A Reddit user recently complained about a frustrating situation: "I was drawing a picture in MS Paint, but after restarting my PC, I couldn't open the file. MS Paint says the file isn't a bitmap and isn't supported. Windows Photo Viewer also won't open it, saying the format isn't supported. I've tried various programs and a photo repair tool, but nothing works. It's a PNG file, so I think it might be corrupted."
This regular situation demonstrates a frequent digital nightmare: losing access to your files due to corruption. Fortunately, there are internet solutions developed to address this specific issue. This article will look at four must-have online PNG file repair programs to help you recover your valuable files quickly and efficiently.

Part 1: Understanding PNG Corruption
Do you remember a time when you attempted to open an image file and received an incorrect rendering? If it is PNG format then there maybe problem in that file. Let's find out the concept of corruption in PNG, why it occurs, and how it impacts your files.
PNGs, or Portable Network Graphics, are one of the most commonplace picture formats. Consumers opt for PNGs because they enable transparent backgrounds and do not compress quality during their storage. It is suitable for the web interface, such as logos or icons.
The following are some common sources of corruption in PNG files:
- PNG files can be very delicate, and if your computer shuts off during the process of saving the file it will be over. This can happen after a power surge is experienced or after the computer system has locked up.
- Viruses are nefarious programs that can infect files, including PNG images. Frequently scanning with an antivirus software can also help safeguard your files.
- Often, a PNG file you want to view or edit has been altered by a bug in the software you are using.
- In case there are issues with your hard drive or USB stick, files including but not limited to PNGs may get corrupted.
Sometimes the PNG files may get corrupted and this may lead to many problems that may concern the way images are to be viewed or accessed. The most obvious problem that may arise is that the file is not opening, and as a result, you cannot see your photograph.
Often the message appears that the software does not recognize the file type meaning your program does not see the file. However, if the file is opened, then the quality of the displayed image could be compromised. Some areas of the image may be missing or have incorrect color shades depending on the changes made.
Moreover, your picture viewing or editing software behaves strangely because corrupted PNG files introduce havoc which makes it freeze or crash suddenly. These challenges show why it is a great idea to avoid file corruption and retain the quality of your photos.
