## Why nonprofits sign 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 sign 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 sign a PDF

A clear electronic signature is legally valid for everyday agreements in most countries.

Cryptographic digital signatures bind the signature to the document for higher assurance.

You can fill form fields and sign in the same tool without printing.
