Tool for real estate agents and photographers
MLS photo resizer for listing photos
Drop in a full shoot and get every photo back at an MLS-ready size: 2048 x 1536 px by default, saved as JPEG, with an optional file size cap. The resizing happens in your browser, so nothing is uploaded. It costs nothing and needs no account.

JPG, PNG or WebP. HEIC in Safari. Up to 100 photos per batch.
Photos are resized in your browser. Nothing is uploaded to RoomLift or to any other server.
Cropping trims evenly from the center. Photos are never enlarged.
85 to 95 is the usual range for MLS.
Quality is lowered until each file fits. 10 MB is within the limit of every MLS in the table below.
Output is always JPEG, with the camera's rotation applied. Transparent areas become white.
MLS photo size requirements
There is no single national MLS spec, but the core numbers are consistent. These come from our MLS photo requirements guide and are the presets in the tool above.
| Specification | Minimum | Recommended | Ideal |
|---|---|---|---|
| Resolution | 1024 x 768 px | 2048 x 1536 px | 4096 x 3072 px |
| Megapixels | About 0.8 MP | About 3 MP | About 12 MP |
- File format: JPEG is accepted by every MLS, and some also take PNG. HEIC, WebP, TIFF and RAW are not accepted, so this tool saves every photo as JPEG.
- File size: most MLS systems cap each photo at 10 to 20 MB. A JPEG at 2048 x 1536 usually lands between 2 and 6 MB, and anything under 10 MB clears every limit listed below.
- Aspect ratio: 4:3 and 3:2 are the ratios MLS systems and their syndication partners display most. A 16:9 photo may be cropped.
- Orientation: shoot landscape. Some MLS systems do not auto-rotate, so the tool applies the camera's rotation data to the pixels.
File size and photo count limits by MLS
Five large regional systems, as listed in the guide.
| MLS | Max file size per photo | Photos per listing |
|---|---|---|
| CRMLS (California) | 15 MB | 100 |
| NWMLS (Pacific Northwest) | 10 MB | 40 |
| Bright MLS (Mid-Atlantic) | 20 MB | 50 |
| HAR (Houston) | 15 MB | 40 |
| GAMLS (Georgia) | 15 MB | 50 |
MLS rules are updated from time to time. Check your own MLS or local association for its current limits before a large upload.
How to resize photos for MLS
- Add your photos. Drag JPG, PNG or WebP files onto the drop area, or press Enter on it to browse. A batch holds up to 100 photos.
- Pick a size. Recommended (2048 x 1536) suits most MLS systems. Choose High resolution (4096 x 3072) for high-resolution displays, or enter a custom long edge or a width and height.
- Set the quality and an optional file size cap. A JPEG quality of 85 to 95 keeps photos visually identical at a much smaller file size. Enter a cap such as 10 MB and the tool lowers the quality step by step until each file fits.
- Resize and download. Photos are processed one at a time. Check the new dimensions and file size of each photo, then download them one by one or together as a ZIP.
When to resize, and when not to
If an export already sits at or above the recommended size and under your MLS file size limit, upload it as it is: extra pixels look better on high-resolution screens. Resize when the MLS rejects a file for its size, when uploading 40 full-resolution frames takes too long, or when a client asks for web-sized copies. The tool never enlarges a photo, so an original smaller than the target keeps its own dimensions.
