Sample Files for Testing
Download these carefully crafted sample files to test L0ss compression capabilities. Each file is designed to showcase specific compression features and demonstrate realistic compression ratios you can expect with your own data.
User database export with nested objects, repeated keys, and structured data. Perfect for demonstrating frequency-based key compression.
- 5 user records with consistent schema
- Repeated field names (firstName, lastName, emailAddress, etc.)
- Nested preferences and metadata objects
- Long key names ideal for compression
E-commerce order data with 13 records and 17 columns. Includes duplicate data, long text fields, and numeric values with unnecessary precision.
- Repeated city/state values (low-variance columns)
- Long text in notes column (truncation candidate)
- Precise decimal values (rounding opportunity)
- Consistent data structure across rows
Complete database schema with CREATE statements, INSERT statements, and complex queries. Features verbose syntax, comments, and transaction blocks.
- Single-line and multi-line comments
- Multiple consecutive INSERT statements (merge candidate)
- Long table aliases (user_table, product_catalog, etc.)
- Optional keywords (OUTER, PUBLIC, CASCADE)
- Schema changes (CREATE, DROP, ALTER)
Shopping cart class with extensive comments, JSDoc documentation, and verbose code. Demonstrates JavaScript minification and comment removal.
- Single-line and multi-line comments
- JSDoc documentation blocks
- Console.log statements (removal candidate)
- Whitespace-heavy formatting
- Long variable and function names
Product page with verbose DOCTYPE, redundant attributes, and formatted markup. Perfect for testing HTML5 minification techniques.
- Verbose HTML 4.01 DOCTYPE (normalization candidate)
- type="text/javascript" and type="text/css" (default removals)
- Boolean attributes with values (disabled="disabled")
- Whitespace-heavy formatting
- Meta tags and inline styles
Complex butterfly graphic with intricate line patterns and paths. Perfect for testing SVG path optimization and compression.
- Complex path data with thousands of points
- Verbose DOCTYPE and XML declarations
- Numeric precision optimization opportunities
- Large file size ideal for demonstrating SVG compression
