What is “DPI Converter”?

What can I do with this service?

You can change DPI of your images in two ways: just change the value in the file or resample the image to DPI you specify.

What image formats can I upload to change the DPI?

Currently, images in JPG, PNG, TIF, BMP and ICO formats are supported.

What should I do if I have a different image format?

We recommend that you use our image converter and specify the required DPI when converting. 

What does it mean to “resample image”

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.
For example, you had an image of 300DPI and 4*6 inches (1200*1800 pixels).
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).

What is DPI

When you begin to digitally process your photos, one of the first terms you’ll come across is DPI. Abbreviation DPI stands for “dots per inch”, and is related to the quality of your photo. In general, the higher the DPI of an image, the higher its quality. This is due to the fact that the resolution of the image is higher, and therefore the image has more details. But for high quality you have to pay.

There are many cases where high image quality is not necessary. For example, for images on the Internet, 72 DPI is usually used. 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 images in Windows, 96 DPI is used. This is a little better, but still does not go in comparison with the resolution used to print images.

When printing images, different resolutions are used. Good results for printing yields 300 DPI, but it is better to apply 600 DPI. The DPI for the image to be printed is largely dependent on the printer (or plotter) on which it is printed. There are printers and plotters with a resolution of 2400 DPI or more. Next, the DPI you choose is highly dependent on how you intend to use the image. You can print the same image with different DPI, and use them in different cases.

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). In fact, such DPI conversion is the most frequent. 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. But when printing, you can output it without changing the DPI.

When performing a DPI change, it is important to remember some standard permissions. As already mentioned, 72 and 96 DPI is used for Web pages. Using 150 DPI gives printed images a good quality, but if you want to get good image quality, you should use 300 DPI (or even 600). Sometimes you need to go to a lower DPI, because all other image parameters (the number of megabytes, and the sizes in height and width) with decreasing DPI also decrease.

You can also reduce DPI without changing the height and width of the image. Saving the height and width of the image is possible only when you lower the DPI. In fact, what you do when you reduce DPI images while retaining its original sizes and proportions is simply removing some pixels from the image. You do not change the image itself, but simply make it less detailed.

The DPI image is modified using the appropriate software. For example, our service in many cases performs all the work for you automatically, so you do not have to worry about technical details.

There are programs that allow you to select from a fixed set of permissions (for example, 72 DPI, 300 DPI, etc.). There are also programs that allow the user to enter the desired DPI value himself. When using this program, remember the recommendations in this article about the standard DPI values. One more thing. Although you can separately change the horizontal and vertical DPI, you should not do this without special need.
