# URL to Attachment

> Download files from URLs and save them as Airtable attachments.

## What this tool does

The URL to Attachment tool reads file URLs from a field and downloads those files into an Airtable attachment field. Use it to populate attachment fields from external URLs: product images from an e-commerce feed, documents from a CDN, or files referenced in a spreadsheet import.

## Preview

The URL to Attachment tool has a preview panel that shows a sample of your URL records and confirms the URLs are accessible before running.

## Handling multiple URLs in one field

If a URL field contains multiple URLs separated by commas or newlines, the tool downloads all of them and saves each as a separate attachment on that record.

## Common questions

<AccordionGroup>
  <Accordion title="What happens if a URL returns a 404 or is unreachable?">
    The record is skipped with an error in the execution log. Other records continue processing based on your error handling setting.
  </Accordion>

  <Accordion title="Are there file size limits?">
    Airtable's own attachment size limits apply. Very large files may fail if they exceed your Airtable plan's attachment storage quota.
  </Accordion>

  <Accordion title="Can I use this to download images from Google Drive or Dropbox?">
    Yes, if the URL is a direct download link (not a sharing page URL). Google Drive and Dropbox sharing links need to be converted to direct download format first.
  </Accordion>

  <Accordion title="Does the tool handle redirects?">
    Yes. The tool follows HTTP redirects (301, 302, etc.) to reach the final file URL.
