Free NFT Metadata Viewer

The NFT Metadata Viewer is a free online tool that view nft metadata by contract address and token id. fetches token uri via json-rpc, resolves ipfs links, and displays image, traits, and collection info.. It runs entirely in your browser with no installation or sign-up needed.

Ethereum, Polygon, and BSC using public Ankr RPC endpoints.

The tool calls tokenURI() on the contract via eth_call, then fetches the metadata JSON (including IPFS links via public gateway).

Yes, completely free.

Yes, the NFT Metadata Viewer is fully responsive and works on smartphones and tablets. You can use it on any device with a modern web browser -- no app download required.

No account or registration is needed. Simply open the NFT Metadata Viewer in your browser and start using it immediately. There are no sign-up walls or usage restrictions.

Simply enter your input in the provided field, adjust any settings to your preference, and the tool will process it instantly. You can then copy the result to your clipboard or download it.

The NFT Metadata Viewer works in all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. For the best experience, use the latest version of your preferred browser.

Marketplaces like OpenSea display cached, indexed data that they refresh on their own schedule, so a recent metadata update, a re-pin, or a reveal can leave their listing stale for hours or days. This viewer reads closer to the source of truth: it calls the contract's tokenURI directly (or pulls fresh OpenSea API data for Ethereum) and then fetches the JSON that URI points to, showing you exactly what the blockchain pointer resolves to right now. If the traits here are correct but the marketplace shows old values, the marketplace cache simply hasn't caught up. If they differ in the other direction, the on-chain metadata may have changed or was never properly pinned. Paste the contract address and token ID to compare the live metadata against what any marketplace is showing.

That message means the viewer read the metadata but could not load the artwork the image field points to. The most common causes are a broken or moved image URL, an IPFS gateway that timed out, or metadata that was never properly pinned, so the link resolves to nothing. Because NFT images are often stored on IPFS, the tool automatically rewrites ipfs:// links into an https://ipfs.io/ipfs/ gateway URL that a browser can load, but if that gateway is slow or the content was unpinned, the image still fails. The raw token URI and JSON shown alongside the preview let you see the exact image link, so you can test it in another gateway or confirm the asset is genuinely missing. Look up the token here to see whether the image pointer itself is broken or just the gateway.

Lookups only work for contracts that implement the ERC-721 metadata extension, meaning they expose a standard tokenURI(uint256) function the viewer can call. A plain token contract, an ERC-20, or a non-standard collection without tokenURI returns nothing to decode, so no metadata appears. A second cause is the token ID itself: if that ID was never minted or has been burned, the contract has no URI to return. Finally, some metadata is hosted on IPFS or third-party servers that block cross-origin browser requests via CORS; in that case the token URI still displays but the JSON fails to load. When that happens, the block explorer link and raw URI give you a manual path to inspect the data. Enter a valid ERC-721 address and an existing token ID to get a clean result.

A large share of NFT metadata and artwork is stored on IPFS rather than a normal web server, and browsers cannot load a raw ipfs:// link directly. To solve this, the viewer automatically rewrites any ipfs:// reference into an https://ipfs.io/ipfs/ gateway URL, which is a standard web address a browser can fetch. It applies the same conversion to both the metadata JSON location and the image field inside that JSON, so artwork pinned to IPFS still renders in the preview. This is why you can paste a contract and token ID and see the image even when the underlying storage is decentralized. The original, unmodified token URI is still shown so you can see the true ipfs:// pointer. Look up any token to watch the IPFS link resolve into a viewable image and downloadable JSON.

A standard ERC-721 metadata JSON follows a predictable shape. The name and description give the token a human-readable identity, the image field holds a URL to the artwork (frequently an IPFS link), and the attributes array lists trait_type and value pairs that define rarity, such as background, eyes, or hat. Optional fields like external_url and animation_url point to a project page or an animated or 3D version of the asset. This viewer parses that JSON and renders each piece for you: the image as a preview, every attribute as a labelled trait badge, and the full raw JSON for inspection, plus a one-click button to download the complete file as a snapshot. Seeing the rendered output beside the raw data makes it easy to spot a missing image or a malformed trait. Enter a contract and token ID to see the full metadata broken down.
