Preset for this page: 600 DPI
Need an exact print size?
Resample to the pixel count that size needs at the target DPI. The image is fitted inside the size, keeping its shape. Scaling down is harmless; scaling up adds no detail.
How it works
- 1Choose a JPG or PNG, or drag one onto the box.
- 2See the DPI it carries now and what size that prints at. The target is set to 600 DPI.
- 3Press the button. Only the density tag is rewritten — the pixels are copied byte for byte.
- 4If a print shop wants an exact size, use the resample option to get the pixel count that size needs.

Questions
Does converting to 600 DPI make the image sharper?
No, and no tool can. DPI is a note in the file saying how densely to lay the pixels on paper. Changing it changes the printed size, not the detail: the same 1200×1800-pixel photo is 16.7×25 inches at 72 DPI and 4×6 inches at 300 DPI, with identical pixels. When a form insists on "600 DPI", it is checking this note — and this tool sets it.
What if the form also wants a certain size in pixels or inches?
Then the pixel count matters too, and the resample option handles it: pick the print size, and the image is scaled to the number of pixels that size needs at 600 DPI. Scaling down loses nothing you will see in print; scaling up cannot invent detail, and the result says when it has done so.
Which DPI do I need?
300 for photo prints and most print shops; 200 for several passport, visa and exam portals; 600 for fine-art printing and for scans that must go back on paper at size; 72 or 96 for screens. When a portal names a figure, use exactly that figure.
Why does my image show no DPI at all?
Screenshots, images saved from the web and files from some apps carry no density tag; viewers then assume 72 or 96. Setting it explicitly is exactly what those files need.
Is the quality affected?
No. The pixel data is copied byte for byte and only the tag is rewritten, so the result is the same image with a different note attached. Only the optional resample changes pixels, and it says so.
Is my file uploaded anywhere?
No. The file is rewritten inside your browser. Nothing is sent to a server.
Is this the same as "600 dpi converter"?
Yes. It also gets called "convert image to 600 dpi" and "change dpi to 600". They all describe this one job, and this page does it.
