DPI and pixel size solve different problems. Changing DPI only rewrites a metadata number; resizing actually changes how many pixels your image contains — which is what determines real print quality and detail. Use this free image resizer when a print shop asks for specific dimensions (for example 1800×1200 px for a 6×4″ print at 300 DPI), when a website enforces a maximum width, or when you need to shrink a huge photo before emailing it.

Type exact width and height in pixels, or scale by percentage — 50 to halve the image, 200 to double it. The aspect-ratio lock keeps your photo from stretching, and you can export to JPG, PNG, or WEBP in the same step. Like every tool here, resizing happens entirely in your browser: no uploads, no queues, no watermarks.

Need both? Resize the pixels here first, then set the DPI metadata with the free DPI converter — that combination is exactly what “print-ready” means.
