Tips for Getting Under 10MB
If your PDF is still over 10MB after compression, try these strategies:
- ✓ Split first, then compress — break a large PDF into smaller sections, then compress each one.
- ✓ Remove unnecessary pages — delete blank pages or pages that are not required for your submission.
- ✓ Use Black & White — if color is not required, convert images to grayscale before compressing (this reduces size significantly).
- ✓ Flatten the PDF — if the PDF has form fields or annotations, flatten them first to remove hidden data.
