Title: CW Image Optimizer Author: Jacob Allred Published: 27 de julio de 2011 Last modified: 18 de diciembre de 2014 --- Buscar plugins Este plugin **no se ha probado con las últimas 3 versiones mayores de WordPress**. Puede que ya no tenga soporte ni lo mantenga nadie, o puede que tenga problemas de compatibilidad cuando se usa con las versiones más recientes de WordPress. ![](https://s.w.org/plugins/geopattern-icon/cw-image-optimizer.svg) # CW Image Optimizer Por [Jacob Allred](https://profiles.wordpress.org/zulugrid/) [Descargar](https://downloads.wordpress.org/plugin/cw-image-optimizer.1.1.10.zip) * [Detalles](https://es.wordpress.org/plugins/cw-image-optimizer/#description) * [Valoraciones](https://es.wordpress.org/plugins/cw-image-optimizer/#reviews) * [Instalación](https://es.wordpress.org/plugins/cw-image-optimizer/#installation) * [Desarrollo](https://es.wordpress.org/plugins/cw-image-optimizer/#developers) [Soporte](https://wordpress.org/support/plugin/cw-image-optimizer/) ## Descripción The CW Image Optimizer is a WordPress plugin that will automatically and losslessly optimize your images as you upload them to your blog. It can also optimize the images that you have already uploaded in the past. Because CW Image Optimizer uses lossless optimization techniques, your image quality will be exactly the same before and after the optimization. The only thing that will change is your file size. The CW Image Optimizer plugin is based on the WP Smush.it plugin. Unlike the WP Smush.it plugin, your files won’t be uploaded to a third party when using CW Image Optimizer. Your files are optimized using the Linux [littleutils](http://sourceforge.net/projects/littleutils/) image optimization tools (available for free). You don’t need to worry about the Smush.it privacy policy or terms of service because your images never leave your server. **Why use CW Image Optimizer?** 1. **Your pages will load faster.** Smaller image sizes means faster page loads. This will make your visitors happy, and can increase ad revenue. 2. **Faster backups.** Smaller image sizes also means faster backups. 3. **Less bandwidth usage.** Optimizing your images can save you hundreds of KB per image, which means significantly less bandwidth usage. 4. **Super fast.** Because it runs on your own server, you don’t have to wait for a third party service to receive, process, and return your images. You can optimize hundreds of images in just a few minutes. ### Contact and Credits Written by [Jacob Allred](http://www.jacoballred.com/) at [Corban Works, LLC](http://www.corbanworks.com/). Based on WP Smush.it. ## Capturas * [[ * Additional optimize column added to media listing. You can see your savings, or manually optimize individual images. * [[ * Bulk optimization page.

It is also possible that your binaries aren’t accessible to your web server user. You can link these binaries using the following commands: ln -s /usr/local/bin/ opt-jpg /usr/bin/opt-jpg ln -s /usr/local/bin/opt-png /usr/bin/opt-png ln -s /usr/ local/bin/opt-gif /usr/bin/opt-gif ln -s /usr/local/bin/tempname /usr/bin/tempname ln -s /usr/local/bin/imagsize /usr/bin/imagsize ln -s /usr/local/bin/gifsicle /usr/ bin/gifsicle ln -s /usr/local/bin/pngcrush /usr/bin/pngcrush ln -s /usr/local/bin/ pngrecolor /usr/bin/pngrecolor ln -s /usr/local/bin/pngstrip /usr/bin/pngstrip ## FAQ Can I use CW Image Optimizer with a Windows server? No, CW Image Optimizer only supports Linux. Do I have to have littleutils? Yes, CW Image Optimizer will not work if littleutils isn’t installed. This plugin expects _opt-jpg_, _opt-png_, and _opt-gif_ to be in the PATH. ## Reseñas ![](https://secure.gravatar.com/avatar/94839013e8ab66310319b92c091d06bff76e31d35dd61043192e88d956a128ca? s=60&d=retro&r=g) ### 󠀁[Well done!](https://wordpress.org/support/topic/well-done-257/)󠁿 [ksere](https://profiles.wordpress.org/ksere/) 3 de septiembre de 2016 If you have console access to your server and you are able to install the prerequisites it works like a charm!

This plugin is very tiny and does the same job. ![](https://secure.gravatar.com/avatar/79f99591a1d2f777aa515cb51f8bceac2ecc4b3ea851ab4bf8549cc328f87c60? s=60&d=retro&r=g) ### 󠀁[Works well](https://wordpress.org/support/topic/works-well-671/)󠁿 [Robbie_berns](https://profiles.wordpress.org/robbernsteinzgmailcom/) 3 de septiembre de 2016 Installed easily, great compression ![](https://secure.gravatar.com/avatar/ee17d9ff3d72fbbf0ce2e5ef3ce8c2b16be7e3fef9e090daff54a49aac22e12a? s=60&d=retro&r=g) ### 󠀁[Works great](https://wordpress.org/support/topic/works-great-2414/)󠁿 [fmlcorporation](https://profiles.wordpress.org/fmlcorporation/) 3 de septiembre de 2016 Great if you concerned about your privacy. The compression is done in you server with open source tools. The only issue that I had is that I had to disable the installation check. But the instructions in the README file were clear and the it worked great on my images. Not recommended for people who don’t know how to use Linux. ![](https://secure.gravatar.com/avatar/e395b5f0f60d90bc2527af4a351c187352baad4ed1ce341a5729a87e271024a9? s=60&d=retro&r=g) ### 󠀁[ok](https://wordpress.org/support/topic/ok-265/)󠁿 [DominicLindner](https://profiles.wordpress.org/dominiclindner/) 8 de febrero de 2017 ![](https://secure.gravatar.com/avatar/9c1d3a0a896c7ebf2a5cc0c250737de06bfc91ea9c4a680990a57cf71825d3c6? s=60&d=retro&r=g) ### 󠀁[super](https://wordpress.org/support/topic/super-678/)󠁿 [Den999](https://profiles.wordpress.org/den999/) 7 de febrero de 2017 Good.
