How to compress photos below 200kb? On-line image compression in factories using optical second format supports the function of reducing images in batches. Just enter the size of KB you want to compress, and press one key. For example, you can compress a picture to less than 200KB. You can do this:

Optical second format factory

Jpeg (Joint Photographic Experts Group) is a common image file format, which usually adopts ".jpg" or ". Jpeg "as the file extension. The following is the understanding of JPEG format:

Lossy compression: JPEG is a lossy compression image format, which means that it reduces the file size by deleting some details and information in the image. This is usually achieved by deleting some high-frequency data and color details in the image. Although this can significantly reduce the file size, it will also lead to a slight decline in image quality.

Photo and image storage: JPEG format is very suitable for storing photos and images, especially in digital photography. It can effectively compress large photos, making them easier to store and enjoy, while still maintaining sufficient image quality.

Widely used: JPEG images can be viewed and used on computers, mobile devices, social media, websites and other platforms. This is one of the most common image formats on the Internet.

Adjustable compression quality: JPEG allows users to choose different compression quality levels when saving images. A higher quality level will retain more image details, but the file will be larger, while a lower quality level will reduce the file size, but it may lead to image distortion.

Color depth: JPEG supports different color depths, including gray image, color image and true color image. This means that it is suitable for all kinds of images, from black and white photos to color photos.

Image editing: JPEG images can be edited in various image editing software, enabling users to adjust image properties, such as brightness, contrast and color saturation.

Not suitable for lossless editing: JPEG images may lose more details and image quality after repeated editing because of their lossy characteristics. Therefore, JPEG is not suitable for image editing that needs to maintain the highest quality.

In a word, JPEG is a very common image format, especially suitable for photo storage and online enjoyment, but users should pay attention to the possibility of reducing image quality when editing many times.
