Resolving the Not a PNG file Error in Photoshop: Practical Solutions & Fixes

Reasons for “Not a PNG file” Error in PhotoshopHave you ever encountered the frustrating “Not a PNG file” error in Photoshop? If so, you’re not alone.

This common issue can be both confusing and time-consuming to resolve, especially for those who are new to the world of image editing. In this article, we will explore the main reasons behind this error, as well as practical solutions to fix it.

By the end, you’ll have a better understanding of why this error occurs and how to troubleshoot it effectively.

Outdated Photoshop Version

Outdated Photoshop Version

One of the primary reasons for the “Not a PNG file” error in Photoshop is an outdated version of the software. If you are using an older version of Photoshop, it may not support certain file formats or have the necessary compatibility to open PNG files correctly.

Updating your Photoshop to the latest version can potentially resolve this issue.

File Extension Mismatch

Another possible cause for the “Not a PNG file” error is a file extension mismatch. Although a file may have the .png extension, the actual format of the image might be something else entirely.

This can occur if the file was downloaded from the internet or transferred from another device. In such cases, Photoshop recognizes the discrepancy and triggers the error message.

Fixes for the “Not a PNG file” Error in Photoshop

Update Photoshop to the Latest Version

Updating Photoshop to the latest version is often the simplest solution to fix the “Not a PNG file” error. Adobe frequently releases updates that include bug fixes, improvements, and compatibility enhancements.

By ensuring that you have the most recent version of Adobe Photoshop installed, you can eliminate any issues related to outdated software. To update Photoshop, follow these steps:

1.

Open Photoshop on your computer. 2.

Go to the “Help” menu at the top. 3.

Click on “Updates.”

4. If an update is available, follow the on-screen instructions to download and install it.

5. After the update is complete, restart Photoshop and try opening the PNG file again.

Check and Change the File Extension

If updating Photoshop doesn’t resolve the issue, the next step is to examine the file extension of the problematic image. This process involves checking the file’s properties and manually changing or correcting the extension.

To check and change the file extension, follow these steps:

1. Right-click on the PNG file that is displaying the error in Photoshop.

2. Select “Properties” from the drop-down menu.

3. In the “General” tab, locate the “Type of File” section.

4. If the file is not recognized as a PNG, note the current file extension.

5. Rename the file and replace the existing extension with “.png”.

6. If the file is recognized as a PNG, proceed to the next solution.

In some cases, changing the file extension manually may not be enough. You might need to open the file in a text editor such as Notepad to verify and modify the file header.

Here’s how:

1. Open Notepad on your computer.

2. Drag and drop the PNG file into the Notepad window, or use the “Open” option in Notepad to select the file.

3. Examine the first few characters of the file’s content.

– A valid PNG file header should start with “PNG” or “PNG”. 4.

If the file header is different or missing, replace it with a valid PNG file header. – Example: If the file starts with “JPG” instead of “PNG”, change it to “PNG” followed by the appropriate characters for a PNG file.

5. Save the changes made in Notepad.

6. Try opening the modified PNG file in Photoshop again.

In conclusion, encountering the “Not a PNG file” error in Photoshop can be frustrating, but it is not an insurmountable problem. Understanding the reasons behind this error, such as using an outdated Photoshop version or a file extension mismatch, is crucial for troubleshooting.

Updating Photoshop to the latest version and checking/changing the file extension can often rectify the issue. Armed with this knowledge, you can confidently resolve the “Not a PNG file” error and continue with your image editing endeavors.

Additional Fixes for the “Not a PNG file” Error

Resaving the Image as PNG

Sometimes, the “Not a PNG file” error in Photoshop occurs due to slight corruption or compatibility issues with the image file. In such cases, resaving the image as a PNG can often resolve the problem.

To resave the image as PNG, follow these steps:

1. Open the image file that is triggering the error in Photoshop.

2. Go to the “File” menu at the top of the program.

3. Click on “Save As” or “Save a Copy.”

4.

In the “Save As” dialog box, choose a location to save the file. 5.

In the “Format” or “Save As Type” dropdown menu, select PNG. 6.

Confirm the file name and other options, and then click “Save” to overwrite the existing file or create a new PNG file. In some cases, resaving the image might not be possible directly in Photoshop.

If this is the case, you can try using other image editing software, such as Paint, to convert the image to PNG format before reopening it in Photoshop.

Disable Use of Graphic Processor

Another potential solution for the “Not a PNG file” error is to disable the use of the graphic processor in Photoshop. Although the graphic processor can enhance performance, it can sometimes cause compatibility issues, resulting in errors when opening certain file formats, including PNG.

To disable the graphic processor in Photoshop, follow these steps:

1. Open Photoshop on your computer.

2. Go to the “Edit” menu at the top.

3. Select “Preferences” and then click on “Performance.”

5. Uncheck the box that says “Use Graphics Processor” or similar.

6. Click “OK” to save the changes.

7. Restart Photoshop and try opening the PNG file again.

Disabling the graphic processor may slightly impact the performance of Photoshop, particularly when handling large and complex files. However, this solution can help resolve the “Not a PNG file” error if it is caused by compatibility issues with the graphic processor.

Reset Photoshop Preferences

If none of the above solutions have resolved the “Not a PNG file” error, resetting the Photoshop preferences can often do the trick. Sometimes, incorrect settings or corrupted preference files within Photoshop can lead to errors when opening certain file formats, including PNG.

Here’s how you can reset the Photoshop preferences:

1. Close Photoshop if it is currently running.

2. Hold down the Shift + Ctrl + Alt (Windows) or Shift + Command + Option (Mac) keys simultaneously.

3. While holding down these keys, reopen Photoshop.

4. You will be prompted with a dialog box asking if you want to delete the Adobe Photoshop Settings file, also known as the preferences file.

5. Click “Yes” or “OK” to confirm and proceed with resetting the preferences.

Please note that resetting the Photoshop preferences will restore the program to its default settings. Any customized settings or presets you had previously applied will be lost.

However, this can often resolve various issues, including the “Not a PNG file” error.
