Change an image’s DPI (dots per inch) metadata online. DPI tells print software how large to print an image — 300 DPI is the usual target for crisp printing. This sets the DPI tag without resampling, so your pixels are untouched.
What DPI is (and isn’t)
DPI (dots per inch) is a tag that tells print software how large to print an image; 300 DPI is the standard for sharp photo prints. It has no effect on how the image looks on screen and does not change the pixels — it only changes the intended print size. Print shops and submission specs often require a specific DPI, which is exactly what this sets.
Does changing DPI affect quality?
No. This tool writes the new DPI value without resampling, so the pixels are untouched and the file looks identical. A higher DPI does not add detail — for more actual resolution you need more pixels, so resize up or use AI upscale. Your image is uploaded to do the work and deleted automatically an hour later.
How to set DPI on an image
- 1Upload your image.
- 2Enter the DPI you need, such as 300 for print.
- 3The tool writes the new DPI value into the file.
- 4Download the image with its updated DPI.
When to use Change DPI
- Preparing an image for a print shop that requires 300 DPI.
- Meeting a submission spec that states a DPI value.
- Setting print resolution metadata without changing the pixels.
Frequently asked questions
Does changing DPI change image quality?
No. DPI is a print-size tag; this tool changes that number without resampling, so the pixels and on-screen appearance stay exactly the same.
Will a higher DPI make my image sharper?
Not on screen. DPI only affects how big the image prints. For more actual detail you need more pixels — resize up or upscale.
What DPI should I use for printing?
300 DPI is the standard for sharp photo prints. Large banners viewed from a distance can use less.
