Tips for Best Results

1. Choosing the Right Quality

• For web use, a quality of 0.6 to 0.8 typically provides good compression without noticeable quality loss.
• For archival purposes, consider higher values like 0.9.

2. Handling Large Images

• Resize large images to fit within the tool's maximum dimensions (800px) before uploading for better performance.

3. Browser Compatibility

• Use modern browsers to ensure full functionality. Older browsers might not support the required APIs.

Advanced Customizations

1. Modify Maximum Dimensions

• The maximum width and height are set to 800px in the code:

  javascript
  const MAX_WIDTH = 800;
  const MAX_HEIGHT = 800;
  

  Change these values to suit your needs.

2. Change Compression Format

• The output format is set to JPEG:

  javascript
  const compressedImage = canvas.toDataURL('image/jpeg', quality);
  

  To use PNG or WebP, replace 'image/jpeg' with 'image/png' or 'image/webp'.

3. Simulate Real-Time Progress

• Adjust the progress and interval logic for more realistic feedback:

  javascript
  let progress = 0;
  const interval = setInterval(() => {
    progress += 20; // Adjust speed
    progressBar.style.width = `${progress}%`;
  }, 1000);
