Uploading to S3 from Laravel Quality Lost

Question

My application uploads images to s3. I use front-end rendering to get the colors of the image, but because uploading to s3 lowers the quality (jpeg'ish), I get more colors then desired.

$s3 = \Storage::disk('s3');
$s3->put('/images/file.jpg', '/images/file.jpg', 'public');

Is there way to prevent this quality loss? I noticed that if I upload the file directly using aws console website, the quality stays the same which is ideal.

Thank you!

Answer 1

In the controller Action

public function uploadFileToS3(Request $request)
{
    $image = $request->file('image');
} 

Next we need to assign a file name to the uploaded file.You could leave this as the original filename, but in most cases you will want to change it to keep things consistent. Let’s change it to a timestamp, and append the file extension to it.

$imageFileName = time() . '.' . $image->getClientOriginalExtension();

Now get the image content as follows

$s3 = \Storage::disk('s3');
$filePath = '/images/file.jpg' . $imageFileName;
$s3->put($filePath, file_get_contents($image), 'public');

Answer 2

I am not familiar with Laravel but i am familiar with AWS S3, and i'm using aws-sdk-php.
As far as i know, neither AWS S3 nor php-sdk don't do something implicitly under the hood. So it must be something going wrong elsewhere in your project.
You can try use plain aws-sdk-php:

$s3 = S3Client::factory([
    'region'      => 'us-west-2',
    'credentials' => $credentials,
    'version'     => 'latest',
]);
$s3->putObject([
    'Bucket'     => 'myBucket',
    'Key'        => 'test/img.jpg',
    'SourceFile' => '/tmp/img.jpg',
]);

It works perfectly.
