Airbnb Photo Size Requirements, and How to Meet Them on a Mac

Airbnb’s photo tour help page says “make sure your photos are at least 1024 x 683 pixels”, and every room needs at least one photo to appear in the tour. Neither that page nor Airbnb’s photo guide states a file-size cap or a format list.

That guide adds three things worth acting on. You need at least 5 photos to start, horizontal shots are the advice, and Airbnb automatically crops photos into squares for search results and your listing.

The practical reading: Airbnb sets a floor, not a ceiling. A 4032 × 3024 iPhone frame is about 12 million pixels, far past the 1024 × 683 minimum (about 0.7 million), so the question is usually how large a file your connection and the upload form tolerate.

Anything from 2000 pixels on the long edge upward comfortably clears Airbnb’s 1024 × 683 floor. Because Airbnb crops to squares in search, the subject should sit in the middle of the frame; a wide shot of a bed against a wall can lose its edges.

Our recommendation, which is ours and not Airbnb’s: export once at 2000 to 3840 pixels on the long edge, as JPG at quality 75 to 80. If you also list on Vrbo, which prefers 3840 × 2160 or higher, export at 3840 and use the same files everywhere. Smol’s own default is to fit images inside 2000 × 2000 pixels, so raise it when you want the Vrbo-size source.

Vrbo’s photo guidelines ask for photos “at least 1024 x 683 pixels, but ideally… 3840 x 2160 pixels or higher”, in JPEG, PNG, WebP, AVIF or SVG format, with at least 6 unique photos per listing. The page states no maximum file size.

JPEG is on both Vrbo’s and Booking.com’s accepted lists, so it is the safe choice for one set of files.

Booking.com’s photo API documentation lists minimum dimensions of 300 × 300, maximum of 14000 × 14000, a 50 MB file limit, JPEG and PNG only, and 299 photos per property.

Those are the limits for software that connects to Booking.com, such as a channel manager. If you upload by hand in the Extranet, check the requirements shown there.

Platforms change these pages, so check them before a big upload.

Set the output to JPG, quality 75 to 80, and a maximum dimension that matches the platform. Smol sets quality and pixel size, not output bytes, so check the largest file in the output folder.

Smol also has a target-file-size mode (Neural), where you type a size from 4 to 4096 KB. It aims for a band, not a hard ceiling, and it is slow: about 28 seconds for one 768 × 512 image. Use it for the odd photo that will not fit.

For scale, on 24 small Kodak test photos (768 × 512, high-quality JPEGs, default settings), Smol’s JPEGs came out 69.3% smaller. Camera-size files will behave differently. Method and raw data are on the benchmark page.

Do it once per property, then reuse the same files on every platform.

1. 1

   Copy the shoot to a folder on your Mac

   Originals stay untouched by default. Smol writes a copy with a _compressed suffix.

2. 2

   Drag the folder into Smol

   Mixed batches work, so the floor plan PDF can ride along.

3. 3

   Choose JPG, quality 75 to 80, and a maximum dimension

   Use 2000 for Airbnb, 3840 if Vrbo is your main channel. Leave the fit mode on fit so nothing is cropped.

4. 4

   Compress, then sort the output by size

   If any file is still too big for a form, rerun just those at a lower quality.

5. 5

   Open one output file and check it

   Look at a bright window shot and a dark bedroom for banding, and confirm the file opens in your upload form.

If you keep shooting at the same property, the watched-folder guide explains the automatic route. It is for folders of fresh, unoptimized files only, because a watched folder can make already-optimized files larger.

Usually it is the file, not you: an unresized camera frame, or an iPhone HEIC the form does not read. Booking.com’s API accepts JPEG and PNG only, and Vrbo’s guidelines list JPEG, PNG, WebP, AVIF and SVG, not HEIC.

• HEIC: use Compress with output JPG, not Convert. Converting to JPG ignores the quality setting and writes a large file. Background in why iPhone photos are HEIC and batch converting HEIC to JPG.
• Size: lower the maximum dimension before lowering quality; fewer pixels cuts bytes without softening detail as fast.
• Location: Smol strips GPS by default; verify one output with the GPS check.

Free tools come first, and for one or two photos they are enough.

The sips guide and every method compared go deeper. Hosts with a photographer should also see photographer delivery and agents can read the real estate listing page.

• You are on Windows, Linux or a phone only. Smol is a Mac app.
• You need pixel-identical output. Smol always re-encodes images, so for a lossless pass use ImageOptim (see the head-to-head).
• You have three photos. Preview resizes them in a minute and costs nothing.
• You need editing: exposure, straightening, cropping to a subject. Smol does not edit photos.
• You want a guaranteed byte cap on every file. Smol sets quality and pixels, so you check the result.
