Optimize file size and performance

Reduce the packaging master so the file opens reliably on laptops in the studio. Remove unused linked images, rasterize the huge background texture at production resolution, clean up hidden layers, and save a 'print-ready' copy with embedded fonts and optimized links. Then run through a quick preflight with Sam and confirm the file size is below 200MB before sending to the print vendor.

Before I optimize this bloated file, make it easy for reviewers to understand the trade-offs — identify the biggest contributors to file size, suggest which images to downsample or link instead of embed, note any visual risks of rasterizing effects, and flag anything that would make production hesitate, like missing bleed settings or embedded high-resolution raster layers.

I opened the packaging master and my laptop froze; the file is 1.3GB. I trimmed unused layers but I'm not sure which linked images or effects are creating the bulk—whether it's embedded TIFFs, oversized artboards, or multiple high-res textures. What is the most likely cause and the step-by-step action I should take now to get it down under 300MB without breaking the print output?

Our design files routinely balloon and slow down opening, saving, and handoffs, costing time and risking missed print deadlines. Where do we most consistently lose control — oversized linked assets, careless embedding, or over-complicated effects — and what single habit change will make the biggest dent in file size and speed across projects? Give a practical change the team can apply immediately.
