Imagine losing access to a file because the server hosting it shut down. That’s what happens every day on the traditional web. URLs break. Servers crash. Websites disappear. But what if your files could live on thousands of computers at once - and never vanish, even if one of them goes offline? That’s the promise of IPFS.
What IPFS Actually Is
IPFS stands for InterPlanetary File System. It’s not a website. It’s not an app. It’s a protocol - a set of rules that lets computers share files without relying on central servers. Think of it like BitTorrent, but for everything on the web, not just movies or software. Instead of asking, "Where is this file?" - like you do with a URL - IPFS asks, "What does this file look like?"
Every file you add to IPFS gets a unique fingerprint called a Content Identifier, or CID. This CID isn’t based on where the file is stored. It’s based on the file’s exact content. If you change even one letter, the CID changes completely. That means if you download a file from IPFS, you can be 100% sure it hasn’t been tampered with. No middleman needed. No trust required.
How IPFS Finds and Shares Files
When you upload a file to IPFS, it doesn’t go to one server. It gets split into small chunks - usually 256 KB each. Each chunk gets its own hash. Then those hashes are linked together in a structure called a Merkle DAG. This is what makes IPFS different from regular file systems. It’s not a folder tree. It’s a web of linked data.
Let’s say you upload a photo. IPFS breaks it into 5 chunks. Each chunk gets a CID like QmXoypizjW3WknFiJnKLwHCnL72vedxjQkDDP1mXWo6uco. The system then creates one master CID for the whole photo. You share that master CID. Anyone with IPFS can request it. Their computer asks the network: "Who has QmXoypizjW3WknFiJnKLwHCnL72vedxjQkDDP1mXWo6uco?"
Nodes - computers running IPFS - check if they have any of the chunks. If they do, they send them over. The requester puts the chunks back together. No central server. No waiting for a slow cloud provider. If ten people have the same file, you can grab pieces from all ten at once. It’s faster. And if one node goes down? No problem. Another one has it.
Content-Addressing vs. Location-Addressing
Traditional web links are location-based. You type https://example.com/photo.jpg. That link points to a specific server in a specific place. If that server shuts down, the link dies. That’s called link rot. It’s everywhere. The Library of Congress estimates over half of links in academic papers break within ten years.
IPFS flips this. You don’t ask for a location. You ask for a hash. The hash is the file’s DNA. If the file changes, the hash changes. If you have the same file as someone else, you both have the same hash. That means IPFS automatically deduplicates files. If 1,000 people upload the same 10MB video, it only takes up 10MB of space across the whole network.
This also means you can’t "delete" a file from IPFS the way you delete from Google Drive. Once it’s on the network and someone has it, it stays. That’s why IPFS is used for archiving censored content. When governments block Wikipedia, people still access it through IPFS gateways using the original CID.
How IPFS Connects to Blockchain and Web3
Blockchains like Ethereum are great at storing small amounts of data - like who sent what to whom. But they’re terrible at storing large files. A single high-res image can cost hundreds of dollars to store on-chain.
That’s where IPFS comes in. NFTs, decentralized apps, and DAOs use IPFS to store the actual images, videos, or documents. The blockchain only holds the CID - a tiny pointer. So when you buy an NFT, you’re not buying the image. You’re buying a certificate that says: "This CID points to the real image, and it hasn’t been changed."
Companies like OpenSea and Pinata use IPFS to store NFT metadata. If the IPFS node storing your NFT’s image goes offline, the NFT still points to the same CID. Someone else in the network will eventually serve it. That’s permanence.
How to Use IPFS Right Now
You don’t need to be a coder to use IPFS. Here’s how:
- Go to ipfs.io and download the IPFS Desktop app. It’s free and works on Windows, Mac, and Linux.
- Install it and launch it. Your computer becomes a node.
- Drag a file into the app. Wait a few seconds. It gives you a CID.
- Copy that CID and share it. Anyone with IPFS can open it.
Don’t want to install anything? Use a public gateway. Just type https://ipfs.io/ipfs/[CID] into your browser. Replace [CID] with the hash you got. You’ll see the file. No app needed.
Pro tip: If you want your files to stay available long-term, use a pinning service like Pinata or Infura. These services keep your files alive on their nodes - even if your computer turns off.
Why IPFS Matters for the Future
