Generator Tools
Create test files with eight browser-based generators: TXT, PNG, JPG, PDF, CSV, JSON, SVG, and QR codes. Size and option limits depend on the tool.
Sample JSON Files
Download ready-made JSON examples: objects, arrays, nested orders, GeoJSON, JSON Lines, and an invalid parser fixture. Generate larger 1 MB or 5 MB files locally.
Sample CSV Files
Download sample CSV files with 10–1,000 rows, quoting, semicolons, UTF-8 BOM, or no header. Generate 10,000 and 100,000 fictional test rows in your browser.
Sample & Dummy PDF Files
Download test PDFs with text, images, multiple pages, A4, Letter, and a known password. Generate approximate 1 MB and 10 MB dummy PDFs locally in your browser.
TXT File Maker & Text File Generator
Type or paste text and download it as a .txt file instantly, or generate a test TXT file of any size from 0.01 to 100 MB. Free and private—runs in your browser.
PNG Image Generator
Create a PNG image with exact dimensions and a custom color for placeholders, layouts, or upload tests. Generate and download it free, entirely in your browser.
JPG Image Generator

Test PDF File Generator
Generate a blank test PDF with 1–100 pages, A4, Letter or A3 size, orientation, and optional page numbers. Create upload and print fixtures in your browser.
CSV File Generator
Create CSV test data with random fictional records in fixed columns. Choose rows, headers, or an approximate target size and download locally in your browser.
JSON File Generator
Generate random JSON test data with a fixed record structure for API mocks, parsers, and uploads. Choose a record count or target size, locally in your browser.
