Why Optimize Images for a Website?
Images are often among the largest files on a webpage. Reducing image dimensions and choosing an efficient format can reduce page weight and make pages faster to load.
Why Are Website Images So Heavy?
Images are frequently uploaded at much larger dimensions than they are displayed. PNG can also be inefficient for photographs, while high-quality JPG files may still be unnecessarily large.
Common causes
- Images are larger than their display dimensions.
- Photographs are stored as PNG.
- Compression settings are too high.
- Original camera files are uploaded directly.
- The same oversized image is used on desktop and mobile layouts.
How to Optimize Images for the Web
Resize images to realistic display dimensions and consider WebP for smaller files. Keep PNG when you need transparency or very sharp graphics.
Quick Fix: Prepare an Image for a Website
- Add the image.
- Choose WebP for efficient web delivery.
- Select the Web preset.
- Click Convert.
- Download the optimized image and upload it to your site.
Which Image Format Should I Use on a Website?
| Format | When to use it |
|---|---|
| WebP | A strong general-purpose choice for modern websites. |
| JPG | Good for photographs when broad compatibility is important. |
| PNG | Best for transparency, logos, screenshots, and sharp graphics. |
Balance Image Quality and Page Speed
Moderate compression is usually difficult to notice at typical website display sizes but can significantly reduce image file size.
Optimize Website Images Locally
Supported image conversion and resizing happens in your browser, allowing you to prepare site assets without routinely uploading originals to a remote conversion server.
Things to Know About Website Images
- Do not resize important print originals destructively; keep the original copy.
- PNG may be unnecessarily large for photographs.
- Very aggressive compression can produce visible artifacts.
- WebP support is strongest in modern browsers and software.
