Fill PDF Templates with Dynamic Data
The Template Problem
You have a PDF template with placeholders like {NAME} and {DATE}. You need to fill thousands of them with different data. What happens when "Alice" fits but "Dr. Alexandria Konstantinopolis-Smith" doesn't? And what about subsetted fonts that are missing the glyphs you need?
Template API with Reflow Control
- Find and replace placeholders anywhere in your PDF -
{NAME},%NAME%, or any pattern you use - Register your own fonts to avoid subsetted font issues - replacement text uses the font you specify
- Choose how text reflows when it doesn't fit: BEST_EFFORT (auto-adjust), FIT_OR_FAIL (strict), or NONE
- Replace text or images - swap placeholders for dynamic content of any type
- Process thousands of documents in batch with the same template

API Calls
Simple Template API
Works instantly in guest mode - no API key required.
Why It Works
- Any placeholder syntax:
{NAME},%NAME%,[NAME]- use whatever convention your templates already have - Font registration: Register your own fonts to avoid subsetted font issues - full glyph coverage for any replacement text
- Reflow control: BEST_EFFORT auto-adjusts text to fit, FIT_OR_FAIL guarantees layout integrity, NONE for manual control
- Text and image replacement: Replace placeholders with text or swap images dynamically
- Batch processing: Same API works for one document or thousands