The internet was built for speed, not resilience. Centralized servers are efficient - until they’re not. A single data center outage can take down major platforms. DDoS attacks target the same few points. Governments can shut down websites by blocking IPs.
IPFS removes those single points of failure. There’s no central company to sue. No server to shut down. No ISP to censor. If you can reach any node, you can get the content.
It’s not perfect. Files won’t stay online unless someone’s hosting them. That’s why pinning services exist. Speed can be slower if no nearby nodes have the file. But the system improves every day. More people run nodes. More gateways pop up. More apps build on it.
IPFS isn’t replacing the web tomorrow. But it’s building the foundation for a web that can’t be turned off. A web where your photos, your documents, your art - they belong to you, not a corporation. And they’ll still be there, even if the servers go dark.
IPFS vs. Traditional Cloud Storage
| Feature | IPFS | Traditional Cloud (AWS, Google Drive) |
|---|---|---|
| Storage Model | Distributed, peer-to-peer | Centralized servers |
| File Addressing | Content-based (CID) | Location-based (URL) |
| Data Integrity | Cryptographically verified | Depends on provider |
| File Deletion | Cannot be fully deleted | Can be deleted by owner or admin |
| Availability | Depends on nodes hosting content | Guaranteed by provider |
| Censorship Resistance | High - no central control | Low - provider can block |
| Cost to Upload | Free (if you host) | Often paid |
Common Misconceptions
- "IPFS is a blockchain." No. It’s a file system. It works alongside blockchains but doesn’t store transactions.
- "IPFS is slow." Sometimes. If no one has your file nearby, it takes longer. But once it’s popular, it’s faster than any cloud.
- "IPFS is only for tech people." False. You can use it with one click via gateways. Millions of users access IPFS content daily without knowing it.
- "If I upload something, it’s public forever." Not exactly. If no one pins it, it may disappear over time. But if even one person keeps it, it lives.
Is IPFS free to use?
Yes. You can download the IPFS software for free and start sharing files immediately. Public gateways let you access files without installing anything. However, if you want your files to stay available long-term, you may pay a pinning service like Pinata or Infura to host them on their reliable nodes.
Can I delete a file from IPFS?
You can’t delete it from the entire network. Once a file is uploaded and someone else has it, it stays. But you can stop hosting it on your own node. If no one else is pinning it, it will eventually become unavailable. That’s why pinning services exist - to ensure permanence.
How is IPFS different from BitTorrent?
BitTorrent creates separate swarms for each file. IPFS creates one global network. If two people upload the same file, they’re sharing the same chunks. If you download a file from someone, you’re also helping others who want the same file. It’s a unified system, not dozens of isolated swarms.
Do I need to run a node to use IPFS?
No. You can use public gateways like ipfs.io or gateway.pinata.cloud to view files without installing anything. But if you want to host files and help the network stay fast and reliable, running a node helps everyone - including you.
Is IPFS secure?
Yes, in terms of data integrity. Every file is cryptographically signed by its hash. If someone alters the file, the CID changes. You’ll know it’s not the original. But IPFS doesn’t encrypt files by default. If you upload private data, make sure to encrypt it first - just like you would with any public cloud.
What happens if no one has my file anymore?
It becomes unreachable. That’s why pinning is important. If you upload something important, pay a pinning service to keep it alive. Or ask a friend to download and keep it. IPFS doesn’t guarantee storage - it just makes it possible to share. The responsibility to keep files alive falls to users.
What’s Next for IPFS
IPFS is already powering decentralized versions of Wikipedia, news sites, and NFT marketplaces. In 2025, more browsers are starting to support native IPFS links. Wallets like Phantom and MetaMask now let you view IPFS-hosted NFTs directly. Governments and libraries are exploring it for long-term digital preservation.
It’s not the only solution. Filecoin builds on IPFS to create a marketplace for storage. Arweave offers permanent storage for a one-time fee. But IPFS remains the most widely adopted protocol for decentralized file sharing.
If you care about digital permanence, censorship resistance, or true ownership of your data - IPFS isn’t just a tool. It’s the first step toward a web that can’t be controlled by anyone.

