Display Issues with 24-bit Images in PDFs after Latest Acrobat Reader Update

[匠佐76143669]

When opening a PDF with the latest version of Acrobat Reader (2025.001.20630),

I encounter display issues with images inside the PDF.
(This problem occurs only with 24-bit images; 8-bit, 4-bit, and 1-bit images are not affected.)

Could this issue be related to a bug introduced in the recent update?
Is there any configuration or workaround that could resolve this problem?

Hi @匠佐76143669,

Hope you are doing well. Sorry for your experience with viewing files in Acrobat.

We would like to investigate more on this. Would you mind sharing a few more pieces of information for further investigation?

1. The device OS and its version;

2. Do you see this with every file where there are 24-bit images, or specific to such comparison files?

3. Can you share a sample file with us to try and reproduce the issue in-house?

While you share the information, please check if the checkboxes in Menu > Preferences > Page Display are checked (screenshot shared below for reference):

Let us know how it goes.

Regards,
Souvik.

Thank you for your support. Please find my additional information below:

I am viewing the PDF on Windows 11.

1.From our investigation, the issue occurs mostly with the 32-bit version of Acrobat.
(It also occurs in some cases with the 64-bit version.)

2.It is safe to say that this happens with all 24-bit images.
(However, we confirmed that in some cases it does not occur with the 64-bit version of Acrobat.)

3.I am providing a sample PDF file (image.pdf).

Also, all Rendering settings are turned ON. (Turning them OFF did not change the result.)

Simmular issue. Color PDF at 300dpi.  Adobe 2025.001.20630 opens to an illegible immage. Adobe 2025.001.20577 and Apple's Preview open clean and clear immage. Attached is origional scanned document and Screen shots comparing image using Adobe ...20630 vs v …20577

I hope I’m not bothering you by following up again, but since this issue is still impacting our work, I wanted to kindly check if there have been any updates.
I would greatly appreciate any guidance you can share, or even an estimated timeline for when a response might be available.

Have you tried uninstalling and re-installing adobe? that has worked for us

[marcin_2962]

Uninstalling and re-installing work in 25.001.20630 64bit;  but not work when you have 25.001.20643 32bit or 25.001.20630 32 bit

[Richard344170453qhz]

Uninstalling and reinstalling worked for 2 days and reverted back to having the issue.

We're experiencing the same issue: over 1,200,000 files created from December 2017 to the present (consisting of 24-bit PNG screenshots) are failing to open after the latest update (just like yours). Since there's no solution, we're switching the default PDF viewer to EDGE.

The code below may not be very elegant, but it worked correctly for a long time (even if the images had resolutions other than 1024, 768)  

public static bool SavePDF(string pdfFilePath, List<string> images)
{
if (images.Count == 0)
return false;

iTextSharp.text.Document doc = new Document(new iTextSharp.text.Rectangle(1024, 768), 0, 0, 0, 0);

try
{
PdfWriter wri = PdfWriter.GetInstance(doc, new FileStream(pdfFilePath, FileMode.Create));
doc.Open();

doc.AddTitle(Path.GetFileNameWithoutExtension(pdfFilePath));

for (int i = 0; i < images.Count; i++)
{
iTextSharp.text.Image png = iTextSharp.text.Image.GetInstance(images[i]);

png.ScaleAbsolute(1024, 768);
png.Alignment = Element.ALIGN_CENTER;
png.CompressionLevel = 10;
doc.Add(png);
}
}
catch (DocumentException docEx)
{
return false;
}
catch (IOException ioEx)
{
return false;
}
catch (Exception ex)
{
return false;
}
finally
{
doc.Close();
}

return true;
}

We have had what looks like the same issue in our workplace and its taken up my whole day dealing with it! In the end we have found uninstalling and reinstalling adobe acrobat resolves it
