How to Compress Images for the Web

Large images are one of the biggest reasons websites load slowly. Whether you’re uploading photos, graphics, or hero banners, properly compressing your images before adding them to WordPress ensures faster load times, better SEO, and a smoother experience for your visitors. The good news is that optimizing images for the web is simple with the right tools and techniques.

1. Why Image Compression Matters

Every image on your site adds to your page size. Uncompressed images can be several megabytes each, which slows your site down and hurts your search rankings. Compressing images reduces their file size without noticeably affecting quality, keeping your site fast and user-friendly.

2. Choose the Right File Format

Selecting the ideal format for each image helps reduce file size while keeping visuals sharp. In most cases:

  • JPG – Best for photos and large hero images.
  • PNG – Best for logos, icons, or graphics that need transparency.
  • WEBP – Smaller file size than JPG and PNG, with strong quality. Excellent for most images.
  • SVG – Ideal for logos and vector graphics when supported.

Whenever possible, use WEBP or SVG formats for faster performance.

3. Resize Images Before Uploading

Most images coming from a camera or phone are far larger than needed for the web. Before compressing, resize images to the maximum size they will appear on your site. For example:

  • Full-width hero images: around 1600–2000px wide
  • Blog post images: 1200px wide
  • Thumbnails or smaller graphics: 400–800px wide

Resizing alone can reduce file size dramatically.

4. Use Image Compression Tools

There are many reliable tools that compress images without losing quality. A few popular options include:

These tools remove unnecessary metadata and optimize images to load quickly while still looking sharp on modern screens.

5. Use WordPress Plugins for Automatic Compression

If you prefer an automated solution, WordPress has plugins that optimize images as you upload them:

These tools can convert files to WEBP, compress images in bulk, and help keep your media library optimized over time.

6. Test Page Speed After Optimizing

After uploading optimized images, test your page using tools like Google PageSpeed Insights or GTmetrix. This helps confirm your images are loading efficiently and identifies any that still need optimization.
