How to Compress Images for Website Hero Images on Windows
On Windows, a browser-based compressor avoids installing extra software. The hero is usually the largest element on a page and often decides how fast the page feels to load.
Recommended settings for website hero images
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 1920 px on the long edge |
| Quality | 78 |
| File size | 300 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
Open Edge, Chrome or Firefox, drag your photos from File Explorer into the drop zone, and set quality around 78.
