Compress PDF for contractors
Updated July 2026
Arthize lets construction and trades 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 contractors compress a PDF
A contractor merges a bid, permit and change order into one project file, signs a document from their phone on site, and compresses a photo-heavy progress report to email the client.
Built for bids. Whether it's bids, permits, change orders, Arthize's compress pdf keeps the work inside your private workspace. Bids and client contracts are commercially sensitive; a private workspace keeps them secure.
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.
