Bulk Certificate Generator: Bulk certificate creation for events, training, and classrooms

Overview

Bulk Certificate Generator - A web app that helps users create and download many personalized certificates from a single template and data source.

What Users Can Do

Feature 1: Upload an image template and place editable text placeholders anywhere on the certificate canvas.
Feature 2: Upload a DOCX template with {placeholder} syntax and auto-detect fields for bulk generation.
Feature 3: Import participant data via CSV or enter rows manually, then export generated certificates as PDF (and DOCX zip for DOCX templates).

Why I built this

I built this platform to solve a fundamental issue I faced while studying as follows -

• Creating certificates manually was repetitive and time-consuming.
• Existing tools were either expensive or lacked flexible template/data control.

After launch & Impact

• Reduced certificate generation work from hours to minutes for bulk datasets.
• Enabled both design-first (image template) and document-first (DOCX template) workflows in one tool.
• Improved reliability of certificate output by supporting structured placeholder-based generation.

Future Plans

• Add template saving and reuse for recurring events.
• Add advanced validation for CSV headers and placeholder matching.
• Add cloud export options and queue-based processing for very large batches.
