HEIC Converter API

HEIC Converter transforms Apple HEIC and HEIF images to web-friendly formats. Perfect for processing iPhone photos that need to be converted for websites, apps, or services that don't support HEIC.

This is a Javascript Wrapper for the HEIC Converter API

Installation

Using npm:

npm install @apiverve/heicconverter

Using yarn:

yarn add @apiverve/heicconverter

Configuration

Before using the HEIC Converter API client, you have to setup your account and obtain your API Key. You can get it by signing up at https://apiverve.com

Quick Start

Get started with the Quick Start Guide

The HEIC Converter API documentation is found here: https://docs.apiverve.com/ref/heicconverter. You can find parameters, example responses, and status codes documented here.

Setup

const heicconverterAPI = require('@apiverve/heicconverter');
const api = new heicconverterAPI({
    api_key: '[YOUR_API_KEY]'
});

Usage

File Upload

This API requires a file upload. Use executeWithFile() to upload files:

// Upload a file (path, Buffer, or ReadStream)
api.executeWithFile('/path/to/file.image', options, callback);

Accepted file types: .heic, .heif Maximum file size: 10 MB

Available Parameters

Pass additional parameters via options.fields:

| Parameter | Type | Description | |-----------|------|-------------| | outputFormat | string | Target format (required) | | quality | integer | Output quality (applies to jpg/webp) | | maxWidth | integer | Maximum width in pixels (maintains aspect ratio) | | maxHeight | integer | Maximum height in pixels (maintains aspect ratio) |

api.executeWithFile('/path/to/file', {
    fields: {
        outputFormat: 'png',
        quality: 90,
        maxWidth: 1920,
        maxHeight: 1080
    }
});

Perform Request

Using the API is simple. All you have to do is make a request. The API will return a response with the data you requested.

// This API requires a file upload
// You can pass a file path, Buffer, or ReadStream
var filePath = '/path/to/image.heic';

api.executeWithFile(filePath,
    {
        fields: {
        outputFormat: 'png',
        quality: 90,
        maxWidth: 1920,
        maxHeight: 1080
        }
    }, function (error, data) {
    if (error) {
        return console.error(error);
    } else {
        console.log(data);
    }
});

Using Promises

You can also use promises to make requests. The API returns a promise that you can use to handle the response.

// This API requires a file upload
// You can pass a file path, Buffer, or ReadStream
var filePath = '/path/to/image.heic';

api.executeWithFile(filePath, { fields: { /* parameters */ } })
    .then(data => {
        console.log(data);
    })
    .catch(error => {
        console.error(error);
    });

Using Async/Await

You can also use async/await to make requests. The API returns a promise that you can use to handle the response.

async function makeRequest() {
    // This API requires a file upload
// You can pass a file path, Buffer, or ReadStream
var filePath = '/path/to/image.heic';

    try {
        const data = await api.executeWithFile(filePath, { fields: { /* parameters */ } });
        console.log(data);
    } catch (error) {
        console.error(error);
    }
}
