Merge PDF for nonprofits

Updated July 2026

Arthize lets nonprofit and NGO 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 nonprofits merge PDF files

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 merge 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 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.
