Installation

Run command in your project's root directory

composer require maestroerror/php-heic-to-jpg

Usage

Using the class "HeicToJpeg" is extremely simple. You need full location of any HEIC image to pass in "convert" function and call "saveAs" (save as file) or "get" (get file contents) methods.

// 1. save as file
Maestroerror\HeicToJpg::convert("image1.heic")->saveAs("image1.jpg");
// 2. get content (binary) of converted JPG
$jpg = Maestroerror\HeicToJpg::convert("image1.heic")->get();

For MacOS users

It should detect the OS itself, but if you want to specify architecture, it is recommended to use convertOnMac instead. The second argument is architecture of your system, by default set as "amd64", but you can specify "arm64" (AArch64, M1)
Note: As reported by several users, M1 Macbook works on amd64 binary file, so if arm64 doesn't work for you, just try convertOnMac("image1.heic")

// By default
Maestroerror\HeicToJpg::convertOnMac("image1.heic", "arm64")->saveAs("image1.jpg");

Force arm64 for linux

In case of linux, for some reason, if it doesn't detect your architecture correct or just the php-heic-to-jpg-linux-arm64 binary is working for you well, (From v1.0.4) you can force it to use in convert and convertFromUrl by passing true as third argument:

Maestroerror\HeicToJpg::convert("image1.heic", "", true)->saveAs("image.jpg");

isHeic method

Before converting, you can use the isHeic method (contributed by pbs-dg) to check if a file is HEIC format.

$fileIsHeic = HeicToJpg::isHeic("image.heic");
if ($fileIsHeic) {
    // Your code
}

convertFromUrl method

If your image is available publicly, you can easily convert and save it in your file system using convertFromUrl method:

Maestroerror\HeicToJpg::convertFromUrl("https://github.com/MaestroError/php-heic-to-jpg/raw/maestro/tests/Unit/images/image1.heic")->saveAs("image1.jpg");

Handling 'mdat' File Conversion Issues

If you encounter an issue where the module cannot convert certain images produced by Samsung devices (detailed in this issue), resulting in the error error reading "meta" box: got box type "mdat" instead, you can take the following steps:

heif-converter-image is already required by composer in this (php-heic-to-jpg) package. heif-converter-image depends on libheif and provides installation scripts for various platforms refer to it's documentation.

• Ensure you have maestroerror/heif-converter required in composer by running composer require maestroerror/heif-converter.

• Make sure libheif is installed on your system. You can check the libheif for installation instructions or use installation script for your platform provided by heif-converter-image.

The php-heic-to-jpg package automatically detects the presence of the heif-converter-image package and will attempt to use its Command Line Interface (CLI) executable for conversion if default conversion fails.

In case the package cannot find the heif-converter-image CLI, you can specify the path as an argument in the convert and convertOnMac methods like so:

HeicToJpg::convert("image.heic", "path/to/your/bin/heif-converter-{linux/windows/macos}")->saveAs("image.jpg");
HeicToJpg::convertOnMac("image.heic", "arm64", "path/to/your/bin/heif-converter-macos")->saveAs("image.jpg");
HeicToJpg::convertFromUrl("SOME_URL", "path/to/your/bin/heif-converter-{linux/windows/macos}")->saveAs("image.jpg");

With these steps, you should be able to handle the conversion of images that were previously causing issues.

Added pest test and workflows for linux, windows and macos. Run tests locally with ./vendor/bin/pest

To Do

• Find out if it can be used with docker CLI command from PHP, add in docs if yes
• Try to update to Go 1.21 version
• Add github action for generating executables
• Add issue #33 and solution as arm64 example
• Add changes from issue #28 (try/catch)
• Add alternative packages in Docs from this issue comment
