Encoding Images

Encoding JPEG Format

public Image::toJpeg(int $quality = 75): EncodedImage

Encode the current image instance in JPEG format in the given quality ranging between 0 for low quality to 100 for best quality.

Parameters

Example

use Intervention\Image\ImageManager;

// create new manager instance with desired driver
$manager = new ImageManager('gd');

// reading gif image
$image = $manager->make('images/example.gif');

// encoding jpeg data
$encoded = $image->toJpeg(90); // Intervention\Image\EncodedImage

Encoding WebP Format

public Image::toWebp(int $quality = 75): EncodedImage

Encode the current image instance in the WebP graphic format in the given quality ranging between 0 for low quality to 100 for best quality.

Parameters

Example

use Intervention\Image\ImageManager;

// create new manager instance with desired driver
$manager = new ImageManager('gd');

// reading gif image
$image = $manager->make('images/example.gif');

// encoding jpeg data
$encoded = $image->toWebp(60); // Intervention\Image\EncodedImage

Encoding PNG Format

public Image::toPng(): EncodedImage

Encode the current image instance in PNG format in the given quality ranging between 0 for low quality to 100 for best quality.

Encoding GIF Format

public Image::toGif(): EncodedImage

Encode the current image instance in GIF format in the given quality ranging between 0 for low quality to 100 for best quality.

Parameters

Handling of Encoded Image Data

All mentioned methods return an Intervention\Image\EncodedImage object. With this instance you can decide how to proceed with the encoded data.

Saving encoded image data in filesystem

public EncodedImage::save(string $filepath): void

Parameters

Example

use Intervention\Image\ImageManager;

// create new manager instance with desired driver
$manager = new ImageManager('gd');

// reading gif image
$image = $manager->make('images/example.gif');

// saving jpeg file
$encoded = $image->toJpeg()->save('images/test.jpg');

Creating Data URI scheme

public EncodedImage::toDataUri(): string

This method takes the already encoded image data and wraps it in an base64 encoded data uri scheme.

Example

use Intervention\Image\ImageManager;

// create new manager instance with desired driver
$manager = new ImageManager('imagick');

// reading gif image
$image = $manager->make('images/example.gif');

// encoding to gif data uri
$data_uri = $image->toGif()->toDataUri();
