# Compress PDF for nonprofits

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

Arthize lets nonprofit and NGO 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 nonprofits compress a PDF

A nonprofit merges its narrative report with financial statements into one grant submission, signs the board approval remotely, and compresses the package to meet a funder's upload limit — free.

**Built for grant reports.** Whether it's grant reports, financial statements, board minutes, Arthize's compress pdf keeps the work inside your private workspace. Donor and beneficiary data is sensitive; nonprofits need private processing without a costly subscription.

## 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.
