# Uploading invoices

> Drag and drop invoices into Glimps, one or many at a time.

The fastest route for an invoice you already have on your screen.

## Drag and drop

Open the invoice list and drop the files on it. You can also use the upload button and pick files from your computer.

Glimps starts reading straight away. The card in the list shows the progress, and the list updates by itself.

<Check>
  You can keep working while invoices process. Nothing is lost if you close the tab.
</Check>

## Several files at once

Select or drop many files at once. Glimps queues them and works through them in order. Large batches take a few minutes.

<Note>
  Each administration has its own processing queue. If a batch is still running, a new invoice waits its turn rather than slowing everything down.
</Note>

## What you can upload

* PDF, born digital or scanned.
* Images as JPG or PNG, such as a photo of a receipt.
* A UBL XML file, but only together with the PDF of the same invoice under the same file name, such as `invoice-123.pdf` and `invoice-123.xml`.
* One PDF holding several invoices. Glimps notices and asks before splitting.

Each file can be at most 10 MB.

## Attaching an invoice in a chat

You can also drop a PDF into a chat with Luca and ask about it. See [Luca](/ai/luca).

## Deleting an upload

Open the invoice and choose **Delete**. This cannot be undone. An invoice that is on its way to Exact Online, or already booked there, cannot be deleted.
