Upload Errors and File Size Limits for Real Estate Listings

Updated April 11, 2026 · 8 min read

An upload error is frustrating when the message is vague. 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)
Widthabout 1920 px on the long edge
Quality78
File size400 KB or less

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

Upload Errors and File Size Limits

Most errors come from three causes: the file is too big, the dimensions are outside the allowed range, or the format is not accepted.

For real estate listings, convert to JPEG, resize to about 1920 pixels and compress below 400 KB. If the form lists its own limits, use those numbers instead.

Step by step with TheCompressJPEG

  1. Open the compress JPEG to 300 KB tool, or the main compressor for custom settings.
  2. Drop in your image. Nothing is uploaded; it is processed in your browser.
  3. Set the maximum width to 1920 and the target size to 400 KB.
  4. Press Compress, check the result and download it.

Quick tips

  • Write a size limit slightly below the stated maximum to leave a margin.
  • 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.
