How to Merge PDF Files
pdfFiller offers you a quick and easy way to combine PDF documents into a single file without having to install any software. The PDF merger helps you keep your records organized and consistent, so you don’t have to spend time trying to find all project-related documents. Whether you’re using a desktop computer or working on the go, you can use our smart PDF combiner from any device.
Below is a step-by-step guide that will help you easily combine PDFs into one document.
First, upload or create multiple PDF documents that you intend to merge. Then, select files to be combined, click the More button in the top panel, and select Merge.
Before you click the Merge button, set the document order before you merge PDF files. To do so, simply drag and drop documents in your preferred order. Once finished, enter a name for the newly merged document.
pdfFiller’s PDF joiner also allows you to rearrange pages inside the documents that you’re merging. Click the Advanced settings button in the pop-up window and select the pages that you’d like to be included in the newly merged document. After that, click Merge now.
Once your documents have been combined into a single file, you can download or save them in the cloud of your choice. You can also find your newly combined document on the My Documents page.
Other than the PDF compiler, pdfFiller has a powerful online editor that lets you type and delete text anywhere on a PDF, add sticky notes, watermarks, and logos, highlight, blackout, and draw shapes. Modified documents can be shared with others for signing and completion.
