Part 1. How to Correct Textual Errors in a PDF

Do you have a PDF document that contains a serious error in it? Or do you have a PDF file that you need to edit by removing some pages that are superfluous or making other types of corrections? What you need is a tool PDF Editor, that is a program that can open the PDF and allow you to modify it in the simplest and most intuitive way possible.

We have already covered various ways to edit text in a PDF file, and we can divide PDFs into two types: software e online services. The first type consists in downloading and installing on your computer (Windows or Mac) a program that is able to manage, change and correct text (or images) present in the file. The second type consists in using online services, on which you must first import the PDF and then you can edit it. Below we report these two solutions, one for each type.



A) Correct PDF Text with PDFelement Software

If you want to correct a PDF from every point of view you need a professional software solution like PDFelement. It is a program that has established itself over the years as one of the best alternatives to Adobe Acrobat (and certainly cheaper!). To use PDFelement to correct errors in your PDF here are the simple steps to follow:

Download the free trial version software for Windows or Mac from below:

 

Install and start PDFelement. You will see this splash screen:

Click Open File to select the PDF document to be corrected from your computer. Once selected it will preview in the program. At this point click on the menu at the top "Modification”And then select the part of the document (eg text or text blocks) to modify and correct.

You will have all the text formatting tools you find in Word and other Office software. So the use of the software is really simple and intuitive, and within everyone's reach.

The great advantage of using this type of programs to correct PDF is that you can also import scanned PDFs: the PDFelement software thanks to the function OCR will be able to make the document editable in all its parts and you can then save it again in PDF format.

To make corrections to the PDF it is also possible to access the section ANNOTATION and here use the many tools made available. You will be able to correct a PDF as if it were a paper sheet and apply notes in red, highlight incorrect text, insert boxes or arrows, and much more.


Once the corrections to the document have been completed, you can save the file by clicking on the menu File -> Save As. With the free demo version of the program the PDF will be saved on your computer but there will be an overlay watermark. It is essential to purchase the license to remove this limitation. Below is a short video tutorial showing how you can use PDFelement to correct and edit a PDF:


B) Correct PDF online

If you don't want to install any programs, a good service to edit PDF online is PDFZorro. To use this service, access this page and upload the PDF you want to correct and / or modify. To upload a PDF click on the button Upload, or you can import it directly from Google Drive.

After selecting and importing the PDF click on Start PDF Editor and the screen will open where you can select the page of the PDF to edit and use the various tools available. For example, if there is some text you want to erase you can use the Erase tool, a kind of eraser that allows you to remove incorrect or unwanted text.

After making the changes and corrections you can save the corrected PDF by clicking on the button at the top left Finish/Download. That's all!

It must be said that PDFZorro does not have all the PDF editing functions that are present on software solutions such as PDFelement, but it is a service free which allows you to make small corrections such as deleting and adding new text, highlighting sentences and rearranging the document pages.


 

Part 2. How to Fix / Repair a Corrupt PDF

If you find yourself in this article because you want to correct, or better repair a damaged PDF, what you need is a tool that can analyze the file and repair it. Unfortunately, the repair of damaged PDFs is not always guaranteed, so we recommend that you use the Free demo of a program called PDF Repair to first see if it's still recoverable. Here are the detailed steps to follow to do this.


Step 1. Download, install and launch PDF Repair

Click on the button below to access the page where you can download the free demo version of the PDF Repair program:

After downloading and installing the program, the following main window will open:

Step 2. Import PDF document to repair / fix

Click on the button at the top left SELECT FILES to import the damaged PDF

Step 3. Start the PDF repair

Click on the bottom right REPAIR to start repairing the selected PDF. Wait patiently for the process to finish. Under the "Progress Indicator" column you will see "Done" as soon as the repair is complete.

Compared to other similar software, this utility has some advanced features. In fact, the software has been programmed so as to be able to identify the PDF structure in almost any condition and then restore it. The positive aspect of the software is its ability to determine the source location of the text data and to perform the necessary actions to repair the PDF file in a short amount of time.

Don't forget the fact that during the recovery process, this software performs a full scan. The software is well integrated with the data recovery algorithm (QFSCI), which plays a decisive role in scanning damaged PDF files. The tool evaluates the damaged or corrupted PDF file and then corrects it. This method is followed by the rebuilding the file with the data of the recovered PDF file. The scan time depends on the level of corruption and the size of the file. If the process is running, it indicates that the application is still analyzing the damaged file. You just have to be patient because at the end of the scanning process you will get the repaired file.
