​
What is Pinata?

Pinata provides private and public file solutions for developers, making it easy to upload a file in your app and retrieve it securely. Additionally, Pinata is the largest IPFS provider, helping countless developers scale their decentralized applications. Whether you need verifiable file storage or a peer to peer solution, Pinata has you covered.

​
Private Files

By using the SDK, uploading private files is just one line of code.

const { cid } = await pinata.upload.file(file)

Accessing private files is just as easy!

const signedUrl = await pinata.gateways.createSignedURL({
 	cid: cid, // CID from our upload
	expires: 30, // How many seconds the link is valid for
})

Be sure to follow the quickstart below to start using Pinata in your app!

​
IPFS Files

Using IPFS is just as easy, and only requires a few minor changes by using the IPFS SDK instead of the Files SDK.

import { PinataSDK } from "pinata-web3"

const upload = await pinata.upload.file(file)

const ipfsUrl = await pinata.gateways.convert(upload.IpfsHash)

Follow the IPFS quickstart for more info!
