How do I compress images?

Compressing images is essential for improving website speed without sacrificing too much quality. There are several methods and tools to compress images, depending on your needs and workflow. Here’s a guide on how to compress images:

1. Use Online Compression Tools

If you need quick and easy compression without installing software, online tools are a great option:

  • TinyPNG (tinypng.com): Compresses PNG and JPEG images efficiently with minimal loss in quality.
  • JPEG-Optimizer (jpeg-optimizer.com): Specializes in compressing JPEG files and allows you to resize images as well.
  • Optimizilla (imagecompressor.com): Supports batch compression of JPEG and PNG images.

2. Image Compression Software

For more control over compression settings, desktop software tools are available:

  • Adobe Photoshop: In Photoshop, go to File > Export > Save for Web (Legacy). Here, you can adjust the quality and format settings for JPEG, PNG, and GIF files.
  • GIMP (Free): An open-source alternative to Photoshop. You can export images in different formats and adjust the quality settings to compress images.
  • ImageOptim (Mac): Automatically compresses images by removing metadata and optimizing file size while preserving quality.

3. Use Image Compression Plugins (for WordPress Users)

If you're running a WordPress website, you can automate the compression process with plugins:

  • Smush: Automatically compresses images as you upload them and also offers bulk optimization.
  • Imagify: Allows you to optimize images in various compression levels (normal, aggressive, ultra) and can bulk compress existing images.
  • ShortPixel: Compresses images, including WebP format, and automatically serves optimized images.

4. Use Command Line Tools (for Advanced Users)

Developers who handle a large number of images may prefer using command-line tools:

  • convert input.jpg -quality 85% output.jpg

  • jpegoptim and optipng: These tools allow you to compress JPEG and PNG files without visible quality loss.
5. Adjust Image Format
  • JPEG: Best for photographs or complex images. Adjust the quality between 60-85% for a good balance between size and quality.
  • PNG: Best for images with transparency or fewer colors, like logos. Use tools to optimize PNG size without losing transparency.
  • WebP: Consider converting images to WebP format, which provides better compression while maintaining high quality. Tools like ShortPixel or online converters can handle this conversion.
6. Resize Images Before Uploading
Compressing images is important, but resizing them before uploading can drastically reduce file size. Tools like Adobe Photoshop, GIMP, or online services like PicResize (picresize.com) allow you to adjust image dimensions to fit your website's needs.
7. Enable Lazy Loading
In addition to compression, using lazy loading ensures that only the images visible in the user's viewport are loaded, further improving speed. For WordPress, plugins like Lazy Load by WP Rocket or Smush include this feature.
By using these tools and techniques, you can significantly reduce image file sizes, improving website performance while maintaining visual quality.
