Can I upload multiple images to a Webflow Collection using a CSV file?

TL;DR
  • CSV imports in Webflow only support one image per field using Image fields, not Multi-image fields.
  • For multiple images, use separate Image fields, manually upload to Multi-image fields after import, or automate via the Webflow API using hosted image URLs.

You cannot upload multiple images to a single multi-image field in a Webflow CMS Collection using a CSV file directly. Webflow's CSV import tool only supports one image per field using an Image field, not the Multi-image field.

1. Webflow CSV Imports Only Support Image Fields, Not Multi-image Fields

  • When using CSV import, each image must correspond to a unique Image field in the CMS.
  • Multi-image fields are not supported during CSV imports—even if you include URLs separated by commas or semicolons.

2. Workarounds for Importing Multiple Images

To handle multiple images for a CMS item, consider one of the following alternate methods:

  • Create Multiple Image Fields: Add multiple single Image fields (e.g., Image 1, Image 2, Image 3) in the Collection and map each one to its corresponding image URL in the CSV.
  • Use Multi-image Field Manually: After importing basic content via CSV, manually upload images to the Multi-image field for each CMS item.
  • Use Webflow API with third-party tools (e.g., Make/Integromat, Zapier):
  • Upload images and assign them programmatically to Multi-image fields using the API.
  • This requires some technical setup, as Webflow’s API accepts multi-image uploads.

3. Image Hosting Requirements

  • For CSV imports or API uploads, images must be hosted on publicly accessible URLs (e.g., Dropbox direct links, AWS S3, or Imgur).
  • The image field requires the full URL ending with an image extension (e.g., .jpg, .png).

Summary

You cannot upload multiple images into a Multi-image field using a CSV file in Webflow. Only single Image fields are supported in CSV imports. To include multiple images, either add several Image fields in your Collection, upload to Multi-image fields manually post-import, or automate using the Webflow API.
