MLS photo requirements: size, format and labels
Most MLSs want JPG photos, and the limits that trip agents up are file size, pixel dimensions, photo count and the labeling rules for edited images. A safe default is a JPG about 2,048 pixels on the long side and under 5 MB, which fits every MLS spec in the table below and Zillow's direct feed. Your MLS sets the final rules, so check its photo guide before you upload.
What are the photo limits at major MLSs?
Here is what several MLSs and Zillow publish in their own help pages. A dash means the source we checked didn't state that limit, not that there isn't one.
| Source | Max file size | Dimensions | Format | Max photos |
|---|---|---|---|---|
| Canopy MLS (NC) | 6 MB | 2048 × 1536 recommended; 3000 × 3000 max | JPG | 48 |
| MLS Now | 6 MB | At least 1024 × 768 | JPG | 50 |
| SDMLS (CA) | Under 15 MB recommended | Min 640 × 480; max 3072 × 2304 | — | — |
| Realcomp (MI) | 20 MB | Min 512 × 340 | — | — |
| CRMLS (CA) | — | — | — | 75 |
| Zillow direct feed | 5 MB | Min 330 × 220 | — | — |
Notice the spread. A photo that passes Realcomp at 18 MB would be rejected at Canopy, and a 3072 × 2304 image fits SDMLS but not Canopy's 3000 × 3000 maximum. Aim for the middle and you rarely have a problem.
What size and format should you use if you're not sure?
- Format: JPG. Save PNG and other large files for print and your own website.
- Dimensions: about 2,048 pixels on the long side, for example 2048 × 1536 for a 4:3 photo.
- File size: under 5 MB. That clears the MLS limits above and Zillow's feed limit.
- Orientation: horizontal. Vertical shots get cropped or shown small in many listing layouts.
- Color: standard sRGB, so colors look the same on every screen.
- No upscaling: don't enlarge a small phone photo to hit a size. It just gets blurry.
- Nothing on the image except labels your MLS requires. No logos, borders or text overlays.
If you use Listing Curator, every download already includes an MLS copy sized to 2,048 pixels on the long side, next to the full 4K PNG and your original photo.
How should you order your listing photos?
Order photos the way a buyer would walk through the home. It helps the listing read like a tour instead of a pile of pictures.
- Front exterior (your primary photo, subject to your MLS's first-photo rules)
- Entry or the first view inside
- Living room and other main gathering spaces
- Kitchen, then dining
- Primary bedroom and primary bath
- Other bedrooms and baths
- Bonus spaces: office, basement, laundry
- Back exterior, yard, patio or pool
- Neighborhood or community amenities, if your MLS allows them
When you include a virtually staged photo, place the original right before or after it. CRMLS requires that, and it reads more honestly everywhere else too.
What are the rules for the first photo?
The first photo becomes the thumbnail in search results, so it does the most work and gets the most scrutiny.
- MLS Now: the primary photo must be unaltered. A staged room or a day-to-dusk edit can't lead the listing.
- CRMLS: the original unaltered photo has to sit immediately before or after any altered image, which affects where a staged shot can go.
- Everywhere: use a photo of the actual property. Many agents lead with the front exterior so buyers can recognize the house on the street.
How do you label virtually staged or edited photos?
MLS labeling rules vary more than size limits do. Here is what several MLSs say:
| MLS | What it asks for |
|---|---|
| CRMLS (CA), Rule 11.5.2 | Label the altered image "Photo Modified," "Virtually Staged," "Digitally Altered" or "AI Altered." Submit the unaltered original and show it immediately before or after. Altering real-property elements is prohibited. A warning, then a $250 fine. |
| MLS Now, Rule 3.3 | On-image label such as "Virtually Staged" or "Digitally Altered," repeated in the photo caption. Primary photo unaltered. |
| SmartMLS (CT) | Staged photos "must have a stamp/watermark." An original "as is" photo is not required. |
| Stellar MLS (FL) | Virtual staging allowed. Don't swap or remove permanent fixtures, change paint colors, remove utility lines or cover material flaws. |
| NorthstarMLS (MN) | Proposed guidelines (July 2026): label staged or AI images and include an unaltered "Before" image. |
Virtually staged. Furniture is digital; the room is shown as-is in the next photo.
State law sits on top of MLS rules. California's AB 723 has applied since January 1, 2026, and Wisconsin's 2025 Act 69 takes effect January 1, 2027. See our guides on how to disclose virtual staging and laws by state. This is general information, not legal advice.
How can you resize and label photos for free?
Our free MLS photo labeler resizes photos for the MLS and adds a "Virtually staged" label, right in your browser. It works on photos from any source, not just Listing Curator.
- Open the labeler and add your staged photos.
- Let it resize them to MLS-friendly dimensions.
- Add the "Virtually staged" label.
- Download, then upload to the MLS next to the originals.
- Repeat the label in each photo caption if your MLS requires it.
MLS photo checklist
Before you hit upload
JPG, about 2,048 px on the long side, under 5 MB. Horizontal. Within your MLS's photo count. First photo follows your MLS's primary-photo rule. Walk-through order. Every staged or edited photo labeled on the image, and in the caption where required. Originals placed next to altered photos where required. No logos, contact details or text overlays. Permanent features unchanged in every edit.
Frequently asked questions
Can I upload PNG files to the MLS?
Several MLSs list JPG as the format, and PNG files are usually much larger. Convert to JPG before you upload.
Why do my photos look soft on listing sites?
Portals and MLSs often resize and compress what you upload. Starting from a sharp JPG near 2,048 pixels on the long side gives them the most to work with.
How many photos should I upload?
Enough to show every room and the outside, in order. The MLSs above cap uploads between 48 and 75, so most homes never hit the limit.
Can I put my logo on MLS photos?
Many MLSs restrict branding on listing photos; check yours. The safe habit is to carry only the labels your MLS requires and save branding for your own marketing.
Does a brightened or color-corrected photo need a label?
Basic exposure and color fixes are usually treated as normal editing; California's AB 723 exempts them when they don't change the representation. Changing the property itself is different, so check your MLS.
