Compress PDF Locally

Start with a text-preserving local rewrite that removes metadata and repacks the file. Use visual compression only when scanned or image-heavy PDFs need stronger reduction.

Compression note

Safe rewrite removes document metadata and repacks the PDF without rasterizing pages. Visual compression is stronger for scanned files, but selectable text and vector detail may not be preserved.

faq

Practical boundaries before you process a file.

What does safe rewrite do?

It repacks the PDF with object streams and clears document metadata without rasterizing pages, so selectable text and vector content stay intact.

When should I use visual compression?

Use it for scanned or image-heavy PDFs when file size matters more than preserving selectable text and vector fidelity.
