A jpg is one of the most common ways to store digital images; the majority of digital cameras process images directly into jpg files; although top end cameras keep the raw data as well. The image is compressed, although not as an exact image, in order to make it as small as reasonably possible it uses something called Lossy compression. This is an irreversible way of compressing the data regarding a picture by using approximations and discarding some of the data whilst keeping enough to have an accurate representation of the picture.
Thus compression is generally completed without visible loss of image quality, even when it is noticeable you may choose to reduce the file, and its quality, more in order to send it via email to friends and family. This file format is often seen as the industry standard.
Advantages of PDF
You will easily locate a variety of businesses on the internet which offer a jpg to pdf convertor online; this may make you wonder why you would need to convert your image into pdf and whether there will be any further loss of image quality. In fact there are several reasons as to why you may find it either desirable or necessary to convert your jpg:
- Jpg files take up space on your computer, the more you compress them the less space they will occupy. However, the smaller the file becomes the worse the quality gets, to the point that the picture is not recognizable! Of course, the picture may still look fine on your computer screen as the pixel size also plays apart in the printed quality. The pixels shown on your computer may not be the same as those shown when you print it. To ensure your printed picture is the same as the image on the screen you will need to convert your jpg to pdf; then what you see is what you get! Of course, a picture saved as a pdf will occupy less space than the same quality picture saved as a jpg, making the pdf option very attractive to anyone concerned about the available storage space.
- An extension of the principle is when you need to send a picture to someone else which will, ultimately be printed. This is generally in a professional context, such as an advert. The jpg file will not provide a high enough pixel rating to print well and look good in your advertising brochure. However, a high resolution pdf file will!
- Multiple images can be difficult to merge using jpgs as you will have sizing and formatting issues. Every picture should be the same quality and resolution to enable you to maneuver them in a third party application and create a mural of your pictures. This process can be complicated and long winded. However, if you use an online jpg to pdf convertor you can merge several jogs into one and create a high resolution pdf file to be used for what every purpose you like. It is still possible to position the images where you would like them to be before saving the new file.
