Frequently Asked Questions
Changing image DPI means updating the image metadata that describes how densely the pixels should be placed when the image is printed. It is commonly used for print preparation, document requirements, scanning workflows, and situations where a lab, printer, or form requests a specific DPI value without changing the actual pixel dimensions of the image.
No. Changing DPI only updates metadata that affects print-size interpretation. The actual pixel data in the image stays the same, so the visible detail, resolution, and image quality on screen do not automatically change just because the DPI value changes.
It changes the physical print size guidance, not the number of pixels in the file. Lowering DPI makes the same pixels spread over a larger printed area, while raising DPI makes them print in a smaller area. The image dimensions in pixels do not change unless you separately resize the file.
300 DPI is a common standard for many professional print jobs and photo-quality prints. Around 150 DPI can be enough for larger prints that are viewed from farther away, while higher values such as 600 DPI may be used for highly detailed print workflows or certain specialized output requirements.
No. All processing happens locally in your browser, so your images never leave your device while the DPI metadata is updated and the files are downloaded. The tool does not upload your images to a remote server for processing or storage.
