Besides resizing, File & Image Uploader Pro allows you to convert and compress your images prior upload. To achieve this, resizeMimeType and/or resizeQuality can be set in the JSON transformation parameters.

• resizeMimeType: Conversion to image/jpeg is supported
• resizeQuality: Compression rate of the image, number between 0 and 1 (1 means no compression)

The following JSON snippet in the transformation parameters attribute will result in PNG images to upload with an 85% compression rate.

When converting to jpeg, extension change might be required. Refer to renaming for more details.
