## Updating Documents

Upload a new file to an existing document to update it. Existing share links remain unchanged.

<Steps>
  <Step title="Go to Document Details">
    Click the document you want to update to open its detail screen.
  </Step>

  <Step title="Click Update">
    Click the **Update Document** button.
  </Step>

  <Step title="Upload a New File">
    Select and upload a new file (PDF, PPT, or PPTX).
  </Step>

  <Step title="Update Complete">
    After conversion processing, the new version is applied. Viewers accessing the existing share link will see the latest version.
  </Step>
</Steps>

<Tip>
  Updating a document does not change existing share links, so you don't need to send a new link to your viewers.
