Flatten PDF for accountants
Updated July 2026
Arthize lets accounting and 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 accountants flatten a PDF
At month-end a bookkeeper converts PDF bank statements to Excel to reconcile them, merges receipts into a single expense file, and compresses the package small enough to email a client — without the data ever leaving a private workspace.
Built for bank statements. Whether it's bank statements, invoices, tax returns, Arthize's flatten pdf keeps the work inside your private workspace. Financial records carry account numbers and personal details. Accountants need those files processed privately and deleted, not retained by a free tool.
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.
