PDF or other document files usually contain important content that people use for school, work, businesses, and other professional-related activities. Hence, having them become corrupted causes stress and frustration, especially if you have spent hours or even days crafting such an important file. In this case, what would be the best thing to do? Well, the good news is that solutions are available to repair corrupted or damaged PDF files, and you can find the best ones below.

Part 2. The Adobe Acrobat Re-Saving Trick

You may also use the official Adobe Acrobat software to fix a PDF that's been corrupted. Instead of using repair tools, this approach relies on a simple re-saving process. The main idea is to open the damaged file in Adobe Acrobat and then save it again under a new name or in a different format. This forces the program to rebuild the file structure and fix minor corruption. However, this method works best for files with only slight damage.

Follow the procedure below to grasp how to fix corrupted PDF file using the Adobe Acrobat re-saving trick:

Step 1Open the PDF file that is corrupted using Adobe Acrobat. Even if the file shows an error, try to proceed and open it anyway.

Step 2Next, go to the File menu and choose Save As to re-save the PDF file with a new name or in a different location, then try reopening the newly saved copy.

Part 3. Bypass Corruption by Converting PDF to Word/Images

It is also possible to bypass PDF corruption by converting the file to Word or an image. Instead of trying to repair the damaged file directly, you can extract the PDF's content by converting it into a Word document or an image file format. Like repair tools, converters can also be found online, and you should only use a reliable one, such as the Adobe PDF Converter. Its website interface offers a simple and straightforward design, making the process easy for all users. You can then expect the output PDF to no longer be corrupted.

Follow the guidance below to determine how to open corrupted PDF file by bypassing corruption by converting the PDF to Word or images:

Step 1On the Adobe PDF Converter's website, click Select a file and pick your PDF to upload.

Step 2Once uploaded, choose Microsoft Word or image format from the options before choosing Convert to DOCX/JPG. Once converted, download the file.

Part 4. Restore from Previous Versions

If File History is enabled on your computer, repairing your PDF by restoring its previous version will also be effective. Although the file may be corrupted, its text and images are often still recoverable. This method relies on your system's built-in backup feature—you go back to an earlier, uncorrupted copy of the same file that was automatically saved by your computer. Instead of fixing the damaged file, you simply replace it with a working version from a past date. However, it only works if you have enabled File History beforehand.

Follow the task below to recover corrupted PDF by restoring from previous versions:

Step 1Right-click on the PDF that's corrupted and select Properties from the pop-up menu.

Step 2When a dialogue box appears, choose Previous Versions in the upper section to view the past versions of the file. From there, select and restore the uncorrupted version of the PDF.

Part 5. Try FoneLab Data Retriever
