![]() As already mentioned, 72 and 96 DPI is used for Web pages. ![]() When performing a DPI change, it is important to remember some standard permissions. But when printing, you can output it without changing the DPI. For example, if you have a digital photo taken with a sufficiently powerful camera (5 megapixels or more), and you want to publish it on your blog, you should greatly reduce either the DPI or the size of the photo. In fact, such DPI conversion is the most frequent. It is quite easy to change DPI images if you go to a lower DPI value (for example, when you convert an image from 300 DPI to an image with 72 DPI). You can print the same image with different DPI, and use them in different cases. Next, the DPI you choose is highly dependent on how you intend to use the image. There are printers and plotters with a resolution of 2400 DPI or more. The DPI for the image to be printed is largely dependent on the printer (or plotter) on which it is printed. Good results for printing yields 300 DPI, but it is better to apply 600 DPI. When printing images, different resolutions are used. This is a little better, but still does not go in comparison with the resolution used to print images. This is very small, but for Web pages this is acceptable, since, although the images are far from perfect, they are small in size, and are loaded more quickly. For example, for images on the Internet, 72 DPI is usually used. There are many cases where high image quality is not necessary. This is due to the fact that the resolution of the image is higher, and therefore the image has more details. In general, the higher the DPI of an image, the higher its quality. Abbreviation DPI stands for "dots per inch", and is related to the quality of your photo. When you begin to digitally process your photos, one of the first terms you'll come across is DPI. If you set it to 72DPI, the image size in centimeters will not change, but the size will change in pixels (it will be 288 * 432 pixels). For example, you had an image of 300DPI and 4*6 inches (1200*1800 pixels). This compression can affect quality, but this loss of quality isn’t noticeable to most users.DPI converter has the option to "resample the image", when this option is set, your image will change in size according to the DPI specified in it. JPG is a ‘lossy’ format, meaning that it is compressed to save storage space and make it easier to share. JPEG stands for Joint Photographic Experts Group, which is the name of the committee that standardised the format. However, you can usually adjust settings to save into other formats if needed. Many cameras, smartphones, and basic photo or drawing programs will automatically save into JPG format. JPGs are 2D pixel-based ‘raster’ images, which makes them better for photographs or scans, rather than digital illustrations which are often better as ‘vector’ images. JPG is a universal format which can be opened by almost all image-viewing or -editing programs, by web browsers, and by certain other apps, and they’re supported by most devices. JPG, or JPEG, is one of the most widely used digital image formats. You would typically create a PDF if you wanted to ensure document fidelity, to make it more secure, or to create a copy for storage. Creating a PDF can involve compressing a file, making it take up less storage space. They can be viewed on almost all devices. PDF files aren’t typically created from scratch, but are usually converted, saved or ‘printed’ from other documents or images before sharing, publishing online or storing. It is maintained by the International Organisation for Standardization (ISO). The PDF format is now a standard open format that isn’t just available under Adobe Acrobat. The format has evolved to allow for editing and interactive elements like electronic signatures or buttons. It was developed by Adobe so people could share documents regardless of which device, operating system, or software they were using, while preserving the content and formatting. PDF stands for ‘Portable Document Format’ file.
