Compress JPEG Images Online Select up to 20.jpg or.jpeg images from you device. Or drag files to the drop area. Wait for the compression to finish.

However, this also increases the file size, and this can be problematic when creating web-friendly content. Generally, a resolution of about 70 pixels per inch is enough for digital needs.
