Compress Files and Folders Online - Free Archive Creator and Compressor

Understanding the Problem

Sharing multiple files via email, cloud storage, or file transfer services becomes cumbersome when dealing with dozens of individual files. Email attachments have size limits, cloud storage costs increase with usage, and file organization suffers without proper archiving. Traditional compression software requires installation, often includes bloatware, and may not support modern compression formats or cross-platform compatibility.

Tool Overview

Luxa's Archive Compressor creates compressed archives in ZIP, 7Z, and TAR formats with optimized compression ratios. The tool supports folder structures, maintains file permissions and timestamps, and offers adjustable compression levels from fast processing to maximum size reduction. All compression happens locally using WebAssembly technology for security and speed.

How to Use the Tool

Step 1: Upload Files and Folders

• Visit /archive/compress
• Click "Choose Files" to select individual files
• Use "Add Folder" to include entire directory structures
• Supports unlimited files and maintains folder organization
• Preview shows total uncompressed size before processing

Step 2: Choose Archive Format

• ZIP: Universal compatibility, moderate compression (recommended for most users)
• 7Z: Maximum compression ratio, smaller file sizes (best for large archives)
• TAR: Unix-standard format, preserves permissions (ideal for code/backups)

Step 3: Set Compression Level

• Fast: Quick processing, moderate compression (30-50% reduction)
• Normal: Balanced speed and size reduction (50-70% reduction)
• Maximum: Best compression, slower processing (60-80% reduction)

Step 4: Create Archive

• Click "Compress" to begin processing
• Real-time progress shows compression ratio and estimated completion
• Download compressed archive when processing completes
• File maintains original folder structure and metadata

Common Mistakes to Avoid

• Don't compress already-compressed files (JPG, MP3, ZIP) - minimal benefit
• Consider format compatibility when sharing across different systems
• Use descriptive archive names for better organization

Results and Benefits
