Compressing and decreasing the photo size certainly lowers the picture quality a chip. But in most cases, you won't notice much divergence. Hither are seven quick and free ways to compress photos on Mac one at a fourth dimension or several in batch/bulk.

Factors on which the image file size depends

The file size of a photograph depends on diverse things like:

• Prototype dimensions: A 1920 10 1080 image will have a bigger file size than a 720 x 480 epitome.
• Image format: For most pictures, JPG/JPEG tends to have a smaller file size than PNG. But if your image is mainly text-based, PNG is amend.
