Uploads: “file too large” for PDFs that look small on screen

Scanned at 600–1200 dpi or embedded JPEG2000 in PDF can balloon size; some portals show size only on upload failure.

Open the PDF in Acrobat or a free optimiser, use “Save as other → Reduced size PDF” or re-export from preview at 150–200 dpi for text pages and 200 dpi for line drawings only.

Remove duplicate embedded copies of the same plan page. If the portal lists a max dimension (e.g. 10 MB) stay under 80% of that to allow form metadata.

Rasterised signatures pasted as high-res images should be re-scaled before embedding.
