Flatten PDF for small businesses

Updated July 2026

Arthize lets small business owners and 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 small businesses flatten a PDF

A small business merges the month's receipts into one file, converts a proposal to PDF for a client, and password-protects a sensitive contract before emailing it — on a free plan with no per-seat cost.

Built for invoices. Whether it's invoices, contracts, receipts, Arthize's flatten pdf keeps the work inside your private workspace. A small business's financial and client documents are confidential and shouldn't be retained by a free ad-funded 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.
