## Key takeaways

- Upload your deck as a PDF, up to 50 MB. Other formats, such as PowerPoint or Keynote, need exporting to PDF first.
- You can replace or remove the deck as often as you like until you send your application. After that, send a newer deck as a new version from your workspace.
- The file goes to private storage. Nobody, including the fund, opens it until a virus scan says it's clean.
- After you send, your workspace shows the deck moving through Uploaded, Virus scan, Reading slides and With the team.

Upload your deck on the **Deck** step of the application, as a PDF or a PowerPoint file (.pptx) of up to 50 MB. It goes straight to private storage that only the fund's team can open. Every file is scanned for viruses before anyone opens it. The scan runs when you send your application, and your workspace then shows its progress.

## Upload it

1. On the **Deck** step (**Your pitch deck**), drag your PDF onto **Drop your deck here**, or tap **Choose a file**.
2. A bar shows **Preparing**, then **Uploading** with a percentage, then **Finishing**. Tap **Cancel** to stop.
3. When it's done, you see **Deck uploaded** and a card with the file name and size.

The card's label says **Uploaded. Scanned when you send it**. Tap **Replace** to upload a different file, or **Remove** to take it off. You can do both until you send the application.

## Get the PDF right

- PDF and PowerPoint (.pptx) are accepted. From Keynote, Google Slides or Canva, export as PDF or PowerPoint. PowerPoint files with macros (.pptm) and the old .ppt format aren't accepted.
- Keep it under 50 MB. Exporting with smaller images usually fixes a large file.
- Keep the text as text, not pictures of text, so it can be read reliably.
- Don't add a password. A protected PDF can't be read.

## What happens after you send

Your workspace, on the **Application** tab, shows **Your deck** with four steps:

| Step | What it means |
|---|---|
| **Uploaded** | "Uploaded. The virus scan starts in a moment." |
| **Virus scan** | "Checking the file for viruses." |
| **Reading slides** | "Reading your slides." |
| **With the team** | "Your deck is with the team." |

The page updates on its own while this runs. Once your slides are read, the company facts found in them appear under **Check what we read from your deck**, where you can correct them. See [Correct what was read from your deck](/help/applying/correcting-your-details).

If the scan flags the file, the step shows **Not accepted** and "This file couldn't be accepted. Upload a new version of your deck, or contact the fund." Use **Upload a new deck version** to send a clean copy.

If the slides couldn't be read automatically, you see "We couldn't read this file automatically. The fund can see that it arrived and may ask you for another copy."

## Send a new version after you apply

Updated your deck since you applied? Send it from your workspace:

1. On the **Application** tab, under **Your deck**, tap **Upload a new deck version**.
2. In **Upload deck v2** (or the next number), drop the file or tap **Choose the deck file**. PDF or PowerPoint (.pptx), up to 50 MB.
3. A bar shows the upload. Tap **Cancel upload** to stop.

You see **Deck v2 uploaded**. The new version goes through the same steps as your first deck, **Uploaded**, **Virus scan**, **Reading slides**, **With the team**, and the card shows **Version 2**. Your earlier version stays with the team, with everything they noted on it. Once it's read, the facts from the new deck show under **Check what we read from your deck**.

You can send a new version until the fund sends its decision, or until you withdraw your application. After that, the button goes away.

## Frequently asked questions

### Can I change my deck after I send the application?
Yes. Tap **Upload a new deck version** on the **Application** tab. The team gets it as the newest version and keeps the earlier one.

### Who can open my deck?
Only the fund's team, and only after the virus scan says it's clean. Other funds never see it.

### Can I upload a PowerPoint or Keynote file?
PowerPoint, yes: a .pptx file. Keynote: export it as a PDF or as PowerPoint first. The fund sees your slides as pictures with their text, exactly as they look in the file.
