Reduce in size and optimize no longer working

[brodie_0468]

Hi,

I have two clients who have been utilizing Adobe Acrobat for years and require their PDF proposals to be optimised and reduced in size, as they are font and image heavy. Despite updating Adobe as necessary in the last few months, their files haven't changed in size during either optimization or reduction. This is a growing concern as they will require the files to be reduced as necessary. Please assist.

@brodie_0468 A potential workable soluton is to review the specific optimization settings being applied. After opening the PDF in Adobe Acrobat Pro (as the standard Reader has limited optimization features), navigate to "File" > "Save As Other" > "Optimized PDF." In the "PDF Optimizer" dialog box, carefully examine each panel, particularly "Images," "Fonts," and "Transparency." For images, ensure that downsampling is enabled to an appropriate resolution for their intended use (e.g., 150 dpi for web, 300 dpi for print) and that lossy compression (like JPEG) is applied judiciously. Under "Fonts," verify that only necessary fonts are embedded; if a font is not crucial for viewing or printing, consider unembedding it. Also, check the "Transparency Flattening" settings if the documents contain transparent elements, as improper flattening can inflate file size. Experiment with different settings in each panel, saving a new version each time to compare file sizes, until you achieve the desired reduction without compromising the visual quality of the proposals.
