DPI ("dots per inch") only means something once you decide to print an image — it's the ratio between how many pixels the image has and how large you want it on paper. The same 2000×2000px photo is a tiny 6.7-inch square at 300 DPI (good for print) or a huge 27.8-inch square at 72 DPI (fine for a screen, blurry on paper). On a screen, DPI doesn't change anything: a 1000px-wide image looks the same whether its metadata says 72 or 300.
My image says 72 DPI — is that a low-quality photo?⌄
No. 72 is just a leftover default from old Mac displays that many cameras, screenshot tools, and editors still write into an image's metadata regardless of actual quality. What determines sharpness is the pixel dimensions, not this number — that's why this tool shows both.
What DPI should I use for printing?⌄
300 DPI is the standard for sharp, close-up printing (photos, flyers, business cards). 150 DPI is acceptable for larger prints viewed from a distance, like posters. Use the "Calculate at" field above to see your image's real print size at any DPI before you send it to a printer.
