MLS Photo Requirements: Size, Count and Editing Rules by MLS

Facts checked on October 20, 2026

Quick answer

There is no single national MLS photo standard; each MLS sets its own. Common requirements are a JPEG in landscape orientation, a recommended minimum size (MLS Now recommends at least 1024 x 768 pixels; SmartMLS recommends 1920 x 1080 or larger), a per-file size limit, a maximum photo count, and an unaltered primary photo. Most MLSs also ban branding, people and photos edited to misrepresent the property.

Examples from MLS rulebooks

  • MLS Now: At least 1024 x 768 recommended, no larger than 6 MB, landscape, up to 50 photos; primary photo must be unaltered.
  • SmartMLS: JPEG at 1920 x 1080 or larger recommended, 40 MB limit per photo, up to 40 photos.
  • HAR (Houston): At least six unique photos within 10 days of the list date for most property types.
  • NWMLS: No people or pets, no superimposed graphics or text, no manipulation that misrepresents what is for sale.

Size and file rules

MLS size numbers are usually recommendations, not hard minimums. MLS Now says that "for optimal quality, photos should be at least 1024 x 768 pixels (dimensions) but no larger than 6mb," in landscape orientation, with a maximum of 50 photos per listing (MLS Now). SmartMLS's connectMLS recommends "JPEG files that are 1920 x 1080 pixels in size or larger," with a "40mb file size limit per photo" and up to 40 photos per listing (SmartMLS).

Bigger is generally safer: a photo that is larger than the recommendation can be resized down, but one that is too small can't be improved by the MLS.

How many photos

Some MLSs set a minimum. HAR (Houston) requires "at least six (6) unique digital images" for single-family, townhouse-condominium, high-rise, multi-family and rental listings, loaded within 10 days of the list date (HAR MLS Rules).

The primary photo

MLS Now requires that "the primary image must be an unaltered current photo," with an exception for architectural renderings on new construction (MLS Now Rules §3). HAR says images where real property is digitally altered "may not be used as the primary image" (HAR MLS Rules).

What's not allowed in the photo

  • Branding and overlays. MLS Now prohibits "visible branding, watermarks, photos of agent/broker, marketing overlays, QR codes." NWMLS says it "will not accept photos with superimposed graphics or text" (NWMLS).
  • People and pets. NWMLS: "Absolutely no people or pets in any photos, including a reflection of the photographer in a window or mirror."
  • Misleading edits. NWMLS: "Do not manipulate images in a way that misrepresents what is for sale. Examples: removing the power lines, adding a lawn, adding a driveway, or removing any property defects."

Edits that change the property usually need a label, and some are banned outright. See AI-edited listing photo disclosure rules for state laws and MLS labeling rules.

FAQ

What size should MLS photos be?

It depends on the MLS. MLS Now recommends at least 1024 x 768 pixels and no more than 6 MB; SmartMLS recommends JPEGs of 1920 x 1080 pixels or larger with a 40 MB limit. Uploading a larger, high-quality JPEG in landscape orientation is the safe choice.

How many photos can I upload to the MLS?

Limits vary: MLS Now allows up to 50 photos per listing and SmartMLS up to 40. Some MLSs also set a minimum, such as HAR's six unique photos for most residential listings.

Can I put my logo or watermark on MLS photos?

Usually not. MLS Now prohibits visible branding, watermarks and marketing overlays, and NWMLS won't accept photos with superimposed graphics or text. The exception is a required disclosure label on altered or virtually staged photos, which some MLSs mandate.
