Why MLS Systems Reject Your Photos

Every MLS system has specific requirements for listing photos. If your images don't meet these requirements, they get rejected, costing you time and potentially delaying your listing from going live. The most common reasons for rejection are:

  • File size too large: Most MLS systems cap photos at 5MB or 10MB
  • Wrong dimensions: Many require specific aspect ratios like 4:3 or 16:9
  • Wrong format: iPhone HEIC files are not accepted by most MLS platforms
  • Too many pixels: Some older systems have maximum resolution limits

  • Use the highest resolution your camera supports, then resize down for MLS upload
  • Strip EXIF/GPS data before uploading to protect seller privacy
  • Name your files with the property address for SEO (e.g., 123-Main-St-01.jpg)
  • Upload the maximum number of photos your MLS allows to increase engagement
