How FormX Flattening Works
Merge interactive fields and XObjects into read-only static elements offline in three quick steps.
Upload AcroForm PDF

Scan Form Fields
The tool analyzes page resources and counts interactive widgets and layouts.
Flatten & Download

FormX & AcroForm Weld
Converts editable interactive form widget layers into flat vector paths embedded inside page graphics streams.
Resources Reference Audit
Identifies all XObjects and images referenced by PDF page resources to ensure accurate layer processing.
100% Client-Side Privacy
No documents leave your device. All dictionary tree parses and flattener loops run locally in browser tab RAM.
Frequently Asked Questions
Common questions regarding PDF forms and XObjects flattening.
Q.What is a FormX Object in a PDF?
FormXObjects are reusable PDF graphics templates (like signatures, logos, or headers) that can be referenced across multiple pages. Flattening them welds them permanently into the target content stream.
Q.Why should I flatten AcroForm fields?
Flattening converts interactive form input fields (like textboxes and radio buttons) into standard read-only text overlays. This prevents users from editing the values or changing the filled data in modern PDF viewers.
Q.Does this affect PDF text selection?
No. Standard text characters remain searchable and selectable. Only interactive input widgets, comment markup, and signature templates are converted to static vectors.
Q.Are my forms sent to a server?
No. The flattening process runs 100% locally in your browser memory via pdf-lib. Your confidential document data never leaves your computer.
