# Upload an Image

You can upload images to Roboflow projects using the web interface, Python SDK, REST API, and CLI.

{% hint style="info" %}
**Server-side dedup (1.3.6+):** As of `roboflow` 1.3.6, the SDK uploads original image bytes rather than re-encoding via Pillow. The Roboflow server deduplicates uploads by SHA-256 - re-uploading the same file (e.g. into a different batch) succeeds without consuming additional storage credits.
{% endhint %}

{% tab title="Python SDK" %}
**Upload to an Existing Project**

```python
from roboflow import Roboflow

# Initialize the Roboflow object with your API key
rf = Roboflow(api_key="YOUR_PRIVATE_API_KEY")

# Retrieve your current workspace and project name
print(rf.workspace())

# Specify the project for upload
# let's you have a project at https://app.roboflow.com/my-workspace/my-project
workspaceId = 'my-workspace'
projectId = 'my-project'
project = rf.workspace(workspaceId).project(projectId)

# Upload the image to your project
project.upload("UPLOAD_IMAGE.jpg")

"""
Optional Parameters:
- num_retry_uploads: Number of retries for uploading the image in case of failure.
- batch_name: Upload the image to a specific batch.
- split: Upload the image to a specific split.
- tag: Store metadata as a tag on the image.
- sequence_number: [Optional] If you want to keep the order of your images in the dataset, pass sequence_number and sequence_size..
- sequence_size: [Optional] The total number of images in the sequence. Defaults to 100,000 if not set.
"""

project.upload(
    image_path="UPLOAD_IMAGE.jpg",
    batch_name="YOUR_BATCH_NAME",
    split="train",
    num_retry_uploads=3,
    tag_names=["YOUR_TAG_NAME"],
    sequence_number=99,
    sequence_size=100
)
```

**Upload to a New Project**

To upload a new project, add the following code before your model upload:

```python
from roboflow import Roboflow
rf = Roboflow(api_key="YOUR_PRIVATE_API_KEY")

new_project = rf.workspace().create_project(
    project_name="PROJECT_NAME",
    project_license="MIT",
    project_type="PROJECT_TYPE", 
    annotation="PROJECT_DESCRIPTION"
)

"""
Parameters:
- project_name: Preferred project name.
- project_type: Must be one of object-detection, single-label-classification, multi-label-classification, instance-segmentation, or semantic-segmentation.
- project_description: Preferred project description.
"""

```

{% endtab %}

{% tab title="CLI" %}
CLI upload is especially useful if you have a large number of images (i.e. 1,000+) that you want to upload to Roboflow.

**Upload a Single Image**

To upload a single file, use the following command:

```
roboflow upload image.jpg
```

This will ask you which of your projects to upload into, but you can also skip that by specifying it explicitly using the `-p` option to the command.

**Upload an Image and Annotation**

If you have annotations for your image such as a file called `image.xml`:

```
roboflow upload image1.jpg -a image.xml
```

**Upload all Images**

To upload all images in a folder, use the following command:

```
roboflow upload *.jpg
```

**Upload all Images and Annotations**

If you have many images with annotations, you can pass a special “\[filename]” value to the `-a` option that will match the annotation file name based on the name of the image. This would upload image1.jpg with annotations from `image1.xml`, and `image2.jpg` with annotations from `image2.xml`, etc

```
roboflow upload *.jpg -a “[filename].xml”
```

This only works if you have one annotation file for each image. If you have an entire dataset in a common format, like one downloaded from Roboflow Universe, you can also use the `import` command.

**Upload a Dataset**

To upload a full dataset, refer to the Upload Dataset documentation.
{% endtab %}

{% tab title="cURL" %}
**Parameters**

Querystring parameters accepted by the API:

**api\_key**: Obtain from <https://app.roboflow.com/account/api\\>
**image**: \[Optional] URL of the image to add. Use if your image is hosted elsewhere (Required when you don't POST a base64 encoded image in the request body).\
**name**: \[Optional] The filename of the image (if not set, we will try to infer it).\
**batch**: \[Optional] Group images under a batch with this name\
**tag**: \[Optional] Can be specified multiple times. Add tags to uploaded image.\
**split**: \[Optional] One of: train, valid, or test (defaults to train).\
**sequence\_number**: \[Optional] If you want to keep the order of your images in the dataset, you can uploaded images increasing sequence numbers.\
**sequence\_size**: \[Optional] The total number of images in the sequence. Defaults to 100,000 if not set.\
**inference\_id**: \[Optional] The inference ID passed returned from a roboflow inference detection. This inference\_id allows the image to be correlated with a roboflow detection in Model Monitoring (enterprise feature).

