How to Prepare an Image for NFT Minting

If you want to turn your image into an NFT, beauty and uniqueness are important, but there are other key factors you must consider. Here's a full guide including technical requirements and best practices.

1. Resolution and Quality

• Recommended Resolution (OpenSea & Major Marketplaces):
  • Standard: 2000 × 2000 px or higher (square format preferred).
  • Large Displays: 3000 × 3000 px (ideal for high-end collectors).
• DPI: 72 DPI (standard for digital/web display).
• Color Mode: RGB (not CMYK).

2. File Formats & Size

• Supported formats: PNG, JPEG, GIF (static); MP4/WebM (animated).
• Maximum file size (OpenSea): 100 MB (most NFTs are under 10 MB for fast loading).

3. Ownership and Rights

• You must own full rights to the artwork or have permission from the creator.
• Avoid using copyrighted images or logos without authorization.

4. Metadata and Rarity

• Add title, description, properties, and traits to define uniqueness.
• Traits (e.g., "Background: Gold") help create rarity in collections.

5. Utility (Optional)

• Add value by offering perks: community access, bonus files, unlockable content, or in-game utility.

6. Blockchain Choice

• Ethereum: Most popular, but higher gas fees.
• Polygon: Cheaper, eco-friendly, OpenSea supported.
• Solana, Tezos: Fast, low-cost alternatives.

7. Edition Type

• 1/1 (One of One): A single unique NFT (like fine art).
• Limited Editions: Fixed small number of copies.
• Generative Collections: Large sets with algorithmic traits.

8. Branding & Storytelling

• Explain the inspiration or meaning behind your art in the description.

9. Promotion

• Promote on Twitter, Discord, Instagram, Reddit.
• Collaborate with artists, influencers, and NFT communities.
