How to Download Instagram Photos with Java Code
Instagram is one of the most popular social media platforms that allows users to share photos and videos with their followers. You might want to download some photos from Instagram for various reasons, such as backup, offline viewing, editing, or sharing on other platforms. However, Instagram does not provide an official way to download photos from its app or website. So, how can you do it?
One possible solution is to use Java code to download Instagram photos. Java is a general-purpose, object-oriented programming language that runs on multiple platforms. It has a rich set of libraries and frameworks that can help you perform various tasks, such as web scraping, data processing, and file handling. In this article, you will learn how to use Java code to download Instagram photos in a few simple steps.
java code to download instagram photos
The main steps involved in downloading Instagram photos with Java code are:
Getting an Instagram access token using the Instagram Graph API
Getting the photo URLs from Instagram using the Instagram Graph API
Downloading the photos with jsoup library
Prerequisites
Before you start coding, you need to have some prerequisites:
A Java development environment, such as Eclipse or IntelliJ IDEA
A Maven project with jsoup library as a dependency
An Instagram account and an access token for the Instagram Graph API
Jsoup is a Java library for working with real-world HTML. It provides a convenient API for fetching URLs and extracting and manipulating data, using the best of HTML5 DOM methods and CSS selectors. You can use jsoup to download photos from Instagram by fetching their URLs and saving them as files.
To get an Instagram access token, you need to use the Instagram Graph API, which is a tool that allows businesses and creators to manage their presence on Instagram from your app. The API can be used to get and publish media, manage and reply to comments, find hashtagged media, and more. To use the API, you need to have an Instagram Business or Creator account, register your app on Facebook Developer Platform, and generate an access token following the documentation.

Getting the Photo URLs from Instagram
Once you have your access token, you can use the Instagram Graph API to get the media data of a user or a hashtag. The media data includes information such as id, caption, media type, media url, timestamp, etc. You can use the media url field to get the photo URLs that you want to download.
To get the media data of a user or a hashtag, you need to make a GET request to the following endpoint:
or hashtag-id/media?fields=fields&access_token=access-token
The user-id or hashtag-id parameter specifies the id of the user or hashtag that you want to get media from. You can get the user id by using the User node of the API, or by using third-party tools such as [16]( You can get the hashtag id by using the Hashtag node of the API.
The The fields parameter specifies the fields that you want to get from the media data. You can use any of the fields listed in the Media node of the API, but for this task, you only need the media url field. The access-token parameter is your access token that you generated earlier. The API will return a JSON response that contains the media data in an array called data. You can parse the JSON response using the org.json library, which is included in jsoup. You can use the JSONObject and JSONArray classes to access the JSON objects and arrays, and use the getString method to get the value of a field. For example, you can use the following code to get the photo URLs from the JSON response: // import org.json library import org.json.JSONArray; import org.json.JSONObject; // get the JSON response as a string String response = ...; // parse the JSON response as a JSONObject JSONObject json = new JSONObject(response); // get the data array as a JSONArray JSONArray data = json.getJSONArray("data"); // loop through the data array for (int i = 0; i
The API may return more than one page of results if there are more than 25 media items. In that case, you need to use pagination to get all the results. The API will provide a next field in the JSON response that contains the URL for the next page of results. You can use this URL to make another request and get more photo URLs until there is no next field. You also need to be aware of the rate limits of the API, which limit the number of requests that you can make per hour. The rate limits depend on your app type and tier, and you can check them on your app dashboard. If you exceed the rate limit, you will get an error response with code 429. You can handle this error by waiting for some time and retrying later. Downloading the Photos with jsoup
Once you have all the photo URLs that you want to download, you can use jsoup to download them with ease. Jsoup provides a method called connect that allows you to connect to a URL and get its content. You can use this method to fetch the photo URLs and save them as files using the java.io library.
To download a photo with jsoup, you need to do the following steps:
Connect to the photo URL using jsoup.connect(url).get()
Get the photo element using doc.select("img").first()
Get the photo source attribute using element.attr("src")
Create a file output stream using new FileOutputStream(fileName)
Copy the photo source input stream to the file output stream using IOUtils.copy(inputStream, outputStream)
Close both streams using close()
For example, you can use the following code to download a photo with jsoup:
// import jsoup and java.io libraries import org.jsoup.Jsoup; import org.jsoup.nodes.Document; import org.jsoup.nodes.Element; import java.io.FileOutputStream; import java.io.InputStream; import java.io.OutputStream; // get the photo URL as a string String photoUrl = ...; // connect to the photo URL and get its content as a Document Document doc = Jsoup.connect(photoUrl).get(); // get the photo element as an Element Element photo = doc.select("img").first(); // get the photo source attribute as a string String src = photo.attr("src"); // create a file output stream with a file name of your choice OutputStream outputStream = new FileOutputStream("photo.jpg"); // copy the photo source input stream to the file output stream InputStream inputStream = new java.net.URL(src).openStream(); IOUtils.copy(inputStream, outputStream); // close both streams outputStream.close(); inputStream.close();
You can use a loop to download multiple photos with jsoup, and you can customize the file names and locations according to your preference. You can also handle any exceptions or errors that may occur during the download process, such as IOException or HttpStatusException. Conclusion
In this article, you have learned how to use Java code to download Instagram photos in a few simple steps. You have used the Instagram Graph API to get the photo URLs from Instagram, and jsoup library to download them as files. You have also learned how to handle pagination, rate limits, and exceptions.
To summarize, here are some of the pros and cons of using Java code to download Instagram photos:
Pros
Cons
You have full control over the download process and the file names and locations
You need to have some programming skills and tools to write and run the code
You can download photos from any user or hashtag that you have access to
You need to get an access token and follow the API rules and limits
You can use Java libraries and frameworks to perform other tasks related to the photos, such as editing, filtering, or analyzing them
You may encounter some errors or exceptions that you need to handle or debug
Some suggestions for further improvements and extensions of this project are:
You can use a graphical user interface (GUI) to make the code more user-friendly and interactive
You can use multithreading or parallel processing to speed up the download process and improve the performance
