PDF is one of our most commonly used formats, but when faced with dozens or even hundreds of PDF scanning contracts, reports, financial statements or scattered resumes scattered in folders, how to batch merge these documents into a complete document for easy browsing has become a biggest problem. Generally speaking, we can only find a PDF editor to manually insert PDF one by one, and several files are acceptable. If there are too many documents, the efficiency is not only low, but also error-prone, especially if you need to process files regularly every day or every week, this kind of repetitive work will consume a lot of time.
Here, I 'd like to introduce several practical methods to easily batch merge scattered PDF files in multiple folders, so as to make the sorting of files simple and efficient. Let's try it with me!
When do you want to batch merge all PDF files within a folder?
Too many files
during work and study, we often encounter the situation that there are many PDF files in a folder. It is very troublesome to open and view them one by one, and we will miss the content. If we need to read them as a whole or continuously, we will find that the experience is very poor. At this time, all PDF files in the folder will be merged into one file to gather all the contents together and view them more smoothly.
Submit complete documentation
only one complete document can be submitted for data submission and online review. If there are many scattered PDFs at the beginning, they must be merged first, otherwise the requirements cannot be met. The same is true when printing. Separate printing of multiple PDFs is easy to be out of order and requires repeated operations. However, a complete document can be generated at one time by batch merging all PDFs.
Easy archive management
scattered PDF files are easy to miss or disordered when saving and storing, and it is not convenient to find them over time. However, after merging PDF files in the same folder in batches, only one file is kept, which not only makes the space clearer, but also facilitates unified naming and filing. This method is simple and intuitive, can greatly reduce the trouble of file management and improve the overall work efficiency.
