The Content editing tool is capable of editing images that are a part of the PDF. Images can be moved, deleted, or redacted using the content editing tool. The content editing tool can also change the compression, color space, and DPI of individual images within the document. Images from within the PDF can also be saved directly to your computer by using Save As which will allow you to choose a location to save the image to.
Note: Not all images displayed in a PDF are actually image content. In some cases the images may actually be many path objects combined together to form an image. Image content that is a path will not function the same and have limited editing abilities.
Move or Edit the image by doing the following
Image Content contains the following property settings:
Color space: displays the color format details of the image
Compression type: displays the image compression format used for the image
DPI Resolution: displays the DPI (dots per inch) of the image
Dimensions: the dimensions of the image in pixels
Size: the file size of just the selected image
The following options are available when editing the image.
Compression: Convert any image to either a JPEG, JPEG2000, FLATE, or JBIG2.
JPEG - lossy compression that will reduce image quality and size
JPEG2000 - less lossy compression that will reduce size and some quality
FLATE - Lossless compression does not reduce quality but may not always reduce file size
JBIG2 - Lossless compression that can only support black and white color space. Color images will be converted to black and white. Best for scanned documents with no images
Quality: Allows the image quality to be adjusted between 10-100%.
This will only affect JPEG or JPEG2000 images as these are the only formats that support image quality settings.
Color Space: Choose to either retain or convert the image colors to Grayscale or B&W.
Grayscale - Only supported with JPEG, JPEG2000, or FLATE. Best for full color images
B&W - Only supported by FLATE or JBIG2. Best for scanned documents with no images
DPI: Adjust the image resolution of all images that are larger than the option selected
Preset options include retain, 50, 100, 150, 200, 300, & 600 DPI
Custom option allows user to set any value between 50-1200 DPI
Cut or Copy image by doing the following
Delete or Redact image by doing the following
Note: The Redact option in Content editing functions exactly the same as using the PDF Redaction and will completely remove the selected image and replace it with a black bar.
You can use the Export All Images tool to save all the images within the document to your computer at once.
