# Flatten PDF for bookkeepers

_Updated July 2026 · Arthize · https://arthize.com/for/bookkeepers/flatten-pdf_

Arthize lets bookkeeping teams flatten a PDF in a private workspace — free, with no watermark. Flattening a PDF merges form fields, annotations and layers into the page, so nobody can change filled-in values and the file renders everywhere.

## Why bookkeepers flatten a PDF

A bookkeeper converts PDF bank statements to Excel to reconcile the month, merges receipts into a single file, and compresses the package to send to the client — privately.

**Built for bank statements.** Whether it's bank statements, receipts, ledgers, Arthize's flatten pdf keeps the work inside your private workspace. Client financial records must be processed privately and never retained by an outside service.

## What matters when you flatten a PDF

Flattening bakes form fields and annotations into the page so they can't be changed.

It fixes forms that display differently in different viewers.

A flattened PDF is the safe way to share a completed form.
