Difference between pdf and jpg

JPEG, on the other hand, is a method that is very commonly used and it actually compresses digital images in what is known as lossy compression. The extension of JPEG files is.

It is especially used for compressing images that are produced by digital photography. The compression can be to varying extents. The two main options that need to be addressed for compression are the size of the file and image quality which are directly proportional.

What is good about JPEG compression is that it achieves a 10 is to 1 ratio of compression and there is hardly any loss of quality in the compression. This is the main difference between the two formats.

Both of these can be converted into the other but generally they are used for different purposes. Note that for the same file that is made available in the two formats, a JPEG image of a certain document will be of a smaller size than the same document as a PDF file.

This is simply because JPEG is a compression method. Moving on, a PDF file preserves the original layout of any document but also leaves the different parts of the document open to editing. Because of their small size, JPGs are ideal for being used for photos on websites. However, they are not good for presenting logos , graphics or line drawings because during the compression process the image loses some of its detail.

This makes images look like bitmaps with lines looking jagged. The PNG format is an open format that was created as an alternative to the GIF format, which required a licensing fee through the company that held a patent for the format. The PNG format offers a better quality graphic than a GIF with better compression and a wider range of color without loss of detail.

Most newer browsers can view PNG formats without any problems. PNG is used almost exclusively for images used on websites. Because of the size of a PNG file, this format is not recommended for photos as JPG is unless file size is not an issue.

If you have a mixture of images that have line art and text, the PNG format will make the image look sharper instead of appearing bitmapped. This makes the PNG format suitable for web images like logos that you want to include transparency and fading effects too. It is not unusual to have a mixture of formats of graphics for your various graphic elements because each format has its advantages and disadvantages of when it should be used dependent on your goals for your website.

This means they will look blocky if you scale them larger than their actual size. For this reason, PDFs are the best choice for saving documents that include text or vector images paths. Bitmap images, such as those taken with a digital camera, are typically saved in the JPEG format. Consequently, if an image of JPEG format is enlarged, it appears blocky and that makes it extremely unsuitable for printing. It is a format of the file that is used for sharing documents containing worded materials, images, bit maps and fonts among different types of computing devices.

It was produced in the early s by a Research and Development team of Adobe Systems. It was launched in as an open standard. Before that it was available as a proprietary format. Apart from graphics and texts, PDF can be also used to send annotations, videos, 3D objects and whatnot. It can contain several pages and file attachments and offers facilities for digital signatures and encryption to carry out important projects, assignments and other important workflows smoothly without any tension about the appropriate hardware, software or operating system to be used for such data transfer.

One can enlarge a PDF file without getting worried about losing the quality of the images and texts contained in it.
