Get the optimal photo dimensions, file size, and format for Idealista apartment listings. Learn how to resize, compress, and prepare property images for Spain's largest real estate portal.
Idealista is Spain's largest real estate portal, with millions of active listings and over 30 million monthly visits. If you are listing an apartment for sale or rent, your photos are the single most important factor in getting clicks. But poorly sized images can make even a beautiful apartment look unprofessional.
Idealista accepts JPG and PNG images. The minimum width is 600 pixels, and the maximum file size is 10 MB per image. The recommended specifications:
Idealista's gallery viewer is designed for horizontal images. When you upload a vertical photo, the portal adds large bars on both sides. Horizontal orientation also captures more of the room in a single frame, giving buyers a better sense of space. If you have vertical photos, use the crop image tool to convert them to a 4:3 horizontal ratio.
Most cameras shoot at resolutions far beyond what Idealista needs. The resize image tool lets you scale photos to exact dimensions. Set the width to 1600 pixels and let the tool calculate the height proportionally. For a typical listing with 20 to 30 photos, you can process all images at once.
After resizing, use the compress image tool to bring file sizes into the 200-600 KB range. A 1600×1200 JPG at quality 85 typically weighs around 300-400 KB — the sweet spot between visual quality and fast loading.
Since iPhone 7, Apple devices save photos in HEIC format by default. Idealista does not accept HEIC files — only JPG and PNG. You can change your iPhone settings to shoot in JPG, or convert your existing HEIC photos to JPG before uploading. SocialShrink includes a HEIC conversion tool that handles this directly in your browser.
Property photos contain sensitive information: personal belongings, family photos on walls, documents on desks, and street views that reveal the exact address. SocialShrink processes all images directly in your browser. Nothing is uploaded to a server, and no data is stored or shared.
For Idealista listings, shoot horizontal photos and target 1600×1200 pixels at a 4:3 aspect ratio. Compress to 200-600 KB per image in JPG format. Convert HEIC files to JPG first if shooting on an iPhone. Upload 20 to 30 photos ordered as a logical walkthrough of the apartment. Use SocialShrink's resize, compress, and crop tools to prepare the entire batch in your browser — no uploads, no accounts, no privacy concerns.
