# Compress PDF for freelancers

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

Arthize lets freelancers and independent professionals 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 freelancers compress a PDF

A freelancer exports an invoice to PDF so it can't be edited, merges it with a proposal into one client packet, signs the contract on screen, and sends everything — without paying for Acrobat.

**Built for invoices.** Whether it's invoices, proposals, contracts, Arthize's compress pdf keeps the work inside your private workspace. A freelancer's client contracts and invoices are private business records that don't belong on a free public server.

## 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.
