Dummy Large File Download - Choose from Different Formats and Sizes

Test files of various sizes can be useful for network and application testing. Below are download links to a few popular file sizes as well as a tool to generate custom size files. The files contain randomly generated binary data.

These locally generated files will download much quicker than the network downloaded files since their content's are generated on the fly. Their download speed is restricted only by your device's processor and storage drive speed.

All file sizes here conform the ISQ and IEC standards where 1KiB = 1024 bytes and 1KB = 1000 bytes. A lot of websites still refer to 1KB as 1024 bytes. If you do not receive the file size you are looking for try downloading the other variant.

To download a file with a custom size enter the size you would like below and click download. Note: these custom files are also generated locally, they should not be used as an indication of download speed.

Your #1 resource to download free test files either for speed test or for any other purpose! Our dummy files include audio, video, PDF, images, text, and many other formats. Simply click on the desired box below and download your test file. Here are our speed test files to download below.

Downloading our files is easy, simply click on your desired box (like 10GB, 5GB, 1GB, 512MB, 200MB, 100MB, 50MB, 20MB, 10MB, 5MB, 1MB, 100KB) above and it will start downloading the file. These files use IPv6 when available otherwise IPv4. All of our files are served over HTTP, FTP will be added soon.

Test files are used for different purposes. From a programming perspective, such files are used to test units and code. However, the main reason for our test files is to test downloading speed on different broadband or using tools.

Downloading time depends on your broadband package. However, we have tested downloading these files on various packages and, as a result, we have listed the average results under each file. These results are verified from different locations.

The most dangerous files to download are executable files that sport an .exe extension at the end of the filename. Clicking on these will run a program of some kind, and could therefore pose an active threat. Open a trusted website that contains downloadable files. Typically, websites offer a Download button or link that initiates a file download.

Test .xls or Microsoft Excel file with ease using this free service. You need not to create an excel file, enter dummy data probably in thousands, and then test to see whether it works fine while building an app. With an .xls file available for all sizes, you can just download straight away as per your requirement, and test it in seconds. Here you find .xls files available with size ranging from 10 to 50000 rows. So, enable a faster demo with .xls file rapid download.

Whether you have allocated a size in kb or mb for an excel file upload, just see which one suits the requirement. What makes this service unique is download is completely free when it comes to testing .xls or Microsoft Excel file. Testing your php, c#, or any other programming language code targeted towards xls file import functionality becomes much easier now with just one tap download. The dummy xls file contains enough bulk entries for use. All you need to do is hit the DOWNLOAD button, and get started.

I am using axios for basic http requests like GET and POST, and it works well. Now I need to be able to download Excel files too. Is this possible with axios? If so does anyone have some sample code? If not, what else can I use in a React application to do the same?

More documentation for URL.createObjectURL is available on MDN. It's critical to release the object with URL.revokeObjectURL to prevent a memory leak. In the function above, since we've already downloaded the file, we can immediately revoke the object.

This is actually even more complex when you want to download files using Axios and some means of security. To prevent anyone else from spending too much time in figuring this out, let me walk you through this.

When employing transport security, JavaScript executing within a browser can [by design] access only 6 of the HTTP headers actually sent by the HTTP server. If we would like the server to suggest a filename for the download, we must inform the browser that it is "OK" for JavaScript to be granted access to other headers where the suggested filename would be transported.

Browser (atleast chrome) will try to open the file if the download attribute is not set. If set, it will download the file. The name of the file will be the value of the last path param in cases where the url is not a blob.

will keep opening new tabs unnecessarily and user might have to make allow popups for work this code, what if user want to download multiple files at the same time so go with solution first or if not try for other solutions also

If you would like to download this data instantly and for free, just click the download button below. The download will be in the form of a zipped file (.zip) and include both a Microsoft Excel (.xlsx) and CSV file version of the raw data.

Another possible place to get large amounts of random text data for compression testing would be data dump sites such as Wiki or even Stack ExchangeI've alse found this blog post that lists 10 open source places to get complex text data for analytics testing.There are a lot of online resources for creating large text files of arbitrary or specific sizes, such as this Lorem Ipsum Generator which I have used for script development, but I've learned that these sources are no good for compression testing because the words tend to be limited and repetitive. Consequently, these files will compress considerably more than natural text would.

You can see a screen shot of each dataset, and a list of the columns it contains, with a brief description. Then, to get started, you can download sample Excel file with data for your training sessions.

You can use a CSV (comma-separated values) file to import products into your Shopify store, and to export products from your store. When you use a CSV file, you can import or export a large number of products and their details at same time. This can be helpful if you want to exchange product information between Shopify and other platforms.

Please be aware that downloading these files will count towards your download usage allowances imposed by your broadband provider and the large files may use up a large proportion of this if you only have a small allowance (1GB - 3GB for example). We suggest only testing the large files if you have a connection speed faster than 10 Mbps.

NOTE: We provide these download files primarily for UK broadband users; although we do not prohibit their use by others, we do not allow scripted/automated download of these files. Our systems routinely block repetitive attempts which we believe are automated or abusive. If you get an 'unauthorised' error message, you can contact us (please include your IP address when contacting us).

The table below shows scaled JPEG (on the left) and WebP images (on the right)side-by-side for comparison. Since browsers exist that support WebP natively,we no longer place WebP images in a PNG container as we did at launch. Imagefile sizes are exact. Clicking on the JPEG and WebP thumbnails will open thelarge images in a new tab

Test Files are the files that are used to test the download speed of the internet that you are using. Apart from that, these files can also be used to check the quality of the bandwidth and the limit they are providing. In simple terms, these are the files that are hosted on the high-speed server and through which we can easily our internet speed by downloading them.

Moreover, you can also use these files for testing applications and some users also use them to consume their bandwidth. By downloading these huge files you can easily compare or benchmark your internet service.

Also, these files are available from different locations like USA, India, Australia, Germany, and more with high-speed download servers. Below we have listed multiple test files in different sizes and formats.

From here, you can easily download large test files that are available in Gig or Gigabyte sizes varying from 100GB to 1GB. Some users also search for 1TB file size but for that, I would recommend you should have at least a 1Gbps connection otherwise this large file will take so long. Also, before testing these files I would suggest you do a speed test and check you are getting the right speed.

In this section, we have added the small test files in MB or megabyte sizes that vary from 500MB to 5MB. And if you searching for a 1000MB file then you can download the above file of 1GB instead of that. Also, all the links and sample files shared are totally virus free.

Using these files for testing purposes is very easy, just you have to click on the download link of your desired file size and then check how much time a file takes to get downloaded completely. Generally, all these are accessed through IPv6 but sometimes you may also get IPv4 with other options like HTTPS or non-HTTPS ( HTTP ).

All these test files are stored on very fast servers without any download limit so that you can easily get the file saved without any issues. Also, these files may not look for the bandwidth but I would suggest you to at least check one time if your ISP has added any size limit while downloading the files. Furthermore, I would recommend you to only use large files when you have a connection of at least 100Mbps and if you have some lower speed then go for small test files.
