What is DPI and why does it matter?

DPI stands for dots per inch. It determines the print quality of an image — higher DPI means sharper prints. 72 DPI is standard for screens, while 300 DPI is the standard for high-quality printing.

Does changing DPI change the image quality?

Changing DPI only modifies the metadata that tells printers how large to print the image. It does not add or remove pixels, so the actual image data stays the same.

What DPI should I use for printing?

For high-quality prints, use 300 DPI. For draft or large-format prints like posters, 150-200 DPI is usually sufficient. For professional or commercial printing, 600 DPI may be required.

What DPI is best for web images?

72 DPI is the standard for web and screen display. Since monitors display images by pixel count rather than physical size, higher DPI offers no visual benefit on screen.

Is my image uploaded to a server?

No. The entire conversion happens in your browser using JavaScript. Your image never leaves your device.

What image formats are supported?

You can upload PNG, JPG/JPEG, WebP, BMP, and TIFF images. PNG and JPG files retain their format on download; other formats are converted to PNG.

Can I set a custom DPI value?

Yes. Besides the preset buttons (72, 96, 150, 200, 300, 600), you can type any custom DPI value from 1 to 9999 in the custom input field.

How do I check the current DPI of my image?

Simply upload your image to this tool. It automatically reads and displays the current DPI from the file metadata for PNG and JPEG files.
