At times, you may want to sell a digital product such as an image, audio file, or e-book. This can be easily accomplished in OpenCart. To offer a downloadable product, you'll first have to upload the file within OpenCart and then you'll need to link the file to a product. 

Important! Remember to uncheck the "Requires Shipping" checkbox or your customers will be charged shipping fees by mistake.

Uploading Your Digital Product

  1. Log into your OpenCart Dashboard
  2. Go to Catalog > Downloads
  3. Click “Insert” in the upper right corner
  4. opencart_digital_1

  5. Fill in the fields with a download name, Select the file to upload on your local computer, and type in the number of downloads allowed per user purchase
  6. opencart_digital_2

  7. Click “Save

Linking the download file to a product

  1. Log into your OpenCart Dashboard
  2. Go to Products
  3. Click “Insert” to create a new product or click “Edit” next to an existing product
  4. Click on the “links” tab
  5. Scroll towards the bottom of the page, go to the “Downloads” section and select the file you want to be made available on this product
  6. opencart_digital_3

  7. While still editing this product, click on the “Data” tab and scroll down to the section called “Weight”. Enter a weight of “0” (zero) in the field. This tells OpenCart it is a downloadable product
  8. Click on “Save” in the upper right corner

Trial products

If you want to offer your customers a trial of your software, there are a few different routes you can take.


As OpenCart cannot simply modify your downloadable products to offer some sort of trial, you will need to have one of the following to offer as the trial:

  • Two versions of your software; One that is fully unlocked that you will sell and one that only works as a trial
  • Offer a single product for download and sell the license key either within the software, or through another product on your site

Adding the trial product

If you are offering the trial product as a secondary item in your store, you can simply add it just as you would any other downloadable product, and sent the price to be free.

You could also place some sort of additional download link to the product within your main product page which would allow you to have a single page for both the trial product as well as the paid product.

If you need further assistance please feel free to ask a question in our support center website.

Hi Tim, Good tutorial but you need to comment that when creating a download only product you need to remember to uncheck the "requires shipping" checkbox.
I forgot and people were being charged for shipping at checkout - lost me a few sales...

Hello, thanks for your tutorials but this is doesn't work for CD and digital download which mean unique download for each order from the same product, as currently when you make a downloadable product all customer order it can see it in there account and if you put multiple CD key they will receive all of them.

I appreciate if you support me in editing the php file or do it by VQmod.

Thank you for your comment elprince !

Sorry for the CD and Digital downloads are not working for you. You can edit the php.ini in your public_html to change any settings. Please see the following link on this.

How to update your local php settings

You will need to make the php.ini recursive as well. Please see the following.

How can I make my php.ini file recursive ?

If you need assistance doing this, please contact tech support. This is a public forum and you cannot put your personal information in here. Tech support will be able to help you with this.

Hey. After I select the links tab and scroll down to the download field, there is only a blank field with no selection possible. The requires shipping field is also turned to "No". Any help here is much appreciated!

Hello BettyBoop,

I am not aware of the max download limit, however I have seen as many as 12. If you need more, you can always add some as a zip file.

Kindest Regards,

Any file type is supported, however, typically it is provided in a zip file. Once the purchase has been completed on the site, the customer will be provider a download link.

With downloaded products is there anyway to tell if they have actually downloaded it and not just purchased. I'm running into an issue where they claim they have not downloaded.

Ideas anyone?

Hello Insiyah,

Thank you for contacting us. When you set the "Total Downloads Allowed" (Step 4 of the "Uploading Your Digital Product" section above), it should make the file available until it has been downloaded.

Meaning if they are not able to download it, it most likely completed already.

It is possible they are having a problem with their computer, such as hardware, or a virus, bug, etc.

Also, it could be a connection problem, for example their network may be inconsistent, causing issues. Having them perform a Ping/Tracert to your website may help troubleshoot this.

Have you tried to replicate the problem as a customer? For example, using the same browser they are using, and trying to checkout and download the file?

Thank you,

Thanks for the response. I have tried to duplicate it, and I don't have any problems. It maybe some confusion the way my site is set up. I assumed what you said if it shows complete, it's complete. 

Thanks again.

I've followed these steps but when I get to product-link-downloads there is nothing in the list to choose from :( The downloadable product clearly shows in downloads just not in this list. What now?

Hello Christine,

Sorry for the problem with the downloads. In order for us to see what's happening we need a little more information. Can you please provide us a URL? Also, a URL and extensions/modules that you may have loaded may also give us an idea of how your current OpenCart installation is running.

Please provide some additional information and we'd be happy to help.

In the newest version of OpenCart, hover over the Settings and click on Settings. Then go to the Server tab. Here, you will see a bix with allowed file extensions in which you can then add zip to the list.

Thank you for the comment. However I have the Turkish version of v2.0.1.1 and no such settings-> server  tab exists. There is a system tab  with -> shops ->design -> users -> localisation

and there is also a tools tab with -> uploads (there is nothing here) -> Backup/Restore  and -> Error logs

I am talking about the admin panel. There are no settings and server taba anywhere.

Strange dilemma. I have checked every tab an I couldn't find anything close.

The icon I am referring to is the same as the System section that you are referring to. The icon displays a cog wheel. Based on what you have provided me, it seems that Settings may be replaced with Shops in your translation of OpenCart.

I am getting an undefined error message when I try to upload file about 17+ MBs.

I loaded a file which was around 2MBs without any errors. So I changed the Max File upload size to 999M (that is what is written in the php.ini file now) but I still get the message at around 2-3 minutes after upload starts.

Very Starnge!! Any ideas??

Could you provide us with the specific error?

Also, you may need to set your php.ini file as recursive to take full effect across all scripts.

The php.ini file is at  /domains/  

I think the userpanel type is  a bit different. I found my username but I am not sure how to arrange the

suPHP_ConfigPath /home/username/public_html

code according to the new panel.

Thank you again for your answer. I will be expecting your answer to this one as well.

Hello ASKural,

The 'suPHP_ConfigPath /home/username/public_html' is for our servers. It is simply a path to where the php.ini file is. You will need to have the su_PHP module installed and running for this to take effect. You may need to contact your hosting provider to see if they have that on their systems.

Hi Alex,

By default, after the customer were to purchase the downloadable product, it would show up in the customers account section on your website once they login.

I am new to Opencart.Feeling diffcult to do a task.I need your help on the below task.Please help me out.

Instead of receving e-mail with Voucher template after purchasing product,Voucher should be downloadable

Users can download the voucher using a chosen voucher template (Happy Birthday or something)

The vouchers are for the service items in the menu page (the items and prices are listed in the menu page).


If they choose 1 service(ex:Nail Treatment) item from the menu  it’s the same  price($25) as per the menu


But,If they choose 2 service items they get a 5% off from the total of the 2 items they choose(then its $25x2 minus 5%)


So the value of the voucher depends on what item they choose from the menu

Then they can download the voucher using a chosen design (Happy Birthday or something)

Hello Sinu,

Sorry if you're trying to use Vouchers and it's not matching up with how you want it to function. Unfortunately, if you want the vouchers want to be downloadable, you will need to have a developer custom program a solution for you, or find an extension that can do this for you. Apologies that we can't provide a direct solution for your request.

In the Downloads field, you must start typing in the name of the item and then it should show in the field for you to select. Did you give that a try?

Hello Sutani,

You can set the max upload parameter in a copy of the php.ini file in your account. Check out Increase the max file upload size for further instructions. If you have any further questions or comments, please let us know.
