Enable flexible variants

Flexible variants allow you to create variants with dynamic resizing which can provide more options than regular variants allow. This option is not enabled by default.

1. In the Cloudflare dashboard, go to the Hosted Images page.

   Go to Hosted images ↗

2. Select the Delivery tab.

3. Enable Flexible variants.

Make a PATCH request to the Update a variant endpoint.

curl --request PATCH https://api.cloudflare.com/client/v4/accounts/{account_id}/images/v1/config \
--header "Authorization: Bearer <API_TOKEN>" \
--header "Content-Type: application/json" \
--data '{"flexible_variants": true}'

After activation, you can use optimization parameters on any Cloudflare image. For example,

https://imagedelivery.net/{account_hash}/{image_id}/w=400,sharpen=3
