来自托管帐户的PHP的JPEG优化

Question

I am looking for a loss-less JPEG optimization tool that I can include in a PHP-based photo gallery software.

I already checked the following question, but ruled out the tools mentioned there for reasons I'll explain below:

Tools for JPEG optimization?

The command line tools jpegtran and jpegoptim are not available in the average PHP hosting account. The web-based tools (www.smush.it, www.kraken.io) all have a limit of 1 MB for processed images.

The 1 MB limit is a problem, because the gallery software delivers images based on browser-size and I also want to support Full HD and even larger displays. Depending on content, photos prepared for such resolutions can get larger than 1 MB.

Any hints on a solution are appreciated!

Answer 1

There are no solution.

Either use some command-line utility or increase memory limit.

(and, to let you know, it's not target image file size but uploaded image dimensions that puts you into trouble with memory limit.
