Overview

The Resize an Image operation in the "images" resource of this custom n8n node allows users to resize an image file to specified width and height dimensions. This is useful for automating image processing tasks such as preparing images for web uploads, generating thumbnails, or standardizing image sizes for further processing.

Practical examples:

• Automatically resizing user-uploaded profile pictures to a standard size.
• Generating smaller preview images from large originals for faster website loading.
• Batch-processing product images for e-commerce platforms.

Properties

Output

• Binary Data:
  The output contains the resized image as binary data. The binary property name is set by the "Binary Property" input. The output item will have:
  • The original JSON data preserved.
  • A new or updated binary property containing the resized image file, with appropriate filename and MIME type.

Example output structure:

{
  "json": { /* original item data */ },
  "binary": {
    "data": {
      "data": "<Buffer ...>",
      "fileName": "resized-image.jpg",
      "mimeType": "image/jpeg"
    }
  },
  "pairedItem": { "item": 0 }
}

(The actual property name may differ if you set a different value for "Binary Property".)

Dependencies

• External Service: Requires access to the 1001fx API.
• API Key: You must configure the 1001fxApi credentials in n8n.
• Environment: No additional environment variables are required beyond n8n's credential setup.

Troubleshooting

• Common Issues:

  • Invalid Image File: If the input file is not a valid image, the API may return an error.
  • Dimension Limits: If "Width" or "Height" are outside the allowed range (1–10,000), the operation will fail.
  • Missing Binary Data: If the "Image file" property does not point to a valid binary property, the node will throw an error.

• Error Messages:

  • "error": "Cannot read property 'fileName' of undefined"
    Resolution: Ensure the input item contains a valid binary property with the correct name.
  • "error": "Request failed with status code 401"
    Resolution: Check your 1001fx API credentials in n8n.
  • "error": "Invalid width or height"
    Resolution: Make sure the width and height values are within the allowed range.
