IPFS aims to complement HTTP in order to build a better web for all of us.
HTTP downloads files from one server at a time — but peer-to-peer IPFS retrieves pieces from multiple nodes at once, enabling substantial bandwidth savings. IPFS makes it possible to efficiently distribute high volumes of data without duplication.
The average lifespan of a web page is 100 days before it's gone forever. The medium of our era shouldn't be this fragile. IPFS makes it simple to set up resilient networks for mirroring data, and thanks to content addressing, files stored using IPFS are automatically versioned.
The Internet has turbocharged innovation by being one of the great equalizers in human history — but increasing consolidation of control threatens that progress. IPFS stays true to the original vision of an open, flat web by delivering technology to make that vision a reality.
IPFS powers the creation of diversely resilient networks that enable persistent availability — with or without internet backbone connectivity. This means better connectivity for the developing world, during natural disasters, or just when you're on flaky coffee shop wi-fi.

The IPFS Desktop app offers menubar/tray shortcuts and an easy interface for adding, pinning, and sharing files — plus a full IPFS node ready for heavy-duty hosting and development. Great for developers and less experienced users alike.
Just want to use IPFS from your terminal? Follow these step-by-step instructions for getting up and running on the command line using the Go implementation of IPFS. Includes directions for Windows, macOS, and Linux.
Here's what happens when you add a file to IPFS — whether you're storing that file on your own local node or one operated by a pinning service or IPFS-enabled app.
When you add a file to IPFS, your file is split into smaller chunks, cryptographically hashed, and given a unique fingerprint called a content identifier (CID). This CID acts as a permanent record of your file as it exists at that point in time.
When other nodes look up your file, they ask their peer nodes who's storing the content referenced by the file's CID. When they view or download your file, they cache a copy — and become another provider of your content until their cache is cleared.
A node can pin content in order to keep (and provide) it forever, or discard content it hasn't used in a while to save space. This means each node in the network stores only content it is interested in, plus some indexing information that helps figure out which node is storing what.
If you add a new version of your file to IPFS, its cryptographic hash is different, and so it gets a new CID. This means files stored on IPFS are resistant to tampering and censorship — any changes to a file don't overwrite the original, and common chunks across files can be reused in order to minimize storage costs.
No matter what you do with the web, IPFS helps make it better today.
Storing archival data using IPFS enables deduplication, clustered persistence, and high performance — empowering you to store the world's information for future generations.
Providing large amounts of data to users? Storing on IPFS could help you slash bandwidth costs thanks to its use of secure, peer-to-peer content delivery.
If you're working with or distributing large datasets, storing that data using IPFS can help speed up performance and unlock decentralized archiving.
IPFS content addressing enables you to store large files off-chain and put immutable, permanent links in transactions — timestamping and securing content without having to put the data itself on-chain.
IPFS empowers creators to build and share on the decentralized web — whether that's delivering content free from intermediary control or minting NFTs that stand the test of time.
High-latency networks cause major obstacles for those with poor internet infrastructure. Peer-to-peer IPFS offers resilient access to data independent of latency or backbone connectivity.
