How the listing photo resizer works
- Choose your photos, as many as the listing needs.
- Pick where they are going. Presets crop to the destination's shape from the center (or the top or bottom), or keep the original shape.
- Resize and download each photo, or all of them as one ZIP file. Files are saved as JPEG.
Photos are never enlarged beyond their original size, and nothing is uploaded: your browser does all the work.
Which sizes the presets use
The presets match the export sizes in the CurbShot app. They are sizes that look sharp on each platform, not the platforms' own rules, which change and, for MLSs, differ from one MLS to the next.
| Preset | Output | Shape |
|---|---|---|
| MLS | 1920 × 1280 px | 3:2 landscape, cropped |
| Zillow | Up to 3000 px on the long edge | Original shape kept |
| Airbnb | 2400 × 1600 px | 3:2 landscape, cropped |
| Vrbo | 3840 × 2560 px | 3:2 landscape, cropped |
| 1080 × 1080 px | 1:1 square, cropped | |
| 1080 × 1350 px | 4:5 portrait, cropped |
Platform rules to check before you upload
- Airbnb asks for landscape photos of at least 1024 × 683 pixels and says a bigger photo is better (Airbnb Help Center, checked October 2026). The Airbnb preset meets both.
- Zillow does not allow agent names, logos, contact details or watermarks on listing photos (Zillow Listings Quality Policy), so resize the clean photo, not a branded one.
- Your MLS sets its own minimum size, file size limit and photo count. Check its current photo rules; the MLS preset is a common size, not a guarantee.
Tips for sharper listing photos
- Shoot in landscape. A portrait photo cropped to 3:2 loses most of the room.
- Start from the largest original you have; resizing down keeps detail, resizing up cannot add it.
- Keep your untouched originals. Some MLSs ask for the original next to any edited photo.
- For better photos before you resize, see how to take real estate photos with an iPhone.
Frequently asked questions
Is the listing photo resizer free?
Yes. There is no sign-up, no watermark and no limit on how many photos you resize. It runs entirely in your browser, so it costs us nothing to run and costs you nothing to use.
Are my photos uploaded anywhere?
No. The photos are read, resized and saved by your own browser. They never leave your device, which you can check by turning off Wi-Fi after the page has loaded; the tool keeps working.
What size should MLS photos be?
It depends on your MLS, which sets its own minimum size, maximum file size and photo count. The MLS preset here uses 1920 × 1280 pixels in a 3:2 landscape shape, a common choice, but check your MLS’s current photo rules before you upload.
Why can’t it open my iPhone photo?
iPhones save photos as HEIF (.heic) by default, which most browsers other than Safari cannot read. Open the page in Safari, or set new photos to JPEG on your iPhone under Settings > Camera > Formats > Most Compatible.
Will resizing make my photos look worse?
Making a photo smaller keeps it sharp, and the tool never enlarges a photo beyond its original size. Cropping to a new shape removes the edges, so keep important details away from the edges or choose a preset that keeps the shape.
