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

You cannot upload multiple images to a Webflow Collection using a CSV file alone. Webflow only supports one image per image field in a Collection when importing via CSV.

1. Webflow CSV Import Limitations

• You can only assign one image per image field in your CMS item using the CSV import tool.
• The image must be hosted on a publicly accessible URL.
• There is no native support for uploading or mapping multiple images into a multi-image field via CSV.

2. Workarounds Using Multiple Image Fields

• If you must import multiple images per item, the best option is to:
• Add multiple individual Image fields (e.g., Image 1, Image 2, Image 3).
• In your CSV, create separate columns for each image URL.
• Map each column to each Image field during the import.
• This approach is limited in flexibility and scales poorly.

3. Multi-Image Field Import Not Supported

• Webflow’s Multi-Image field (used for galleries, sliders, etc.) cannot be populated via CSV.
• You must manually upload images into a Multi-Image field for each entry or use the Webflow CMS API.

4. Use Webflow CMS API for Advanced Imports

• For importing multiple images into a Multi-Image field:
• Use the Webflow CMS API or third-party automation tools (e.g., Make, Zapier, or a custom script).
• This allows uploading arrays of images to one CMS item, including Multi-Image fields.

Summary

You can’t upload multiple images into a single Webflow Collection field with a CSV file. To achieve this, either use multiple Image fields in the CMS or adopt the Webflow CMS API for a scalable solution.
