PNG optimizer website using oxipng via jSquash WebAssembly

Blairpng (live demo)

This website uses an oxipng WebAssembly binary via jSquash for lossless compression with batch file upload support all while maintaining complete data privacy without needing to use Rust tools or Squoosh.app which does not support batch uploading and has memory limitations making you unable to use the maximum compression level on low end devices.

Features

• Oxipng level 1-6 lossless compression
• Supports batch file uploading
• Supports optional image resizing using Pica (Lanczos3, etc)
• Supports optional color palette reduction using image-quantization
• Privacy focused (no server side execution)
• No Rust installation or tools needed

Settings (Level 1 = light but fast, 6 = max compress but slower)

Option	Technical Function	Default
level	Optimization preset (1-6)	3
optimize_alpha	Optimizes transparent pixels	true
interlace	Toggle Adam7 interlacing	false

Performance

Oxipng gives you significant file size reductions but maintains the original image quality.

• Efficiency: ~20-40% size reduction depending on the source (takes ... time stats here)
• Speed: Uses browser threading via Web Workers for multi core processing for batch uploads
