    Merge PDF Files

    It is a Windows library that merges standard PDFs into a final PDF

    The library is intended for developers, for inclusion in desktop applications or server services. There are lots of SDKs on the market creating (merging) PDFs (almost all of them have limitations). Our Windows library (MergePDFByNMI.dll) only merges standard PDF files (there are several PDF formats). You can send the input PDFs (by file name or by byte array) and you can have the final PDF (saved on a file or get back on a byte array). The library calls can be synchronous or asynchronous. We want to give you a benchmark, the library was used to create a PDF from single page(scanned) image by an OCR SDK (it is not included in our library, you can use any on the market): 20,000 Images (the OCR SDK creates single page PDF text searchable, running 50 threads) in 80 minutes. The size of the final PDF searchable was 800Mb. If you download the library, we provide a sample which cover all the scenarios possible (synchronous and asynchronous).

Guide to Open Source PDF Merge Tools

Open source PDF merge tools are specialized applications that can combine two or more Portable Document Format (PDF) documents into a single file without the need for proprietary software. Open source software is developed collaboratively by volunteer developers and is generally released with a license that allows users to freely use, modify, and distribute copies of the application.

The most common open source PDF merging tools rely on command line utilities such as pdftk to create merged documents from multiple PDFs. While command-line options provide powerful features, they may be intimidating for some users. Therefore, many open source projects have developed graphical user interfaces for manipulating the various functionalities offered by pdftk and other utilities like it. These programs offer intuitive navigation with drag-and-drop capabilities making it easy to organize files prior to merging them into one document.

Other than combining multiple PDfs, open source PDF merging tools also provide additional functionality such as watermarking softcopy documents and extracting specfic images from scanned documents. In addition these tools usually allow users to encrypt their content with passwords or digital signatures in order to protect confidential information stored in the files. Moreover depending on the tool used; text searchability can be increased by running an optical character recognition (OCR) engine over the converted documents which converts them from images into searchable text.

Open Source PDF merge tools vary greatly in terms of features and ease of use but nearly all offer basic manipulation capability no matter what their level of complexity may be; allowing almost anyone regardless of experience level to utilize this powerful technology without expensive licensing costs incurred when using proprietary applications like Adobe Acrobat Pro DC or NitroPDF Professional.

Open Source PDF Merge Tools Features

  • File Formatting: Most open source merge tools provide formatting options such as adjusting document margins, setting font type and size, selecting background color and layout orientation (portrait or landscape). These features help create professional-looking documents that are well-formatted for maximum readability.
  • Adding Page Numbers: Many open source tools offer page numbering settings which enable users to add automatic page numbers in the footers of their merged document. This is a great way to ensure accuracy when referencing specific pages within long reports or presentations.
  • Toolbars and Menus: Most open source merge tools provide intuitive toolbars with various features such as bookmarks, hyperlinks and watermarks which help enhance professional documents even further. A number of these programs also have customizable menus with additional settings and options that can be adjusted according to user preferences.

  • Apache Open Office Draw: Apache Open Office is another open source office suite, which includes its own PDF merging utility known as Draw. As with LibreOffice Draw, this tool enables users to select several different input files before generating a merged version of these inputs in one handy output file.
