When the file formats may vary, the page sizes of different files are also inconsistent. Once required to combine various documents into a single one, what should we do to ensure the files are uniform in size? This guide mainly focuses on how to adjust the sizes of different pages.

Here is a step-by-step guide:

Step 1: When the converter is activated, click PDF to Image, and then hit Start to save the images converted from the former PDF file into a specified location;
Step 2: Open the destination folder to view all the converted images. Go back to the SwifDoo Converter to select Image to PDF and then add the images to the operation console;
Step 3: Be sure to tick the direction of this new document under the Page Size tab to standardize the size and orientation;
Step 4：Click the Start button again to finalize the entire conversion process.
After this, open the newly created document and verify if it meets your needs.

In the past, if we wanted to save the document in the form of a scanned file, you needed to print the editable PDF file as a paper document and scan it into an electronic draft with a scanner - which isn’t environmentally friendly and rather troublesome.

SwifDoo PDF is a 10 MB software that doesn’t require too much disk space. Meanwhile, it integrates powerful and useful functions, making it a desirable office software. Following are the steps for creating scanned copies:

Launch SwifDoo PDF and click the “Advanced” button;

When the SwifDoo PDF Converter window pops up, select “Add Files” to upload the specified document to the operation console from the local folder;

Click the “Start” button after successfully uploading the file. When the conversion is completed, click the converted document to see if it meets the demands.

Given that scanners are too heavy to be portable and typing the document manually consumes too much time, you can try the “Convert to Scanned Copy” feature provided by SwifDoo PDF, and create a scanned copy of any file with the above mentioned three steps.

Now that paperless offices have been widely encouraged and accepted, many of us have to process piles of digital files daily. This may bring forth a specific scenario: sometimes when printing a document, half of the page is left unused, resulting in a waste of paper. There is a large blank area on the page simply because the content isn’t long enough and doesn’t completely cover the page.

Suppose multiple documents of the same type can be printed together (one or more pages). In that case, it is possible to waste less. Turn "if" into "reality" by following the steps below:

Step 1: Click the “Page” tab and select “Merge” to combine multiple PDF documents into one;

Step 2: Open the document by clicking “Open Documents” to check whether these files have been successfully combined into an individual document;

Step 3：Click the “SwifDoo” icon at the top left corner and then select “Print”;

Step 4: When the below window pops up, tick “Multiple” under the “Page Size and Handling” tab to realize printing multiple documents within a single one.

This method is straightforward and can save both time and energy, only requiring a few clicks!

Even in the context of a paperless office, printing out paper documents is often necessary. Sometimes though, only a portion of the document needs to be printed and not the whole thing. In this case, many users don't know how to proceed.

Are you wondering what to do if you only want to print the boxed-out portion of the document rather than the entire page? Take a look at the following to understand what should be done:

Now, let’s dive into printing only a selected area of a PDF document:

After selecting the printed area, click “Apply Changes” on the right dropdown menu;
Be sure to save the changes, and then click the “Print” icon (Ctrl + P) to print out the specified portion;
On the pop-up window, tick “Current Page” to finalize the entire Furthermore, you can access a preview of the printed document to check if it satisfies your needs.

Occasionally, the need to sort out and categorize many digital documents and materials at once arises and the entire process is very time-consuming. Documents belonging to the same type ought to be categorized and sorted together. If a certain document contains certain content that is more in line with another type of document, the page within the document needs to be substituted.
