In this article, you will learn about what JPG and PNG are, why to convert from one to the other, and how to do this safely and efficiently.
What is a JPG?
Definition and History:
JPG is an image format that is quite popular and is based on the Joint Photographic Experts Group, which uses quite a effective compression algorithm.
The JPEG format was developed in 1992 and came to be widely used because of a good compromise between quality and file size. JPG is commonly used in photographs and other images where specifics of file size need to be decreased.
Compression Method:
JPG employs lossy compression, and that is where it rids an image of some of its file size. The level of compression can be controlled; the higher the level of compression applied the poorer the quality of the picture but the smaller the file size.
For example, a high compression setting will make the file very small but the image quality will be poor to the extent that it may show signs of customers such as blurring or pixelation.
What are the Benefits of JPG?
1. Efficient Compression: These files have less size than many other image formats, this makes them very useful when uploading images to web pages, mailing them, or even sharing them on social sites.
2. Broad Compatibility: JPG is popular and on most of the web browsers, image viewers, and the image edited applications means it has diversified compatibility.
3. Good for Photographs: JPG is suitable for photographs and detailed pictures since the type degrades the quality of the image a little but at the same time does not allow for the creation of obscenely large files.
What are the Drawbacks of JPG?
1. Lossy Compression: JPG compression is characterized by loss of data and, therefore, the quality of images decreases; it is even worse if the image is processed several times.
2. No Transparency: JPG does not support transparency and that is why it would not be suitable for images that need to have a transparent background, for instance, logos or icons.
What is a PNG?
Definition and History
Another image file format that is quite popular at present is PNG or Portable Network Graphics which was developed in 1996 as a replacement for GIF. PNG was created in order to include lossless compression and alpha-channel /transparency issues that were missing in the JPG format.
Compression Method
PNG utilizes lossless compression and as such, the compression of data does not entail a loss of data. This means that PNG files are able to maintain the quality of the image even if they are edited and saved countless times. It also controls various color depths with support for grayscale and for full-color images including alpha premultiplication.
What are the Benefits of PNG?
1. Lossless Compression: On the other hand, PNG files compress images without losing the original quality of the image, implying that they should be used for best-quality images.
2. Transparency Support: PNG does support transparency whereby an image could be created with a black background. The blending modes come in very handy especially when designing logos, icons, or any graphic element that has to be placed on top of other backgrounds.
3. High Quality for Graphics:
Keywords PNG is good for images with clear-cut edges illustrations, small texts, detailed graphics objects like screenshots or interface elements, etc.
What are the Drawbacks of PNG?
1. Larger File Sizes: Most of the time, PNG files are larger than JPG files because of their capability to compress without losing quality. This can be a disadvantage, especially on the use of the web since it creates larger file sizes.
2. Not Ideal for Photographs: Indeed, when it comes to graphics and text, the PNG surpasses JPG, but when it comes to compressing photographs, where minor changes of shades are frequently used, the JPG proves to be more effective.
