Compress PDFPDF
Make image-heavy PDFs practical to send without losing the original.
Compress PDF is built for scans, photo reports, brochures, and other documents where images create most of the weight. It estimates the result before processing, lets you balance image resolution and quality, then writes a smaller flattened copy with the exact bytes saved reported beside it.

Why it belongs

A size estimate before commitment
Foldout measures the loaded document and keeps the expected output visible while resolution and image quality are adjusted.
An honest quality tradeoff
Choose how aggressively images should be downsampled. Foldout makes the flattening behavior clear instead of presenting compression as lossless magic.
