PDF Forms
What Are PDF Forms?
PDF Forms allow you to upload existing PDF documents, add dynamic field placeholders, and automatically fill them with data from your app. When the PDF Form is generated, it will immediately download to your device with all the data populated.

Quick Start Overview
1. Upload a PDF
Give your PDF Form a name and select the PDF file to upload.
PDF Requirements:
- Only PDF files are allowed
- Maximum 10 pages per PDF
- Maximum file size is 1MB
- PDF cannot be encrypted or password protected
- English is the primary supported language
If your PDF doesn't download properly, open it in Chrome and click Print → Save as PDF, then use the new PDF in your PDF form upload.
2. Add Placeholder Fields
Open the PDF Form editor and add placeholder fields which will be automatically filled with data from your app.

- Text - Display text, numbers, dates, or currency values
- Checkbox - Show checkmarks based on conditions
- Image - Display images, logos, or photos

Auto-Detect Form Fields
If your PDF has embedded form fields, Tadabase can automatically detect them and create placeholders, saving you setup time.
