• Convert – to Word, Excel, PPT, or JPG.
• Split – the opposite of merging.
• Rotate – turn single or all pages.

Is Your Online Service Secure?

You know it! So much so that millions of people use Smallpdf every month to convert their documents. Merging PDF documents is one of our most popular tools. We adopt secure TLS connections for file transfers and delete them after 60 minutes of processing—just enough time for you to edit and download your documents.

Is Smallpdf Really Free?

Oh yes, a few times a day. The platform was created to solve common document-related problems. If you have many documents that need to be processed, you can “go Pro” for the price of a latte each month ($3/month).

If you reach the daily usage limit on our site but still have files to merge, try out Pro for free. We offer a 7-day free trial of Smallpdf Pro, which removes any limitations and gives you full access to all our tools, including the Smallpdf Desktop App (read on for more info).

How To Merge PDF Files With Adobe Reader Offline, for Free

While Adobe offers a great offline PDF reader, it requires a paid subscription for you to merge, annotate, convert, and edit your documents. However, we, too, have an app to help you get your document work offline. While it’s not free like the online version, it’s included in the aforementioned 7-day free trial. Here’s how to merge PDF files offline with the Smallpdf Desktop App:

1. Open the Smallpdf Desktop App.
2. Click “Merge” on the left-hand side.
3. Arrange file positions as you please.
4. Click on “Merge files,” and you’re done.
