Where to store files

If your task requires images, audio, or video files, you can upload them:

Photo hosting

Some photo hosting services are free and don't require registration. This way you can quickly and easily upload your files and get links to them. But they have limitations. We recommend that you read the terms of use before using photo hosting services.


The information about the terms is provided here for informational purposes.

The terms may be changed by the service unilaterally. You can view changes on the photo hosting website.

Toloka is not responsible for such changes or for placing them in this section within a certain timeframe.

How to upload an image to photo hosting

For example, imgbb:

  1. Go to the photo hosting website.

  2. Click Start uploading.

  3. Select files from your device. Before uploading, you can change the image size and add a title or description.

  4. Click Upload.

  5. In Embed codes choose HTML full linked.

  6. Copy the link, which is indicated in quotation marks after src= (for example, https://i.ibb.co/HhK1B5J/image.png), and add it to the file with tasks.

Cloud storage

In Object Storage terms, files and folders are objects. All objects are stored in buckets. A bucket is a logical entity that helps organize object storage.

Cloud storage enables users to store large amounts of data. You need to pay to use it. To try out a service, use a free trial.

Creating a file with tasks

To use a file in the task interface, you should have a field of URL type in your project's input data. You'll need the name of this field later when creating a file.

In the file with the tasks, paste the links into the column that matches the input data field to which this data is passed.

For example, if you want to use images in the image field, specify the file links in the INPUT:image column:

Amazon S3
Azure Blob Storage
Google Cloud Storage
Yandex Object Storage
