Why Is My Upload Stuck?

Use this page when de-identification or upload starts but does not complete, or processing takes unusually long.

This is the stage where SliceVault de-identifies the files locally in your browser and then uploads them to the repository.

Most Common Causes

• the internet connection is slow or unstable during upload
• many files must be scanned for burned-in annotations
• the images or videos are large, so local de-identification takes time
• the browser is still processing masks or preparing the files for upload

Important Check

If SliceVault is asking you to review burned-in annotations on large numbers of CT or MRI slices, this is often the real cause of the delay. In most cases, the data has been exported as PNG, JPEG, or screen captures instead of DICOM.

Use Why Is SliceVault Asking Me to Mask Every CT or MRI Slice? if that matches what you see.

What to Do

1. Keep the SliceVault page open until processing finishes.
2. If OCR, masking, or rendering is still running, wait for that step to complete.
3. If the batch is very large, try again with a smaller batch.
4. If the upload itself is slow, try a faster or more stable internet connection.
5. If local processing remains very slow, try a more powerful computer.
