PDF Compressor Engine
Shrink PDFs with lossless structural optimization, or a stronger image-based mode for scanned documents.
Why use this tool?
Reduce a PDF's file size for email or upload limits. Lossless mode keeps text and images untouched; Strong mode re-renders pages as compressed images, which shrinks scanned PDFs a lot but makes text unselectable.
How to use it
- Select a PDF.
- Choose Lossless or Strong mode (and a level for Strong).
- Compare the before/after sizes and download if it's smaller.
