Windows 10: Are there any programs that can invert colors of images in a pdf file?

It doesn't have to permanently change them but while viewing only. With Acrobat, it only affects text if you change the document colors in accessibility options. But I want a program that can invert colors of all images in the document as well.

Step 1:

Convert PDF to images using any of the online tools. Example freepdfconvert

After conversion download images to your computer.

Open Microsoft PowerPoint > Create a blank presentation

Step 4:

On the INSERT tab, in the Images group, click Pictures. Then insert downloaded images.





Step 5:

Select the picture you want to recolor.

Step 6:

Under Picture Tools, on the Format tab, in the Adjust group, click Color and under recolor select any of the color option from 3rd row.





Step 6:

Now right click on a picture and select Save as Picture option. Do the same for all your pictures.

Step 7:

Windows 10 Scan App - PDF File Sizes Too Large

Hi Teja,

There are several reasons why the scanned file as PDF gets too large. Here are the most common causes:

• Dot Per Inch (DPI) - Most scanners will use 300 DPI for scanning images, which is the minimum DPI for the images that were printed after scanning. However, 72 DPI should be already enough for a PDF that is for screen reading.
• Saving the document as colored - Use black and white instead of color when scanning images to lessen file size. Make sure that any color settings such as
  Color Depth are also decreased.

If the suggestions have been tried but the PDF file size is still too large, the next option is to check the PDF software that is performing the conversion itself.

Let us know if you were able to lessen the PDF file sizes using the suggestions above or if you need further assistance.
