    Questions

    Does changing the DPI make my image sharper?

    No. DPI only tells printers and layout programs how large to print the pixels you have. More detail needs more pixels: if a print shop needs 300 DPI at 6 × 4 inches, the image must be at least 1800 × 1200 pixels. The DPI calculator works this out, and the image resizer changes the pixel size.

    Why does a form reject my photo for not being 300 DPI?

    Some upload forms read the stored DPI value rather than the pixel size. Setting it to 300 here fixes that without changing the photo itself. Check that the image also has enough pixels for the size the form asks for.

    Which formats does it work with?

    JPG and PNG. WebP and AVIF have no standard place for a DPI value, so programs ignore it there.

    Will my photo’s location and camera details be kept?

    Yes. Only the resolution is changed; EXIF and other metadata stay as they were. To remove them, use Remove Image Metadata.

    Are my images uploaded anywhere?

    No. Your images are opened and processed on your device, and the results are saved straight back to it. Nothing is uploaded. How to check.

    Is it free? Do I need an account?

    It is free to use and there is nothing to sign up for. There are no watermarks and no daily limits.
