What this tool does
Inspect raster images used on PDF pages, list their pixel dimensions, and export a local JSON resolution inventory for optimization review.
PDF.js reads each page operator list and resolves image objects that the browser can decode. Pixel dimensions are recorded without uploading the file.
Effective print DPI cannot always be calculated because complex PDF transforms and reused image masks may hide placement size.

Tips for better results
- Treat tiny dimensions as a review signal, not automatic proof of poor print quality.
- Scan all pages when preparing a final print file.
- Compare repeated image names before assuming they are separate assets.
