Change DPI
DPI only stores how large the image should print. It does not change the pixel size.
See image dimensions, format, DPI and camera metadata
An image file contains more than the picture you see. It may include the pixel dimensions, file type, DPI setting, camera model, capture date and EXIF details such as exposure or orientation. This inspector shows that information in one place and also lets you change the DPI metadata or remove metadata before sharing a file. It is useful when a form asks for a specific DPI, when a photo appears rotated, or when you want to check whether a picture still contains location or device information.
How to inspect an image
- Select an image or drag it into the drop zone.
- Review the file details, dimensions and any camera or EXIF information shown.
- If you need a particular print density, enter a new DPI value or choose a common preset.
- Choose the output format and click Save with new DPI.
- To strip hidden metadata, use Remove metadata & download and keep the cleaned copy.
What the details are useful for
- Print preparation: check whether an image has enough pixels for the requested print size.
- Form requirements: some portals ask for a specific DPI or pixel dimension.
- Privacy checks: see whether a photo contains camera details or GPS information before posting it.
- Troubleshooting: understand why a photo opens sideways or why a website rejects a file.
DPI, pixels and metadata explained
DPI describes how densely an image should be printed; it does not by itself add pixels or improve quality. A 1200 × 1800 pixel image printed at 300 DPI is about 4 × 6 inches. Changing the DPI value changes the intended print size, not the amount of detail in the file. EXIF data can include the camera model, date, orientation and sometimes GPS coordinates. Removing metadata is a sensible step before sharing a personal photo publicly. This tool can clean the file and save a copy, but always keep the original if you may need the camera information later. For a quick resize, use the Resize Image page.
Privacy and local inspection
The file is read in your browser. ImageTool24 does not upload it or collect its metadata. Any cleaned copy is generated locally and downloaded to your device.
Frequently asked questions
Does changing DPI increase image quality?
No. DPI is a print setting. To add real pixels, resize the image to larger dimensions, although that cannot recover detail that was never captured.
Can I remove GPS and camera information?
Yes. Use the remove-metadata option to create a cleaned copy without the embedded EXIF fields.
Why does my photo show the wrong orientation?
Phones often store orientation in EXIF instead of rotating the pixels. Removing metadata or re-saving through an editor can correct the display.
Is the image uploaded for analysis?
No. The details are read locally in your browser and are not sent to a server.
