1. Choose the Right File Format
The different file formats are for different purposes. Here’s a quick guide:
- JPEG: Best used for photographs because they result in smaller file sizes.
- PNG: Best for logos and images that need to be transparent but larger in size.
- WebP: A modern format offering high-quality images with smaller file sizes (recommended for WordPress).
Fact: According to Google, switching to WebP format can reduce image file size by 25–34% compared to PNG or JPEG.
2. Compress Images Before Uploading
Image compression reduces file size without noticeable quality loss. There are two main types:
- Lossless Compression: Maintains all image information; yields slightly larger files. –
- Lossy Compression: Significantly reduces file size but may ever so slightly suffer in quality. –
Recommended Tools for Compression –
- Online Tools: TinyPNG, JPEG Optimizer, or Squoosh. –
- WordPress Plugins: Use the plugins Smush or ShortPixel to automatically compress images on upload.
3. Resize Images to Fit Your Website
Uploading images larger than necessary is a common mistake. Resize images to the exact dimensions required by your WordPress theme.
How to Resize Images
- Use free tools like Canva or GIMP before uploading.
- Alternatively, plugins like Resize Image After Upload handle resizing automatically.
Pro Tip: Always set the maximum width and height for images in your theme’s settings.
4. Use Lazy Loading for Better Performance EN
Lazy loading loads the images only when they are about to enter into the user’s viewport. This reduces the initial page load and saves bandwidth.
How to Enable Lazy Loading
- WordPress natively supports lazy loading since version 5.5.
- For extra customization, consider the following plugins: Lazy Load by WP Rocket.
