Shrink massive image-heavy scanned PDFs down to manageable sizes cleanly.
Compress PDF freeScanned documents created by physical scanners or phone scanner apps consist of heavy bitmap images, causing file sizes to balloon to 30MB+ for just a few pages. Our scanned PDF compression algorithm downsamples image DPI and removes redundant color profiles so your document shrinks drastically while staying completely legible.
