How to Compress Images for Blog Post Images Without Losing Quality
Strictly speaking, JPEG compression always discards something, but you can make the loss invisible. Articles often carry several images, and each extra megabyte delays the moment a reader can start scrolling.
Recommended settings for blog post images
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 1200 px on the long edge |
| Quality | 70 |
| File size | 150 KB or less |
These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.
How to Compress Images
The trick is to remove data the eye cannot see: extra pixels beyond display size and fine noise in flat areas. Resizing to 1200 pixels and using quality 70 does exactly that.
Compare before and after at 100 percent zoom. If you cannot spot a difference at the size people will see it for blog post images, you have compressed without visible loss.
