How to compress multiple images in batches without losing quality online for free?

Nowadays it is common to have a large number of images and photos both on the mobile phone and on the computer. These can take up a generous amount of memory. Therefore, one of the ways to free up space on the hard disk of Windows PC is to compress several images in batches without losing quality.

This way consists of the compression of the images to alleviate their weight, by means of an installed program or a web application. In this case, the fastest way is online because it will not be necessary to download any external program.

Although it is also possible to reduce the size and weight of an image , the ideal is to process large quantities in groups to buffer.

Not all the pages that provide this image compression service develop it taking care that its quality is not affected. This can cause inconveniences, because if the original is eliminated and kept compressed, it will not be possible to regain the lost quality.

What is image compression?

This method of reducing the weight of an image consists of changing its resolution or size without affecting the ratio of height and width that it originally presents.

In some cases , the image format is also changed to a lighter one, however, the more compressed the image format is, the longer the device will take to read it, since it has to perform a decompression process.

This is the same for videos. Not all formats are suitable for converting images, as some may affect the quality of the file.
