Introduction: Beyond Simple Text Lookups
When Ethereum Name Service (ENS) launched, its primary purpose was to replace long hexadecimal wallet addresses with human-readable names like “alice.eth.” For years, this simple text-resolution system served the crypto community well. However, as Web3 identity expands, users crave richer, more expressive profiles—enter ENS domain multimedia support.
Multimedia support allows ENS domain holders to attach images, 3D avatars, NFT thumbnails, audio clips, and video previews directly to their .eth names. This turns a static text resolver into a dynamic, branded digital identity. Whether you are a creator showcasing your latest NFT drop or a business presenting a professional avatar, multimedia fields unlock new possibilities.
In this beginner’s guide, we’ll walk through what multimedia support means, how to set it up, and why it matters for your Web3 presence. You’ll learn the exact fields, tools, and best practices to make your ENS domain stand out. For a deeper dive into real-world use cases, check out Ens Domain User Stories — a collection of how enthusiasts are already leveraging these features.
1. The Core Components: Text Records vs. Multimedia Records
ENS domains rely on “records” – pieces of data that tell applications what to display when someone resolves your name. Text records include fields like email, URL, avatar, and description. Multimedia support extends these records to handle binary files, embedded media, and rich metadata.
Here’s a breakdown of standard text records vs. multimedia-enabled records:
- Text records (legacy): avatar (URL only), url, email, description, keywords.
- Multimedia records (new): NFT image (direct asset URI), 3D model (glTF format), video, audio, PDF attachment.
- Supporting metadata: Content types (e.g., image/png, video/webm), alt text, license info.
- Profile integration: Social preview graphics, animated signing requests, VR-ready data.
The shift from text-only to multimedia makes your ENS domain a portable digital persona that galleries, wallets, and metaverses can interpret richly. For example, when someone sends ETH to your .eth name, the wallet can show your NFT avatar as a preview.

2. How to Set Up Multimedia Fields: Step-by-Step Guide
Setting up multimedia support requires a compatible ENS manager, such as the official ENS app (app.ens.domains) or third-party dashboards like V3ENS. You will store media assets on a decentralized storage network (IPFS, Arweave, or a direct data URI for small items).
Step 1 – Prepare your media assets
Create or source an image (PNG/WebP), a vector logo (SVG), a short video clip (MP4/WebM), or a 3D model (glTF). Keep file sizes under 10 MB for smooth loading. Upload to IPFS via Pinata, NFT.Storage, or a personal node. Set a permanent IPFS CID.
Step 2 – Access your domain records
Open the ENS manager, log in with your wallet, and select your domain. Navigate to the “Records” tab. Look for fields labeled “avatar,” “com.ens.images.left” (for wearable displays), or “video”.
Step 3 – Fill in multimedia fields
- For an avatar NFT: enter the IPFS URI of your image, or an EIP-1155 token ID reference.
- For a video: paste the IPFS URI with a mime type suffix (e.g., ipfs://
?mime-type=video/mp4). - For 3D model: use a glTF file hosted on IPFS, updated via the “model” text key.
- Add an “alt” key (e.g., “avatar_alt”) describing content for screen readers.
Step 4 – Save and test
Confirm the transaction onchain. Then use a resolver page (like “ens.vision” or the official ENS viewer) to see if the media loads correctly. This may take a few minutes due to IPFS propagation.
3. Supported Media Types and Practical Use Cases
Understanding which media types are natively supported helps you design your ENS personality. The latest resolvers accept the following formats:
- Images: PNG, JPEG, WebP, GIF, SVG (with limits).
- Video: MP4, WebM, OGV – up to 60 seconds usually.
- Audio: MP3, OGG, FLAC – for NFT music or voicenotes.
- 3D models: glTF/glb – ideal for metaverse avatars.
- Documents: PDF, Markdown – for onchain résumés.
- Metadata sets: WalletConnect v2 and OpenSea Pro enrich profile cards.
Real-world examples illustrate the power of multimedia ENS domains:
A digital artist registered “painter.eth” and attached a high-res PNG of their current collection as avatar, plus a direct IPFS link to a time-lapse video of their creation process. When collectors look up the ENS name in OpenSea, they see both image and video data in the profile card.
A DAO registered “producthub.eth” and linked a 3D model of their virtual lobby, allowing visitors using Spatial or Decentraland to teleport directly to the DAO’s headquarters scene. This bridges ENS with spatial web experiences.

4. Security and Size Considerations
Adding multimedia to ENS domains is exciting but raises practical concerns for beginners. First, storage costs: storing binary data directly on Ethereum is prohibitively expensive, so multimedia assets always reside offchain (IPFS, Arweave, or Web2 CDN tied to a DID).
Second, provenance matters. If you attach a video from a censorable URL (like an AWS S3 bucket), the multimedia record may break if the link changes. Always pin your files to decentralized, provider-agnostic storage. Third, keep animation loops efficient – giant files drive up nterface loading times and may not load in lightweight wallets.
Additional security tips:
- Use IPFS cluster or Filecoin for redundancy.
- Set caching headers via IPFS Gateway service.
- Test in multiple resolvers (argent, rainbow, coinbase wallet).
- For subdomains managing video events, refer to logs compiled in Ens Subdomain Events for typical size limits and failures.
Size limits vary by resolver: most allow up to 256KB per text record but read URI-linked files of any size from external gateways. Avoid heavy pages – keep total profile weight under 5MB for mobile compatibility. Auditing your setup ensures your ENS identity remains graceful even if gateways throttle.
5. The Future of ENS Multimedia Support: 2025 and Beyond
Currently, the ENS team is working on a new “Records Schema” version 2 (RSv2) that natively supports subkeys for multimedia (e.g., “com.ens.video.overview.mp4”). This improvement will formalize how wallets request animated vs. static media, and will integrate with the new metadata handler for ERC-1271 signatures.
We expect three major trends:
- Dynamic NFT profiles where tokens update visual data in ENS automatically.
- Audio routing – a .eth name could resolve to a streaming track if you are an artist.
- Real-time social data likes and comments rendered as sparklines inside profile lookups.
For builders, a growing number of SDKs offer ready components to display ENS media. RainbowKit and ConnectKit already show thumbnail images. Next year, video will be standard too. If you are an event organizer tracking how your ENS subdomain gallery performs, community-compiled analytics in Ens Subdomain Events provide year-over-year growth data.
As gas-efficient aggregators (like CCIP-Read, or ENS Gateway extensibility) bring offchain multimedia to onchain apps instantly, feeling comfortable with these fields now gives you a head start. The richer your profile, the more likely strangers trust your transaction.
Conclusion: Your Next Steps
ENS domain multimedia support transforms a plain alias into a lively digital business card that any Web3 interface can parse. From setting your avatar NFT to embedding a project trailer, every field adds meaning and professionalism.
To get started immediately:
- Choose a multimedia asset (image, video, or 3D).
- Upload it to IPFS and copy the CID.
- Open your ENS manager, go to Records, and add the correct text key (e.g. “token=” for an NFT thumbnail or “avatar” for a profile picture).
- Test it on app.ens.domains or a compatible interface.
The shift is irreversible: plain text ENS names will soon feel incomplete. By adding multimedia now, you make your domain discoverable, trustable, and beautiful across dozens of dApps.
