Compress JPEG & PNG images

Make your webshop faster by compressing your JPEG and PNG images. This plugin automatically optimizes your images by integrating with the popular image compression services TinyJPG and TinyPNG.

How does it work?

When you view a product in your webshop Magento creates different image sizes in its cache folders. This extension will compress these images for you automatically.

In the background your product images are uploaded to the TinyJPG or TinyPNG service and analyzed to apply the best possible compression. Based on the content of the image an optimal strategy is chosen. The result is sent back to your Magento webshop and saved in your cache folder.

On average JPEG images are compressed by 40-60% and PNG images by 50-80% without visible loss in quality. Your webshop will load faster for your visitors, and you’ll save storage space and bandwidth!

Getting started

Obtain your free API key from https://tinypng.com/developers. The first 500 compressions per month are completely free, no strings attached! As each product will be shown in different sizes, roughly 100 products can be uploaded to your Magento webshop and compressed for free. You can also change which of the generated image sizes should be compressed, because each one of them counts as a compression. If you’re a heavy user, you can compress additional images for a small additional fee per image by upgrading your account.

Installation instructions

The extension can be installed on your system as follows:

Use Magento Connect Manager and install the extension
Log off first and then log in to your Magento Admin Panel
Go to System > Configuration
Click on "JPG & PNG compression"
Enter your TinyPNG API key
Select the image types to be compressed
Upload a new image and view it in your catalog

You can clear the existing image cache in case you like to compress all existing product images:

Go to System > Cache Management
Click on "Flush Catalog Images Cache"
Now view your catalog so the image cache is recreated
The product images will be compressed automatically

You can inspect the number of compressions by logging in to your TinyPNG developer subscription from https://tinypng.com/developers. For debugging purposes you can also enable Developer Logging in Magento. When this is enabled and the extension is installed correctly it will save its progress to the file /var/log/image-compression.log.
