Form Logic Designer
Design dynamic behaviors using a glassmorphic node canvas and inject interactive AcroJS logic into PDF forms.
Form Logic Configuration
Drag and drop an AcroForm PDF here to design field dependency rules.
How to Use
Upload Interactive PDF
Provide a PDF file that already has active form fields (AcroForm).
Map Out Logic in Canvas
Connect fields as nodes. Link output events (change, blur) to target actions (show, hide, calculate, disable).
Compile and Download
Inject the compiled JavaScript logic into the PDF dictionary and save the final smart document.
About This Tool
Interactive Form Logic Designer is a pioneering tool that fills a massive gap in PDF capabilities: creating active, responsive fields instead of flat, dead forms.
Through our visual canvas featuring "glowing glassmorphic nodes" (built on React Flow), form fields are represented as connected modules. You can drag links to define relationships: e.g., when a checkbox is checked ➜ enable a text input ➜ auto-calculate values and update a total field.
Once designed, the AcroJS engine compiles the logic into official Acrobat JavaScript and injects it into the '/AA' (Additional Actions) dictionaries of the AcroForm. The interactive behaviors are then executed natively inside any standard PDF reader.
Use Cases
Smart Sales Contracts

Automated Expense Forms
Sum up multiple expense lines and compute taxes dynamically without manual calculation.
Interactive Questionnaires
Skip irrelevant questions based on previous answers, providing a cleaner mobile filling experience.
