Flatten PDF for startups
Updated July 2026
Arthize lets startup founders 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 startups flatten a PDF
A founder exports the pitch deck to PDF, merges it with financials into a data-room file, and sends a SAFE for e-signature — without paying for enterprise document software.
Built for pitch decks. Whether it's pitch decks, cap tables, contracts, Arthize's flatten pdf keeps the work inside your private workspace. Fundraising materials and cap tables are highly confidential; private processing is critical.
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.
