Resize PDF Book for Lulu

I need my finished book interior converted to Lulu’s 6 × 9-inch trim size. At the moment I only have the final, flattened PDF—there are no original layout files—so the work will have to be done directly from that document or by recreating pages where necessary.

Simply shrinking the pages won’t be enough. The content must be properly adjusted to fit the new dimensions: text framed inside Lulu’s margin recommendations, images repositioned or scaled without distortion, headers and footers aligned, page numbers re-flowed, and any resulting blank pages removed. Once complete, the file should pass Lulu’s print pre-flight with embedded fonts, correct bleed where needed, and crisp resolution.

Deliverables
• Print-ready interior PDF at exactly 6 × 9 in (CMYK, embedded fonts, under Lulu’s size limit).
• Brief change log outlining what you modified so I can review quickly. Lulu error message below:
