Image Compression Guide

Image compression reduces file size while maintaining acceptable visual quality. This tool uses HTML5 Canvas technology to process images directly in your browser without uploading files to external servers.

Why Image Compression Matters

Unoptimized images slow down website loading and consume internet bandwidth. By compressing images, you get much smaller file sizes while maintaining good visual appearance.

How to Use

Step 1: Click "Choose Image" or drag-and-drop your image file. Supports JPG, PNG, and WEBP up to 10MB.

Step 2: Preview the comparison between original and compressed image. File sizes are displayed below each image.

Step 3: Adjust compression quality using the slider (10-100%). Quick presets available: High (90%), Balanced (75%), Small (50%), or Minimal (30%).

Step 4: Click "Compress Image" to see savings statistics. Once satisfied, click "Download" to save the compressed image.

Understanding Quality Levels

High Quality (85-100%): For professional photos or print. Minimal compression with barely visible differences. File size reduction around 20-40%.

Balanced Quality (70-85%): Best for most needs including websites and social media. Good balance between file size and visual quality. Savings around 40-60%.

Low Quality (50-70%): When file size is priority, like email attachments or limited bandwidth. Savings around 60-75% with acceptable quality.

Minimal Quality (10-50%): Maximum compression for thumbnails or previews. Savings up to 75-90% with visible quality reduction.

Privacy & Security

All compression processing happens directly in your browser. Files are never uploaded to any servers, ensuring your privacy is fully protected. After compression and download, all data is automatically cleared from browser memory.
