Best JPEG Quality Setting for Website Hero Images

Updated September 29, 2026 · 9 min read

Quality is the slider people touch first, yet it is often the least understood. 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

SettingStarting point
FormatJPEG (WebP where accepted)
Widthabout 1920 px on the long edge
Quality78
File size300 KB or less

These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.

Best JPEG Quality Setting

JPEG quality is not a percentage of the original. It controls how aggressively fine detail is discarded. Between 90 and 100 the file grows quickly for almost no visible gain, while between 70 and 85 most photos look identical at normal viewing size.

For website hero images, quality 78 is a good default. Drop toward 60 for small thumbnails or simple graphics, and stay nearer 85 for images people will zoom into.
