@image-kit/core v2.0.9

@image-kit/core 🖼️

A lightweight and performant image processing wrapper for the browser. Built using native browser APIs like Canvas, HTMLImageElement, and WebCodecs, this library provides a powerful yet minimal interface to perform real-time image transformations such as resizing, format conversion, quality tuning, and more.

✨ Features

• 🪶 Minimal footprint
• 💨 Fast performance via native browser APIs
• 🧩 Chainable API for better readability
• 🎨 Resize, format, sharpen, compress, and transform with ease
• 🧪 Converts final result to Blob, Base64, or ImageBitmap

📦 Installation

npm install @image-kit/core
# or
yarn add @image-kit/core
# or
pnpm add @image-kit/core

🚀 Usage

import { image, thumbnail } from "@image-kit/core";

const src = "https://example.com/image.jpg";
const height = 200;
const aspectRatio = 16 / 9;

const transformedImage = image(`${src}?${Date.now()}`)
  .format("auto")
  .quality(1)
  .resize(thumbnail().height(height).aspectRatio(aspectRatio))
  .sharpen(1)
  .algorithm("multistep");

const blob = await transformedImage.toBlob();

🔧 API Reference

image(src: string)

Initializes image processing with the provided image source.

.format(format: 'auto' | 'jpeg' | 'webp' | 'png')

Automatically choose optimal format or specify it manually.

.quality(value: number)

Set the image quality (0-1).

.resize(config: ResizeConfig)

Resize the image using configuration (supports width, height, and aspectRatio).

.sharpen(value: number)

Sharpens the image. 1 is typically a safe default.

.algorithm(name: 'default' | 'multistep')

Chooses resizing algorithm.

.toBlob()

Returns a Blob of the transformed image.

.toBase64()

Returns a base64 data URL.

.toImageBitmap()

Returns an ImageBitmap.

🧱 Resize Utilities

thumbnail()

Returns a predefined ResizeConfig that simplifies resizing logic for thumbnails.

Example:

resize(thumbnail().height(300).aspectRatio(16 / 9))

🧪 Browser Support

🧠 Philosophy

Less dependency, more browser power. Use what the platform gives you. This library is for those who want fast, predictable image processing without third-party bloat.
