Zillow Image Downloader

OK. I've made a chrome ext!!

Nice, this worked well. Thank you!

This also worked for me. So long as you scroll down in the Zillow image gallery to get all the images it will gather all the images in a zip folder for you. I targeted all the .webp images since that's the image type that Zillow requests/uses.

// Load JSZip library
const script = document.createElement('script');
script.src = "https://cdnjs.cloudflare.com/ajax/libs/jszip/3.7.1/jszip.min.js";
document.head.appendChild(script);

script.onload = function() {
    // Function to download the zip file
    function downloadZip(zip) {
        zip.generateAsync({type: 'blob'}).then(function(content) {
            const link = document.createElement('a');
            link.href = URL.createObjectURL(content);
            link.download = 'images.zip';
            document.body.appendChild(link);
            link.click();
            document.body.removeChild(link);
        });
    }

    // Function to gather and zip .webp image URLs from the network requests
    function gatherAndZipImages() {
        const imageUrls = [];
        const zip = new JSZip();
        const imgFolder = zip.folder("images");

        // Get all network requests from the Performance tab
        const requests = window.performance.getEntriesByType('resource');

        requests.forEach((request, index) => {
            if (request.initiatorType === 'img' && request.name.endsWith('.webp')) {
                imageUrls.push(request.name);
            }
        });

        if (imageUrls.length > 0) {
            console.log('Image URLs:', imageUrls);
            const downloadPromises = imageUrls.map((url, index) => {
                return fetch(url).then(response => response.blob()).then(blob => {
                    imgFolder.file(`image_${index + 1}.webp`, blob);
                });
            });

            Promise.all(downloadPromises).then(() => {
                downloadZip(zip);
            });
        } else {
            console.log('No .webp images found.');
        }
    }

    // Execute the function to gather and zip images
    gatherAndZipImages();
}

I haven't been able to get the above solutions to work but I was able to use @hzarrabi's snippet as a base for this script. Theirs should be more reliable but for some reason only a small number of the actual images were ever found in the resources... I expect this to be fairly brittle given it's relying on data attributes to select DOM elements but as of now (November 2, 2024) it works a treat. I threw in some options at the top for image format and sizes Zillow makes available as well.

const TARGET_FORMAT = "jpeg";  // Options: `jpeg` or `webp`
const TARGET_SIZE = "1536";  // Options: `1536`, `1344`, `1152`, `960`, `768`, `576`, `384`, `192`

// Load JSZip library
const script = document.createElement('script');
script.src = "https://cdnjs.cloudflare.com/ajax/libs/jszip/3.7.1/jszip.min.js";
document.head.appendChild(script);

script.onload = function() {
    // Function to download the zip file
    function downloadZip(zip) {
        zip.generateAsync({type: 'blob'}).then(function(content) {
            const link = document.createElement('a');
            link.href = URL.createObjectURL(content);
            link.download = 'images.zip';
            document.body.appendChild(link);
            link.click();
            document.body.removeChild(link);
        });
    }

    // Function to gather and zip image URLs from "media wall"
    function gatherAndZipImages() {
        // Gather the image URLs
        const mediaWall = document.querySelector('ul[data-cy="hollywood-vertical-media-wall"]');
        const sources = Array.from(mediaWall.querySelectorAll(`source[type="image/${TARGET_FORMAT}"]`));

        // Try to pull the largest src URL from a source's srcset
        // srcset is in the format "<url> <size>, <url> <size>" so we split it and try to grab the last (hopefully largest) URL
        // It shouldn't really matter, though, since the regex will replace the target size with the largest possible anyway
        const imageUrls = sources.map(source => {return source.srcset.split(",").at(-1).split(" ")[1].replaceAll(/_\d+.(jpg|webp)/g, `_${TARGET_SIZE}.${TARGET_FORMAT}`)});

        const zip = new JSZip();
        const imgFolder = zip.folder("images");

        if (imageUrls.length > 0) {
            console.log('Image URLs:', imageUrls);
            const downloadPromises = imageUrls.map((url, index) => {
                return fetch(url).then(response => response.blob()).then(blob => {
                    imgFolder.file(`image_${index + 1}.${TARGET_FORMAT}`, blob);
                });
            });

            Promise.all(downloadPromises).then(() => {
                downloadZip(zip);
            });
        } else {
            console.log(`No .${TARGET_FORMAT} images found.`);
        }
    }

    // Execute the function to gather and zip images
    gatherAndZipImages();
}

This latest one worked great for me! Just needed to remember to Continue in the debugger repeatedly for each image on the page. Thanks!

@jawaad-ahmad, glad it worked for ya! I completely forgot to remove that debugger statement. I edited my above comment to remove it so continuing the debugger shouldn't be necessary with the new coee

@jessereitz your script worked!!! Thank you!!!

@jessereitz works for me also. Thank you!

the last script from @jessereitz worked for me after a minor update for mediaWall:
const mediaWall = document.querySelector('div[data-testid="hollywood-vertical-media-wall"]');

Yeah I was getting mediaWall errors. So in summary, as of February 2025 this script worked for me after scrolling down to the bottom to load all the photos and pasting it in console. Combination of @jessereitz and @aarrtteemm's line update in one easy spot for copy paste:

const TARGET_FORMAT = "jpeg";  // Options: `jpeg` or `webp`
const TARGET_SIZE = "1536";  // Options: `1536`, `1344`, `1152`, `960`, `768`, `576`, `384`, `192`

    // Function to download the zip file
    function downloadZip(zip) {
        zip.generateAsync({type: 'blob'}).then(function(content) {
            const link = document.createElement('a');

            document.body.appendChild(link);
            link.click();
            document.body.removeChild(link);
        });
    }

    // Function to gather and zip image URLs from "media wall"
    function gatherAndZipImages() {
        // Gather the image URLs
        const mediaWall = document.querySelector('div[data-testid="hollywood-vertical-media-wall"]');
        const sources = Array.from(mediaWall.querySelectorAll(`source[type="image/${TARGET_FORMAT}"]`));

        const zip = new JSZip();
        const imgFolder = zip.folder("images");

        if (imageUrls.length > 0) {
            console.log('Image URLs:', imageUrls);
            const downloadPromises = imageUrls.map((url, index) => {
                return fetch(url).then(response => response.blob()).then(blob => {
                    imgFolder.file(`image_${index + 1}.${TARGET_FORMAT}`, blob);
                });
            });

            Promise.all(downloadPromises).then(() => {
                downloadZip(zip);
            });
        } else {
            console.log(`No .${TARGET_FORMAT} images found.`);
        }
    }

    // Execute the function to gather and zip images
    gatherAndZipImages();
}

Thanks!

@snab43 This is great. I scrolled down, pasted this into the Console and it worked exactly like I hoped.

I wanted to keep the photos of a house I'm interested in since the staging is really nice and I wanted it as inspo, and this made it so easy. A thousand thank-yous!

Thank you! This worked for me still as of March 2025! I had to type in "allow paste" and hit enter before pasting the code in.
