How to Get a JPEG Under 400 KB for Real Estate Listings

Updated February 22, 2026 · 8 min read

Hitting an exact size limit is easier with a target-size compressor. Property listings rely on many wide photos, and fast-loading galleries keep buyers browsing longer.

Recommended settings for real estate listings

SettingStarting point
FormatJPEG (WebP where accepted)

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

How to Get a JPEG Under 400 KB

Type 400 into the target size box. The tool tries different quality levels and keeps the best one that fits. If even low quality cannot fit, it gradually reduces the dimensions until it does.

For very tight limits, crop first so the subject fills the frame. A tightly cropped image at 400 KB will look far better than a wide scene squeezed to the same size.

Quick tips

  • Process private images locally rather than uploading them to unknown servers.
  • Crop out distractions so pixels go to the subject.
  • Use WebP where it is supported and you control the page.
