How Image Size Affects Site Speed
Large images slow down your site and hurt Google rankings. Sites need fast loading, especially for mobile users on variable connections.
Target File Sizes for WordPress Images
Hero/banner images: under 200 KB. Thumbnails: under 50 KB. Product images: 100–150 KB.
Steps to Compress Images Before Upload
Use Pngtm.com to compress images before uploading to WordPress. Choose 80–85% quality for photos. Save the compressed version and upload it instead of the original.
Frequently Asked Questions
- What is the ideal image size for WordPress?
- Hero and banner images should stay under 200 KB for fast loading. Thumbnails work best under 50 KB, and product images between 100–150 KB. These targets balance quality with page speed for better Google rankings.
- Does compression reduce image quality?
- At 80–85% quality, the difference is barely noticeable to the human eye while saving significant file size. For photos, this range preserves sharpness and color. Use higher quality (90%+) only for graphics with fine detail.
- Should I compress images before or after uploading to WordPress?
- Compress before uploading. Use a tool like Pngtm.com to reduce file size, then upload the optimized version. This keeps your media library lean and avoids needing plugins to compress images after they are already on the server.
