JPEG-COMPRESSOR

JPEG-COMPRESSOR is a high-performance tool for compressing JPEG images using Rust and WebAssembly. It provides a simple API to reduce the file size of JPEG images while maintaining visual quality, making it ideal for web and backend applications.

Features

• ⚡ Blazing Fast Compression: Built with Rust for maximum performance.
• 🌐 Web-Compatible: Compiled to WebAssembly for seamless use in browsers.
• 📦 Simple API: Compress images directly from base64 strings.
• 🎚️ Custom Quality: Adjust compression level (0-100) to balance quality and size.
• 🔄 Lossless Option: Supports lossless compression for minimal quality degradation.

Installation

Rust (via GitHub)

Add this to your Cargo.toml:

[dependencies]
jpeg-compressor = { git = "https://github.com/jeancarlos1111/jpeg-compressor.git" }

Web (npm)

 npm install @jeanzg32/jpeg-compressor

Usage

Rust

use jpeg_compressor::compress_jpeg;

fn main()-> Result<String> {
    let base64_image = "data:image/jpeg;base64,/9j/4AAQSkZJRgABAQEASABIAAD/...";
    let quality = 80;
    let compressed = compress_jpeg(base64_image, quality)?;
    println!("Compressed size: {}", compressed.len());
    Ok(())
}

JavaScript (WebAssembly)

import init, { compress_jpeg } from '@jeanzg32/jpeg-compressor';

async function compressImage() {
  await init();
  const base64Image = document.getElementById('image-input').value;
  const quality = 75;
  try {
    const compressed = await compress_jpeg(base64Image, quality);
    console.log('Compression success:', compressed);
  } catch (error) {
    console.error('Compression failed:', error);
  }
}

[!NOTE] Calidades menores a 80 pueden producir artefactos visibles.

No soporta otros formatos de imagen (solo JPEG).

Para imágenes muy grandes, considerar usar Web Workers.
