Image size increases if the uploaded image is compressed image

[ASAMNYA]

I have noticed when a compressed image is uploaded and if the image quality save is set to 100 then uploaded image size increases significantly.

• If the compressed size is 100 KB and uploaded to server using intervention package with save method and option of '100' image quality then the uploaded image's size increased significantly 700-800KB.

$thumbnailImage->save($originalPath . $uploadFileName, 100);

Original Compressed Image Size 100 KB

After uploading to server via Intervention Package 704 KB

Environment

• PHP Version: 7.4
• OS: Windows 10
• Intervention Image Version: 2.7

The previous compression and optimization is discarded during the decoding and encoding process. This is normal behavior.

The deciding factor is the quality parameter, which in your example is 100, resulting in a very large file size. You can reduce the file size by lowering the value of the parameter. The additional compression optimization must then be done again.
