Resize Images Online: Optimize for Web Speed
Large image dimensions slow down website loading. Learn how to resize images to exact pixels and convert formats for optimization.
Resolution vs. File Size
These two are often confused, but they are different.
- Resolution: The number of pixels (e.g., 1920x1080). Determines how large the image appears on screen.
- File Size: The storage space occupied (e.g., 2MB). Directly affects loading speed.
Reducing resolution usually reduces file size. The key is to resize only to the dimensions you need.
Recommended Web Sizes
Here are standard max-widths based on usage:
- Fullscreen Background: 1920px
- Blog Post Content: 800px ~ 1200px
- Thumbnails/Cards: 400px ~ 600px
- Mobile Only: 640px ~ 750px
