# Compress PDF for photographers

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

Arthize lets photographers and studios 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 photographers compress a PDF

A photographer combines a gallery of images into one PDF proof, watermarks the previews, and compresses the file so the client can open it on their phone.

**Built for proof sheets.** Whether it's proof sheets, galleries, contracts, Arthize's compress pdf keeps the work inside your private workspace. Client shoots and unreleased galleries are confidential; private processing protects them.

## 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.