November 29, 2025 AT 07:14Guys let me explain this properly. IPFS is not just about files. It's about identity. When you upload something, you're not just storing data-you're embedding truth into the fabric of the network. Every CID is a fingerprint of reality. If your file gets corrupted, the CID changes-so you know immediately. No middlemen, no lies. That’s why governments hate it. They can’t control what they can’t delete. And yes, I’ve used it to access banned Wikipedia pages during the 2020 internet shutdowns in India. It saved my research. This isn’t tech. This is survival.

November 29, 2025 AT 10:34Love how this explains content addressing vs location. So simple yet so powerful. The web was built on fragile foundations and we’re just now realizing it.

November 29, 2025 AT 13:46I’ve been running an IPFS node for 2 years now. Not because I’m some tech bro. Just because I don’t trust corporations to keep my photos alive. My daughter’s first steps? Still there. No cloud account needed. No subscription. Just… there. Quietly. Always.
George Kakosouris
November 30, 2025 AT 09:06Let’s be real-IPFS is a technical unicorn. It sounds great on paper but in practice, it’s a latency nightmare unless you’re in a major node hub. And don’t even get me started on the ‘pinning economy’-it’s just centralized storage with a DAO veneer. This isn’t decentralization. It’s distributed centralization with extra steps.
Brian Bernfeld
November 30, 2025 AT 23:26As someone who’s helped archive protest footage from 6 different countries, IPFS isn’t just a tool-it’s a lifeline. When the regime blocks everything, people still access the footage through gateways. No VPNs. No tricks. Just a hash. That’s power. And yeah, I’ve taught high schoolers in rural Mexico how to use it. No code needed. Just copy-paste. This is how knowledge survives tyranny.
stephen bullard
December 2, 2025 AT 22:34Think about it-what if every website, every photo, every song could live forever? Not because someone paid for hosting, but because enough people cared to keep it alive. That’s what IPFS gives us. Not perfection. Not speed. But possibility. And maybe that’s enough.

December 4, 2025 AT 01:45Why pay for pinning? Just ask a friend. Free. Easy. Done.
Abby cant tell ya
December 4, 2025 AT 04:59So let me get this straight-now I have to trust strangers on the internet to keep my files? What’s next? Asking randoms to babysit my hard drive? This is why I stick with Google. At least they’re predictable.
Mark Adelmann
December 5, 2025 AT 22:58Used IPFS to share my grandma’s recipe book after she passed. No cloud. No login. Just a link. My cousin in Canada opened it yesterday. She cried. That’s the magic. Not the tech. The human part.
Vance Ashby
December 6, 2025 AT 23:01IPFS = cool. But honestly? If your file disappears because you turned off your laptop, that’s on you. Also, I just found out my NFT’s image is hosted on IPFS… and my node went down for a week. Felt like losing a pet. 😔

December 7, 2025 AT 19:50ipfs is the future but i keep typos in my cids and now my cat video is gone forever. pls help. i think i typed qm instead of qm. or was it the other way? i dont remember. help.
Tony spart
December 7, 2025 AT 20:37This is why America needs to ban IPFS. It’s a tool for anarchists and foreign agents. Who needs a web that can’t be controlled? We need order. Not some peer-to-peer chaos.
Vaibhav Jaiswal
December 9, 2025 AT 05:40I use IPFS to share my music. No label. No platform. Just me and my fans. One guy in Nigeria downloaded my album and now he hosts it for 200 others. That’s community. Not capitalism.

December 11, 2025 AT 00:05From a systems theory perspective, IPFS represents a paradigmatic shift from hierarchical, server-centric topologies to emergent, content-distributed networks. The Merkle DAG structure enables non-repudiable provenance at scale, fundamentally decoupling identity from location-a necessary evolution for post-protocol digital sovereignty.
Brian Bernfeld
December 11, 2025 AT 20:13That’s why pinning services aren’t a flaw-they’re a social contract. Like libraries. Someone has to keep the books alive. If you want your data to last, you owe it to the network to help. It’s not tech. It’s responsibility.

December 12, 2025 AT 14:06So now we’re glorifying file-sharing as a moral crusade? What’s next? Calling pirates saints? This is just piracy with a blockchain halo.
jeff aza
December 14, 2025 AT 06:18IPFS is ‘decentralized’… until you realize 80% of all pins are hosted by just 3 companies (Pinata, Infura, Consensys). That’s not decentralization-that’s oligopoly with extra steps. Also, the CID system is cryptographically sound, but the UX is a nightmare for non-devs. Why should I need to understand hashes to share a photo? This isn’t progress. It’s over-engineered.
Ben Costlee
December 14, 2025 AT 23:47I used to think this was just for techies. Then my sister uploaded her wedding photos. She didn’t know what a CID was. She just clicked ‘share’. Two years later, her mom in another country opened it on her phone-no app, no login. Just a link. She cried. That’s not tech. That’s love. And it’s still there. No company owns it. No server broke it. Just… there. Quietly. Forever.
