Question details
User needs a solution for PDF pages getting cropped during the file optimization process.

- Product
- Adobe Acrobat Standard 2017
- Device & OS
- not provided
- Scenario
- Optimizing PDF documents that contain specific elements, particularly handwritten forms.
- Observed behavior
- Certain pages get unexpectedly cropped after optimization, an issue that began occurring in the workflow after January 2020.
Before altering your optimization settings, ensure you keep the original unoptimized PDF file to prevent permanent data loss during testing.
Reset Optimization Profiles and Adjust Settings
Resetting the optimizer profile to default and avoiding aggressive cleanup parameters can stop Acrobat from mistakenly cropping page content.
Acrobat's optimizer might interpret handwritten forms or specific embedded content as irrelevant objects if the cleanup settings are too aggressive. Resetting these parameters ensures standard dimensions are preserved.
Open your original PDF in Acrobat 2017. Go to 'File' > 'Save As Other' > 'Optimized PDF'.
In the PDF Optimizer dialog box, locate the 'Settings' dropdown menu at the top and change it to 'Standard' or 'Default' to clear any aggressive custom profiles.
Click on 'Discard Objects' and 'Clean Up' from the left panel. Ensure that aggressive removal options that might affect annotations or form fields are unchecked.
Click 'OK' to save the optimized file. Open both the original and new files side-by-side to verify the pages are no longer cropped.

Flatten Handwritten Forms Before Optimization
If only specific handwritten forms are affected, flattening the pages prior to optimization ensures the content is locked into the background layer.
Optimize PDFs Without Cropping Using WPS Office
Avoid page cropping and layout distortion by using the built-in PDF compression tool in WPS Office. It safely reduces file size while preserving handwritten forms and original page dimensions.
- 1. Open your PDF: Launch WPS Office and open the PDF document you want to optimize.
- 2. Navigate to Tools: Click on the 'Tools' tab located on the top ribbon.
- 3. Select Compress: Click the 'Compress' option to open the optimization settings window.
- 4. Apply Optimization: Choose your desired compression level and click 'Compress' to safely reduce the file size without cropping.

Frequently Asked Questions
Why do PDF pages get cropped when optimizing?
Aggressive cleanup settings or transparency flattening processes during optimization can sometimes misinterpret handwritten fields or embedded annotations, causing the software to mistakenly trim or crop the page boundaries.
How can I prevent handwritten forms from being altered during compression?
Flattening the PDF before running the optimizer is the best approach. This locks the handwritten annotations and forms into the document's background layer, preventing the optimizer from modifying them.
Will updating Acrobat fix the cropping bug?
It is highly possible. If the cropping issue started abruptly after a certain date, it might be tied to a specific patch. Installing the latest updates for Acrobat 2017 can often resolve these introduced workflow bugs.
