• ⚡ Live Preview: Real-time command generation as you configure options
• 🗺️ Geographical Filters: Intuitive bounding box and polygon file support
• 🔧 Comprehensive Options: All osmconvert features including advanced memory management
• 📱 Responsive: Works perfectly on desktop, tablet, and mobile devices
• 💡 Smart Tooltips: Helpful explanations for complex parameters
• 📋 One-Click Copy: Easy command copying to clipboard

1. Open index.html in your web browser
2. Select your OSM input files
3. Configure output format and options
4. Copy the generated command and run it in your terminal

• All OSM formats: .osm, .osc, .osh, .o5m, .o5c, .pbf, .csv
• Multiple input file support
• Smart file size display

• Intuitive bounding box configuration (North/South/East/West)
• Polygon file support (.poly, .osm)
• Complete ways and multipolygons preservation
• Broken reference handling

• Author and version information control
• Tag modification with examples
• Fake data generation for compatibility

• Smart Memory Management: Hash memory configuration with intelligent recommendations
• Performance Tuning: Max objects and references configuration
• Conversion Options: Ways/relations to nodes conversion
• Statistics: Verbose output and processing statistics

The tool includes intelligent memory management recommendations:

• Automatically detects system RAM when possible
• Suggests optimal hash memory allocation
• Provides warnings for potentially problematic configurations
• Converts user-friendly GB values to osmconvert's MB format

• Large File Safe: Only reads filenames, never loads file content (prevents 100GB+ file issues)
• Efficient Processing: Smart memory allocation recommendations
• Fast Interface: Minimal JavaScript with efficient DOM updates

For detailed information about osmconvert parameters and usage, see:

• OSMConvert Wiki
• Built-in tooltips provide context-sensitive help for all options

The tool generates commands like:

osmconvert input.pbf --out-osm -o=output.osm -b=-74.0,40.7,-73.9,40.8 --complete-ways --drop-author --hash-memory=1200 --verbose
