Convert an image from BMP to ICO

Transloadit's API makes light work of changing the format of images from BMP to ICO. Whether we need to convert directly as your users upload, or processing entire media libraries in the background, you can use 🤖/image/resize and set its format parameter to the appropriate value.

In this case "ico" to convert to Microsoft icon images. Because we chose the ICO format, we will need to reduce the dimensions to officially max 256×256 pixels, but we'll go smaller (32×32) for compatibility reasons. We'll accept any image as input, no need to define that, but in this demo, we'll be uploading Microsoft Windows bitmap image images (BMP).

Transloadit supports over 40,000 image conversion format pairs. Combined with {{ collections.robots.size | minus: 1 }} other Robots, this easily makes us the most versatile conversion API on the planet.

Step 1:

Handle uploads

We can handle uploads of your users directly.Learn more

cat.bmp

Image – 2.5 MB

1152 × 768

":original": {
  "robot": "/upload/handle"
}

/upload/handle

This bot receives uploads that your users throw at you from browser or apps, or that you throw at us programmatically

Step 2:

Convert, resize, or watermark images

We can resize, crop, and (auto-)rotate images, or apply watermarks and other effects, and much more.Learn more

cat.ico

Image – 4.2 KB

32 × 32

"converted": {
  "use": ":original",
  "robot": "/image/resize",
  "result": true,
  "format": "ico",
  "height": 32,
  "resize_strategy": "fillcrop",
  "width": 32
}

/image/resize

This bot resizes, crops, changes colorization, rotation, and applies text and watermarks to images

Step 3:

Export files to Amazon S3

We export to the storage platform of your choice.Learn more
