Zafar Iqbal

This class can be used to optimize images to fit within a given file size limit.

It takes a picture in any format supported by the GD library and generates a JPEG picture with the maximum quality factor that makes the picture file size not exceed a given limit.

This class is similar to the JPEG Reducer class. It uses the binary search algorithm to reach the ideal quality factor in the smallest number of iterations.

The class stops searching when a given number of limit iterations is reached or when the quality factor difference between the ideal and the found values is less than the configured precision value.

JpegFit

A PHP class that tries to encode an input image to the jpeg file format with a given file size.

It is similar to the JPEG Reducer Class (http://www.phpclasses.org/jpegreducer) but more advanced.

This class uses a binary search algorithm to rapidly locate the jpeg quality setting which is close to the target file size.

Also, the input image can be of JPEG, PNG, GIF, WBMP, and GD2 formats.

If target file size is lower than the minimum possible then lowest quality is used.

If target file size is greater than the maximum possible then the highest quality is used.

If target file size is inbetween then the closest file size will be found, making sure it does not exceed target file size.
