# Merge PDF for contractors

_Updated July 2026 · Arthize · https://arthize.com/for/contractors/merge-pdf_

Arthize lets construction and trades teams merge PDF files in a private workspace — free, with no watermark. Merging PDFs combines several documents — and any JPG or PNG pages — into one file losslessly, so text stays selectable and images stay sharp.

## Why contractors merge PDF files

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 merge 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 merge PDF files

A proper merge is lossless because it copies existing page objects instead of re-rendering them.

You can reorder individual pages, not just whole files, before merging.

Merging never adds a watermark, even on the free plan.
