  1. Nice content Obasi..!
    I use this tool and it’s so amazing but one thing which i want to tell you is that tinypng never converts files above 5 MB. You can also compress pdf files online free using these tools.

  2. Hi Obasi,

    Nearly 4 years since you published this review and most of the tools listed are going strong even today, in 2017!! Great going.

    It would interest you to know that we have recently rolled out a similar online service that we call Slim N Trim. While we continue to improve the service, we hope you and the readers here will find Slim N Trim useful:

  3. Awesome post. My choice is image optimizer.

  4. i think this png/jpg/image compressor is better as it allows 50 files in one chance. plugin is not recommended as it will always keep your server loaded with excess load. i agree that it will automate the process but when you can do samething in 1 second through online without slowing down your website then i think that is the best. if you know any better then kindly share link.
    Get rid of Plugin and make super fast website. It takes 1 second to just browse your all files.(yes all files as you wont need more than 50 files for any article) so just upload and get compressed file instantly and enjoy the fast website.
