The NFT can be anything digital. From drawings to music, videos to regular animated GIFs, you can literally sell anything as an NFT as long as there is general demand. That’s why NFTs are so important in today’s market.
However, the most common and well-known file format that is certified as an NFT and easy to edit is the JPEG or PNG format of the image. For more information on starting a carrier with NFT generation, see How to generate an image-based NFT or how to convert an existing JPEG to an NFT.
Top 5 Ways to Convert a File To a NFT
1.Open Sea

Assuming you have selected the format you want to upload to the marketplace, here is a list of steps to help you become a creator and start your journey in OpenSea.
OpenSea allows you to upload both a single NFT collection or an entire NFT collection. According to most OpenSea developers, creating a collection is the most useful approach. Set up a collection site and upload items with the appropriate presentation via product images. Select the polygon blockchain as the default blockchain so that you can create NFTs for free.
2. Rarible

Raible is the second most popular NFT marketplace where you can create NFTs for free. Just go to rarible.com and connect your wallet. The easy-to-use interface of the website helps you create NFT pages as usual.
After setting up the page, all you have to do is find the “Free Mining” option and select the option to create an item. This will take you to a page where you can sign your free approval in your wallet and you’re done.
Converting JPEGs to NFTs or uploading art to an already physically existing NFT marketplace has the clear goal of creating more value from the product and the value that physical artwork provides. I have a complaint.
Therefore, you can get a unique sense of security by converting paintings to NFTs or selling JPEGs as NFTs. You need to know what kind of image you want to convey to the collector.
3. SuperRare

Super Rare is an exclusive cryptocurrency marketplace with a carefully selected selection of digital art created by prominent NFT artists and aspiring creators.
The SuperRare NFT Marketplace initially started as a centralized platform for scrutinizing artists through its core team, but in 2021, the platform launched the RARE Governance Token. This will begin the transition to a Decentralized Autonomous Organization (DAO) run by a community of creators. And collectors.
4. Foundation

Foundation was developed as a simple and unadorned way to bid on digital art. Sales are made through Ethereum. Since the market opened in early 2021, over $ 100 million of NFTs have been sold.
Artists are invited to the platform by the Foundation community and buyers only need an Ethereum-funded crypto wallet to initiate a purchase. If you’re looking for a quick and easy way to get started creating your own NFT, the Foundation is probably not the best place to get started, but the marketplace has a lot of artwork that you can browse in a simple format.
5. Nifty Gateway

Nifty Gateway has enabled the sale of the most popular digital artists such as Beeple and singer / musician Grimes. This is an art curation platform operated by Cryptographic Exchange Gemini (controlled by Winklevoss twins). Known as Nifties, NFTs are based on Ethereum.
Nifty Gateway is not only a carefully selected platform, but also hosts all purchased NFTs. This means that NFTs aren’t actually stored in your wallet, they are actually stored by Nifty Gateway and Gemini.
This may not work for NFT collectors who want more flexibility in investing in art, but buy and sell Nifty in fiat currencies (such as US dollars) without first buying cryptocurrencies.
Where Can you Explore your NFTs?
There are a lot of NFT explorers out there but the most eye catching one is from EGG.FI, you can simply login with your wallet address and explore your NFTs in a cool Web3 card.

Not that you can only explore your NFTs but you can even interact with other NFT holders. You will be able to like, comment, add to favorites or even bid on some NFTs that you like and want to have them on your NFT portfolio.
Final Thoughts
First, keep in mind that NFTs (Nonfungible Tokens) simply represent ownership of an asset. Before choosing an NFT marketplace, you first need to decide what type of digital asset you want to buy, sell, or create.
Almost all digital, written words, videos, video games, art, collectibles, etc. are on the blockchain (such as Ethereum (CRYPTO: ETH), the most common blockchain network NFT on which NFTs are built). It can be tokenized. Decreasing your interest is a good place to start.
Another consideration is the types of tokens supported by the marketplace. Some support different tokens. Others are closed marketplaces and use certain unique tokens. When opening an NFT Marketplace account, be sure to fund your blockchain wallet with the appropriate ciphers or tokens needed to participate in your site’s activities.
When you open an account, you will be asked to link your wallet to the NFT Marketplace. Also, check what security is set in the market and whether there have been any problems in the past.
