Bottom Line 

According to Crypto Potato, the launching of NFT collections has had a year-over-year increase of over 15k collections, and there are presently over 80k NFT collections in the NFT ecosystem. Thus, showing the relentless efforts of NFT creators and projects.   

However, NFT creators are facing a major challenge in their course of business: NFT creators can neither upload nor list hundreds or thousands of their NFTs for sale at once. It's high time this setback is permanently solved so there can be a greater level of productivity in the space.   

Can't upload multiple NFTs on Opensea?

These problems persist because a lot of NFT marketplaces like OpenSea don't currently support NFT bulk upload. As a result, NFT creators have to upload the collectibles one after the other, and this could last for days or perhaps weeks because one NFT collection can have up to 10,000 items.   

To solve this, NFT creators have two options: either they hire Developers to help them out or they use third-party solutions. But over time, they often opt for the latter because Developers often charge higher than the price of average bulk upload tools.   

To this end, we will take a look at the concept of NFT bulk upload and its benefits. Beyond that, we will thoroughly assess the current third-party solutions. Read on. 


What Is NFT Bulk Upload?

What Is NFT Bulk Upload?

Bulk upload refers to the process where NFT store owners can transfer NFTs en masse from wherever they were initially stored into an NFT marketplace's server and also list them for sale. 

NFT creators find this easier than the manual upload of their collectibles. To bulk upload, you'd need to take a few steps:

  • Keep all your collectibles in a single folder 
  • Write down each collectible's Metadata and other details in an excel file as you want them to appear 
  • Upload both the collectibles and Metadata to the third-party tool
  • The third-party tool sends everything to your NFT marketplace at once
  • The tool will also list all the NFTs, along with their details, for sale once on the marketplace 

What Are The Benefits of Uploading Multiple NFTs? 

This solution has two main benefits

1. Saves Time

NFT upload is usually carried one after the other, and this can take a lot of time which can be up to a week or even longer. But bulk upload NFT collection solutions free the creators from manual uploading which can be both stressful and overwhelming.   

In addition, bulk upload also helps founders of NFT projects to list their NFTs for sale at once instead of doing it one by one. Bulk upload can be done in a matter of minutes with only a few clicks. 

2. Removes Manual Error 

While it might be easy to manually upload a single NFT without any error, it would be a different case if there are thousands of NFTs to be uploaded. As an NFT creator, you are bound to mix-up the details of NFTs that are up to 10,000. 


But with an NFT bulk upload solution, the upload is automated and the chances of error are extremely low because the details of each NFT would have been thoroughly added in a spreadsheet.
