Instagram Image Resizer

Resize and optimise images for Instagram post sizes.

This library can take a single image path or a folder containing multiple images and create images ready to be publish as Instagram posts.

Examples

How it works

Resize a single image

To resize a single image src/image.jpg and save new images in the folder output, you can use it from the command line:

# npx instagram-image-resizer (sourceImagePath) (destinationPath)
npx instagram-image-resizer src/image.jpg output

or in your code:

npm install instagram-image-resizer

import resizer from "instagram-image-resizer";

// resizer(sourceImagePath, destinationPath)
const destinationFilesPaths = await resizer("src/image.jpg", "output");

// destinationFilesPaths will be an array containing the new file/files' paths

For example, for the horizontal image src/image.jpg, it will create 3 new images: output/image-1.jpg, output/image-2.jpg, output/image-3.jpg.

Resize a folder containing multiple images

To resize multiple images contained in a folder src, and save new images in the folder output, you can use it from the command line:

# npx instagram-image-resizer (sourceImagesFolderPath) (destinationPath)
npx instagram-image-resizer src output

or in your code:

npm install instagram-image-resizer

import resizer from "instagram-image-resizer";

// resizer(sourceImagePath, destinationPath)
const destinationFilesPaths = await resizer("src", "output");

// destinationFilesPaths will be an array containing the new files' paths

For example, if the source folder src will contain 2 vertical images src/cat.jpg and src/dog.jpg, it will create 2 new images: output/cat-1.jpg, output/dog-1.jpg.
