Features:

Nine File Types, Generated Instantly

Create test files in all major formats: PDF, Word, CSV, JSON, PNG, JPG, SVG, Excel, and plain text. Perfect for testing uploads, APIs, file handling, and more.

Realistic Fake Data in Every File

PDF and Word files are fake business reports with an executive summary and four sections. CSV, Excel, and JSON files hold rows of fake people, companies, and addresses. PNG, JPG, and SVG files are 400x400 graphics. The Count setting also scales the content, so a higher count gives longer documents and more rows.

Batch Generation & Automation

Generate up to 100 files of one type in a single click for bulk upload tests and seeding test environments. Open, reveal, or delete each file right from the list.

Developer & QA Focused

Designed for developers, testers, and product teams. Use for UI/UX prototyping, backend testing, file validation, and more.

Offline & Privacy-First

All file generation happens locally on your machine, inside the SelfDevKit desktop app. No uploads, no tracking. Your data and files stay private and secure.
