Frequently Asked Questions

It sets the DPI value stored inside an image file. DPI, dots per inch, is the number a printer reads to decide how large each pixel should be on paper. Print shops, publishers and submission forms routinely ask for 300 DPI, and most images coming off a phone or a screenshot tool carry either 72 or nothing at all.

No, and this is the part that confuses people. The pixels are left exactly as they were, so nothing is resampled, lost or invented. What changes is the physical size the file claims when it is printed. A 1200 pixel wide image is 4 inches across at 300 DPI and 16 inches across at 72, and it is the same 1200 pixels in both cases.

300 is the standard answer for anything going to print, and it is what most publishers and print shops specify. 150 is enough for a draft, an internal document or a large poster seen from a distance. 72 is the old screen convention. 600 is for line art, scanned documents and fine detail where edges need to stay crisp.

Because on a monitor it is the same size. Screens render pixels, not inches, so a 1200 pixel image occupies 1200 pixels regardless of the DPI tag. The value only takes effect the moment something is printed or placed into a layout that works in physical units, such as InDesign or Word.

Yes, through the Cloudinary API, which is the sensible route when you are preparing a batch of assets for print. If you need to know what an image is already set to, use Check Image DPI, and for working in physical units see Resize Image in Inches.