**Linux or macOS**

Uploading a local file called `YOUR_IMAGE.jpg` using multipart/form-data (recommended):

```
curl -F name=YOUR_IMAGE.jpg -F split=train \
-F file=@YOUR_IMAGE.jpg \
"https://api.roboflow.com/dataset/YOUR_DATASET_NAME/upload?\
api_key=YOUR_API_KEY"
```

Alternatively, uploading a base64 encoded image:

```bash
base64 -i YOUR_IMAGE.jpg | curl -d @- \
"https://api.roboflow.com/dataset/your-dataset/upload?\
api_key=YOUR_API_KEY&\
name=YOUR_IMAGE.jpg&\
split=train&\
batch=BATCH_NAME_FOR_UPLOAD"
```

Uploading an image hosted on the web via its URL (don't forget to [URL encode it](https://www.urlencoder.org/)):

```bash
curl -X POST "https://api.roboflow.com/dataset/your-dataset/upload?\
api_key=YOUR_API_KEY&\
image=https%3A%2F%2Fi.imgur.com%2FPEEvqPN.png&\
name=201-956-1246.png&\
split=train"
```

**Windows**

You will need to install [curl for Windows](https://curl.se/windows/) and [GNU's base64 tool for Windows](http://gnuwin32.sourceforge.net/packages/coreutils.htm). The easiest way to do this is to use the [git for Windows installer](https://git-scm.com/downloads) which also includes the `curl` and `base64` command line tools when you select "Use Git and optional Unix tools from the Command Prompt" during installation.

Then you can use the same commands as above.

{% tab title="JavaScript" %}
**Node.js**

We're using [axios](https://github.com/axios/axios) and [form-data](https://github.com/form-data/form-data) to perform the POST request in this example so first run `npm install axios form-data` to install the dependency.

**Uploading with multipart/form-data (recommended):**

```javascript
const axios = require("axios");
const fs = require("fs");
const FormData = require('form-data');

const formData = new FormData();
formData.append("name", "YOUR_IMAGE.jpg");
formData.append("file", fs.createReadStream("YOUR_IMAGE.jpg"));
formData.append("split", "train");

axios({
    method: "POST",
    url: "https://api.roboflow.com/dataset/YOUR_DATASET_NAME/upload",
    params: {
        api_key: "YOUR_API_KEY"
    },
    data: formData,
    headers: formData.getHeaders()
})
.then(function(response) {
    console.log(response.data);
})
.catch(function(error) {
    console.log(error.message);
});
```

**Uploading with base64 encoded image (not recommended):**

```javascript
const axios = require("axios");
const fs = require("fs");

const image = fs.readFileSync("YOUR_IMAGE.jpg", {
    encoding: "base64"
});

axios({
    method: "POST",
    url: "https://api.roboflow.com/dataset/YOUR_DATASET_NAME/upload",
    params: {
        api_key: "YOUR_API_KEY",
        name: "YOUR_IMAGE.jpg",
        split: "train",
        batch: "YOUR_BATCH_NAME"
    },
    data: image,
    headers: {
        "Content-Type": "application/x-www-form-urlencoded"
    }
})
.then(function(response) {
    console.log(response.data);
})
.catch(function(error) {
    console.log(error.message);
});
```

**Adding an Image Hosted Elsewhere via URL**

```javascript
const axios = require("axios");

    method: "POST",
    url: "https://api.roboflow.com/dataset/YOUR_DATASET_NAME/upload",
    params: {
        api_key: "YOUR_API_KEY",
        image: "https://i.imgur.com/PEEvqPN.png",
        name: "201-956-1246.png",
        split: "train"
    }
})
.then(function(response) {
    console.log(response.data);
})
.catch(function(error) {
    console.log(error.message);
});
```

**Web**

We are currently beta testing `roboflow.js`, a browser-based JavaScript library which, among other things, includes safe client-side uploads without exposing your secret API Key to the web. If you'd like early access, please [contact us](https://roboflow.com/contact).

## View Uploaded Images in Roboflow

Images uploaded via the API can be found in the `Annotate` tab, under the `unassigned` column and marked as `uploaded via API`.

If you specify a `batch` upload parameter, your image will still be found in the `Annotate` tab but instead of going to the `uploaded via API` batch it will be found in the batch you specified.
