# Compress PDF for lawyers

_Updated July 2026 · Arthize · https://arthize.com/for/lawyers/compress-pdf_

Arthize lets legal teams compress a PDF in a private workspace — free, with no watermark. Compressing a PDF reduces file size — often 50–90% on image-heavy scans — by down-sampling images and stripping redundant data, while keeping text selectable.

## Why lawyers compress a PDF

Before a filing, a paralegal merges statements and exhibits into one bundle, adds consistent page numbers for the court, and redacts personal data so nothing privileged leaks — all inside a private workspace rather than a free public converter.

**Built for contracts.** Whether it's contracts, court bundles, exhibits, Arthize's compress pdf keeps the work inside your private workspace. Client files are privileged. A contract or discovery packet uploaded to a stranger's ad-funded server is a confidentiality risk lawyers can't take.

## What matters when you compress a PDF

PDF file size almost always comes from embedded images, not text.

Down-sampling scans to a lower DPI usually gets an image-heavy file under 1MB.

Light compression is visually lossless for most documents.
