upload files to pinate browser only
To upload files directly through the Pinata Web App browser interface, log in to your account, navigate to the Files page, click the Add Files button, select either File or Folder, choose the item from your computer, and confirm the upload.
Upload Steps
- Open Pinata and sign in.
- Go to the Files dashboard.
- Click Add Files.
- Pick File or Folder.
- Select your item and confirm.
If you meant uploading files using code directly from a browser frontend (instead of the web dashboard) or need help with API keys/JWT configuration, let me know!

browser only small code esm module
To upload files to Pinata directly from a browser environment using a lightweight ESM module, use the code below.
This method requires no bundler (like Webpack or Vite) and fetches the official Pinata SDK directly from a CDN.
Complete Browser Code (HTML + ESM)
Save this code as an
.html file and open it directly in your browser.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Pinata Browser Upload</title>
</head>
<body>
<input type="file" id="fileInput" />
<button id="uploadBtn">Upload to Pinata</button>
<script type="module">
// Import Pinata directly from a CDN
import { PinataSDK } from "https://esm.sh";
// Initialize with your JWT (Use restrictions in production!)
const pinata = new PinataSDK({
pinataJwt: "YOUR_PINATA_JWT_HERE",
pinataGateway: "example-gateway.mypinata.cloud"
});
document.getElementById('uploadBtn').addEventListener('click', async () => {
const fileInput = document.getElementById('fileInput');
if (fileInput.files.length === 0) return alert('Select a file first');
const file = fileInput.files[0];
try {
// Upload file object directly
const upload = await pinata.upload.file(file);
console.log("Success! CID:", upload.cid);
alert("Upload successful! CID: " + upload.cid);
} catch (error) {
console.error("Upload failed:", error);
}
});
</script>
</body>
</html>
Use code with caution.
Security Warning
- Exposed JWT: Placing your API Key or JWT directly in client-side browser code exposes it to anyone who inspects the page.
- Production Fix: For public web apps, generate short-lived scoped JWTs on a backend server, or use a backend proxy to handle the upload.
💡 If you want, I can show you how to generate a temporary, scoped JWT on a server so users can upload files securely without stealing your main keys. Would you like to see that?
