Change the DPI of images with a few clicks

What is "DPI Converter"?

What can I do with this service?

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

What image formats can I upload to change the DPI?

Images in JPG, PNG, TIF, BMP and ICO formats are currently supported.

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

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

What does "recalculate image" mean?

The DPI converter has the option "Recalculate image". When this option is checked, the image will change according to the DPI specified in it.
For example, you had an image that was 300 DPI and 4 * 6 inches (1200 * 1800 pixels).
If you set it to 72DPI, the image size will not change in centimeters, but the size will change in pixels (it will be 288 * 432 pixels).

What is DPI

When you start digitally processing your photos, one of the first terms you come across is DPI. The abbreviation DPI stands for "dots per inch" and is related to the quality of your photo. In general, the higher an image's DPI, 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 you have to pay for high quality.

There are many cases where high image quality is not required. 72 DPI is typically used for images on the Internet. This is very small, but for websites this is acceptable because, while the images are not perfect, they are small and load faster. 96 DPI is used for images in Windows. This is a little better, but still doesn't compare to the resolution for printing pictures.

Different resolutions are used when printing images. Good results when printing are 300 dpi, but it is better to use 600 dpi. The DPI for the image to be printed depends largely on the printer (or plotter) it is being printed on. There are printers and plotters with a resolution of 2400 dpi or more. Next, the DPI you choose depends a lot on how you plan to use the image. You can print the same image at different DPI and use it in different cases.

It's pretty easyDPI Change images when you go to a lower DPI (for example, when converting a 300 DPI image to a 72 DPI image). In fact, such a DPI conversion is the most common. For example, if you took a digital photo with a powerful camera (5 megapixels or more) and want to post it on your blog, consider reducing either the DPI or the size of the photo heavily. But when printing, you can output it without changing the DPI.

When making a DPI change, there are a few default permissions that you need to remember. As mentioned earlier, 72 and 96 DPI are used for web pages. Using 150 DPI gives good quality printed images, but if you want 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) also decrease as the DPI decreases.

You can also reduce DPI without changing the height and width of the image. Saving the height and width of the image is only possible if you decrease the DPI. What you do when you reduce DPI images while keeping their original sizes and proportions is simply removing a few pixels from the image. You're not changing the picture yourself, just making it less detailed.

The DPI image is changed using the appropriate software. For example, in many cases our service automatically carries out all work for you so that you don't have to worry about technical details.

There are programs that allow you to choose from a fixed set of permissions (e.g. 72 DPI, 300 DPI, etc.). There are also programs that allow the user to enter the desired DPI value himself. When using this program, keep in mind the recommendations in this article about the default DPI values. Just one thing. While you can change the horizontal and vertical DPI separately, you shouldn't do so without special need.
