Before sending your photos with WhatsApp or uploading them to your Facebook or Instagram, it can be very helpful to compress them: by reducing their weight you also reduce data consumption and transfer time. To help you optimize the size of your images without losing too much quality, Google has created Squoosh, its own online image compression service. It's free and available from any browser, so you can use it on Windows, MacOS and Linux as well as on Android or iOS devices.
1) Go to the Squoosh website and click on Select an image.
3) Once you have uploaded the image, you will see the screen divided in two:
* On the left side, you will see the original image (you can see its size in the lower-left corner).
* On the right side, you will see the compressed image (the size after optimization is shown in the lower-right corner).
* The Quality indicator serves to define the general degree of image compression. Slide it to the left to make it lighter or to the right to restore the quality (by default you will find it set at 75).
* Check the Resize box if you also want to resize the photo (reduce the number of pixels across the width and height of the image). Use the predefined ratios that you'll find in the Preset drop-down list and remember to always leave the Maintain aspect ratio option enabled to preserve the proportions of the original image.
* Select Reduce palette and move the Colours indicator to the left to reduce the number of colours in the image. After each of these optimizations, you can compare the before and after by dragging the vertical bar that appears on the image.
When you are finally satisfied with the result, click on the download icon at the bottom right to save your new compressed and modified image.
