process takes just a few seconds, resulting in a single convenient document to download, easy-peasy.

Step By Step: How To Merge PDF Files

Here are the steps to merge your PDFs with our tool:

  1. To upload the documents you want to merge, select all of them (ctrl + click on Windows; cmd + click on Mac), and drag them to the action space above. If you prefer, you can also click on the "Select PDF files" button and upload the documents from the file explorer.
  2. Organize the files in your preferred order, and click on the "Merge PDF" button.
  3. In a few moments, your browser will automatically download the resulting file. If not, you can download it manually by clicking on the "Download PDF" button.

Other Options To Combine PDFs

Windows doesn’t offer any default programs for this action, but there are many installable software solutions to combine PDFs. Whatever program you use, the procedure is as follows:
  1. Open your chosen program to merge PDFs and load the first of the files.
  2. Now look for an option called "Merge", "Combine" or "Group" (the name changes depending on the program). Click the option, and select the other file you want to combine.
  3. Do this and, in a matter of seconds, your file will be ready.

Mac users have the advantage that macOS, Apple’s desktop operating system, has a native option to merge PDFs. This is done with Preview, Apple’s default PDF viewer. The steps to follow are:
  1. Open your file with Preview.
  2. Tap on "View" and then click on the "Thumbnails" option.
  3. Select the thumbnail of any page, then go to "File" > "Edit" > "Insert", and then select "Page". If this last option is turned off, it means that the document is protected against editing.
  4. Select the file you want to add and, finally, go to "File" and click on "Export as PDF" to save the merged file.

Android doesn’t have any in-built options to merge PDFs, although fortunately, there are apps available in the Google Play Store to do this. There are paid apps, such as the well-known Adobe Acrobat Reader, and there are free options. To find a free app, the best thing is to search by typing “combine PDF” or something similar.If you decide to use Adobe Acrobat Reader, which requires a paid license, the steps to combine PDFs are as follows:
  1. Open Acrobat Reader on your Android phone or tablet.
  2. Click on the "+" icon at the bottom right of your screen.
  3. Tap on the "Combine files" option and follow the on-screen instructions.

The steps to merge PDFs on iPhone may seem a bit confusing at first, as they differ from the procedures for other devices. However, fortunately, this action can be executed in a few minutes as follows:
  1. Go to the Apple App Store and download any of the available applications to merge PDFs. You can search for "merge pdf" to see the most popular options.
  2. Once you’ve installed the app, navigate to the Files app, the default app for viewing files on your iPhone.
  3. Here, select the files you want to merge, tap on the "Share" icon (with an arrow pointing up) you’ll see at the bottom of your screen, and then choose the merge PDF app you’ve installed.
  4. Now, follow the on-screen instructions.

Frequently Asked Questions About Joining PDFs

The more pages the file has, the more space the document will occupy. If you want, you can compress the resulting PDF so that it weighs less.However, the merged file shouldn’t take up twice as much space. This is because the files you join share a lot of information in the .pdf extension that doesn’t need to be duplicated.
