Why Resize Images?
1. Web Speed (SEO)
Large images are the #1 reason for slow websites. If you upload a 4000px wide photo from your phone directly to your blog, it will load slowly. Resizing it to 1200px or 800px can reduce the file size by 90% without losing visible quality.
2. Social Media Requirements
Every platform has a preferred size. Uploading the wrong aspect ratio can result in your content being cropped unexpectedly.
- Instagram Square: 1080 x 1080 px
- Instagram Portrait: 1080 x 1350 px
- YouTube Thumbnail: 1280 x 720 px
- Twitter/X Post: 1600 x 900 px
3. File Types Explained
- JPEG: Best for photographs. Small file size but does not support transparency.
- PNG: Best for logos, screenshots, and graphics. Supports transparent backgrounds but file sizes are larger.
- WebP: The modern standard. It offers quality equal to JPEG but with 30% smaller file sizes. Highly recommended for websites.
