# Upload via custom path

Last updated Aug 24, 2026|Copy as Markdown|[View as Markdown](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/images/storage/upload-images/upload-custom-path/index.md)|[Agent setup](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/agent-setup/)

You can use a custom ID path to upload an image instead of the path automatically generated by Cloudflare Images’ Universal Unique Identifier (UUID).

Custom paths support:

* Up to 1,024 characters.
* Any number of subpaths.
* The [UTF-8 encoding standard ↗](https://en.wikipedia.org/wiki/UTF-8) for characters.

Note

Images with custom ID paths cannot be made private using [signed URL tokens](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/images/optimization/hosted-images/serve-private-images/). Additionally, when [serving images](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/images/optimization/hosted-images/serve-uploaded-images/), any `%` characters present in Custom IDs must be encoded to `%25` in the image delivery URLs.

Make a `POST` request using the example below as reference. You can use custom ID paths when you upload via a URL or with a direct file upload.

```bash
curl --request POST https://api.cloudflare.com/client/v4/accounts/{account_id}/images/v1 \
--header "Authorization: Bearer <API_TOKEN>" \
--form 'url=https://<REMOTE_PATH_TO_IMAGE>' \
--form 'id=<PATH_TO_YOUR_IMAGE>'
```

After successfully uploading the image, you will receive a response similar to the example below.

```json
{
	"result": {
		"id": "<PATH_TO_YOUR_IMAGE>",
		"filename": "<YOUR_IMAGE>",
		"uploaded": "2022-04-20T09:51:09.559Z",
		"requireSignedURLs": false,
		"variants": [
			"https://imagedelivery.net/Vi7wi5KSItxGFsWRG2Us6Q/<PATH_TO_YOUR_IMAGE>/public"
		]
	},
	"result_info": null,
	"success": true,
	"errors": [],
	"messages": []
}
```
