2. OpenKM
OpenKM makes editing & merging PDF files very easy.
It has a dedicated PDF editor, which lets you rotate pages to sort out incorrect orientations caused by some document scanning equipment, and even insert new ones as well during document merging.
On top of that, OpenKM enables you to add annotations and watermarks to your new document in order to display ownership or protect sensitive content.

Verdict
OpenKM is an excellent option to consider if you’d like to improve PDF merging and version control in your workflow. That being said, the interface is quite clunky and so navigating between features and documents can be cumbersome and inefficient.
3. Soda PDF
Need a purpose-built tool just for PDF merging?
Soda PDF is an excellent small business document management software that’s specifically dedicated for merging PDF files, therefore removing unnecessary features to make the software extremely easy to use.
Additionally, it lets you merge and combine documents from more than 300 file formats into one seamless PDF, therefore increasing your business’s versatility.

Soda PDF supports over 300 different document file types, making it the best PDF merging software on account of versatility. However, I’ve noticed its free trial lets you merge only three PDFs, which may not be enough to figure out if it’s the right fit.
4. DocuWare
DocuWare offers temporary PDF merging features.
You can use the digital clip feature to bind multiformat documents into one PDF file. These files still exist individually, however, you can scroll them in one go rather than separately, helping to ensure effective file management and organization.
It also offers a digital stapler for scanned documents and PDFs, which enables you to permanently combine files to enable easy sharing or printing.
Just like FileCenter, it integrates with Outlook to let you import documents from email. So it can help you improve email document management and communication, by combining and storing email information into a strategic folder.

Verdict
If you have short-term merging needs, DocuWare is a great choice when you need to bind files temporarily just for quick reference. Nonetheless, I’ve noticed that it’s incompatible with many file formats so you may need to pair it with a PDF converter.
5. Revver
Need to add extra information to a file?
Revver is one of the best DocuWare alternatives in this regard, offering an append and prepend feature that lets you add files to the end or start of the document respectively.
Moreover, it lets you add fillable fields to forms allowing you to gather important data from recipients such as digital signatures, names and addresses.

Revver offers several automation features to help streamline merging and other repetitive document work for your business. That said, I’ve noticed that Revver’s mobile app has very limited PDF functionalities, and it’s a struggle to use it to merge PDF files.
6. NetDocuments
NetDocuments is a legal-oriented document management tool.
While it is a great solution for managing essential legal documents for your enterprise, it also offers reliable PDF merging features that let you combine several, separate Word and Excel files into one document that’s easy to share or archive.
NetDocuments also comes with PDF redaction tools so you can block sensitive information during merging to comply with regulations & preserve confidentiality.
Need to bolster PDF document security?

Verdict
NetDocuments is a great PDF merging solution if you’re looking to merge and manage legal documents more efficiently for your business. Nonetheless, I’ve realized it’s largely a cloud-based solution so you get no offline PDF merging and editing capabilities.
7. SmartVault
Do you have files in Google Drive you’d like to merge?
SmartVault is a cloud-based document management software and integrates with popular cloud services, enabling you to easily import and export files online.
It also offers PDF viewing for large files on both mobile and desktop, enabling you to open and combine PDF documents from within these platforms.
Just like FileCenter, you also get a client portal for secure file sharing, enabling you to share merged files conveniently and securely. You can even request for e-signatures through this portal to enable remote document signing.

Verdict
SmartVault’s dedicated client portal makes it a great option to consider if you’d like to merge and share PDFs more securely. However, the user interface is a bit outdated and has a complex layout, which makes it quite challenging to learn and use efficiently.
8. Smallpdf
Smallpdf offers powerful PDF merging & compression.
This enables you to combine even essential real estate documents like very bulky tenancy agreements for a particular property, for example, and compress them to improve space-efficiency and shareability as well.
Moreover, Smallpdf can display individual pages in uploaded files, enabling you to reorder and merge different pages into one document with related information.

Verdict
If you’re looking for the best PDF merging software for mobile, I recommend Smallpdf which improves your productivity on the go. That being said, you’ll need the pro version plan to access advanced & essential merging features, which can be really expensive.
9. PairSoft
Interested in merging monthly receipts into one file?
You can make it happen with a top accounting document management software such as PairSoft, which is an AP automation solution with reliable PDF merging features. These enable you to merge all types of documents to keep them neatly organized.
Crucially, PairSoft supports selective merging, whereby you can select individual pages to merge from different files rather than combining entire documents.
If you have a high volume of documents you need to put together, I recommend PairSoft for its bulk PDF merging feature. It improves business document management efficiency by allowing you to simultaneously perform two or more merging tasks.
Best features:
- Its dynamic AI-powered OCR document capture feature automatically extracts data fields from PDFs and emails so you can merge them easily later on.
- PairSoft lets you combine financial statements, receipts and invoices via a drag-and-drop functionality to enable easy financial reporting for your business.
- It can also compress large files, enabling you to optimize storage space or meet email size restrictions when sharing documents with clients and colleagues.
Pricing:

Verdict
PairSoft’s batch PDF processing makes it a top option to consider for streamlining a high-volume document workflow. Unfortunately, there are very limited PDF editing functionalities available and you may need to bridge these gaps with third-party tools.
10. PDFsam
PDFsam is an open source PDF merging solution.
It lets you combine several different PDF files into one document, helping improve your startup’s document management workflow and solving fragmented information issues.
What’s more, it lets you crop documents during merging to adjust the visible area in pages and capture only the information you need from particular sections.
Worried about unauthorized access to sensitive information?
PDFsam automatically deletes copies of documents you’ve uploaded to its servers within one hour, helping you protect private information for your small business and meet your data privacy and compliance requirements.
Best features:
- You get a simple drag-and-drop editor that enables you to easily and quickly upload files from your computer to PDFsam for merging operations.
- PDFsam’s ability to combine up to twenty PDFs at a time makes it a great solution when you’re dealing with a highly fragmented document workflow.
- It also gives you the option to reorder pages to match your desired sequence, and even compress these files to reduce the size of the output document.
Pricing:
- Unlimited free trial.
- Starting plan: $69/user per year.
Verdict
If you’re looking for an effective open-source software that gets the job done, PDFsam is an excellent option to consider. However, I’ve noticed it’s a very simplistic document merging tool and lacks essential features such as advanced formatting control.
