Files (images, audio, PDFs, any binary data) are stored next to your app and served from a CDN. An object refers to a file through a `File` field; the file itself is uploaded once and can be referenced by many objects.

## Upload

```javascript
const input = document.querySelector('#avatar');            // <input type="file">
const file = new Parse.File('avatar.jpg', input.files[0]);
await file.save();

const user = Parse.User.current();
user.set('avatar', file);
await user.save();

console.log(file.url());   // https://<id>.files-sashido.cloud/...
```

From other sources: `new Parse.File(name, { base64: '...' })`, or bytes on Node.js. Every SDK has the same `File` type: see Parse's guides for [iOS](https://docs.parseplatform.org/ios/guide/#files), [Android](https://docs.parseplatform.org/android/guide/#files) and [REST](https://docs.parseplatform.org/rest/guide/#files).

Parse adds a unique prefix to each file's name, so two uploads of `avatar.jpg` never overwrite each other.

## Serve

`file.url()` is the file's address on the CDN (**App Settings › Security & Keys › Files URL (CDN)**). Show it in an `<img>`, link to it, or hand it to a video player.

File URLs are public: anyone with the URL can download the file. The file name's random prefix makes URLs hard to guess, but for private documents, don't hand out the URL: serve them through a cloud function that checks the user first.

## Limits and pricing

- Up to **20 MB** per file. For larger files, contact support.
- Storage and data transfer are billed by use: see [pricing](https://www.sashido.io/en/pricing/north-america-region).
- Compress images and videos on the client before uploading: it saves storage, transfer and your users' time.

## Delete

Deleting an object doesn't delete the files it refers to (another object may use them). Delete a file with the master key, typically in an `afterDelete` trigger:

```javascript
Parse.Cloud.afterDelete('Photo', async (request) => {
  const file = request.object.get('image');
  if (file) {
    await file.destroy({ useMasterKey: true });
  }
});
```

## From scripts and AI assistants

`POST files/<name>` through the [Management API's Parse proxy](/en/docs/developers/api#your-apps-data-the-parse-proxy) uploads up to 10 MB with an access token. Through [MCP](/en/docs/developers/mcp), `upload_file` takes the content directly; the local server can also upload from a path or a URL.
