Label Studio has a default limit of 250 MB for individual files.
For on-prem installations, you can change this limit by updating the DATA_UPLOAD_MAX_MEMORY_SIZE environment variables.
While we allow file sizes larger than the default, keep in mind that as the size of your file grows, you will see decreased performance.
For very large images, such as those around 2 GB, labeling can become difficult and users have reported issues with the webserver not being able to load the image.
