Remove image backgrounds in n8n

Option A: the lassocut node

1. In n8n, open Settings → Community nodes → Install and enter n8n-nodes-lassocut.
2. Add the lassocut node to your workflow (search for remove background) and choose Remove Background.
3. Create the lassocut API credential with a key from your account.
4. Set Input to a binary file from a previous node, or to an image URL.

The node returns the cut-out as a binary file (field data by default, named <name>-removebg.png) with credits_charged, width, height and detected_type in the JSON. Options: size, subject type, format, background colour, crop to subject, crop margin. Errors are readable, and Continue On Fail works per item.

Option B: keep your HTTP Request node

If your workflow calls the API with an HTTP Request node, change the URL and the key. Everything else stays: the image_file or image_url field, the options, and Response Format: File.

- URL: https://api.remove.bg/v1.0/removebg
+ URL: https://api.lassocut.com/v1.0/removebg
- Header X-Api-Key: your remove.bg key
+ Header X-Api-Key: your lassocut key

If you want the image itself, send Accept: image/* or no Accept header at all: with Accept: application/json the API answers JSON with the image in base64, exactly like remove.bg.

Questions

Does it work on n8n Cloud?

The HTTP Request option works everywhere today. The lassocut node installs on self-hosted n8n today; on n8n Cloud it appears once n8n has verified it.

What does it cost?

The same as any API call: 50 free previews per month, then credit packs that never expire. See pricing.

Zapier or Make?

Integrations are on the way. Until then, both can call the API with their HTTP modules using the same two changes.
