Frequently Asked Questions

Everything you need to know about image resizing

What does changing DPI do to an image?

Changing DPI updates the metadata embedded in the image file that tells printers how densely to place dots per inch. It does not add or remove pixels — the actual image data stays the same. A higher DPI setting tells the printer to print the image at a smaller physical size but with greater detail per inch.

What DPI should I use for printing?

300 DPI is the professional standard for high-quality prints such as magazines, brochures, business cards, and photo prints. 150 DPI works for large-format prints viewed from a distance. 72–96 DPI is standard for web and screen display only.

Does changing DPI affect image quality?

No. Changing DPI only updates the metadata tag in the image file — it does not resample or alter the pixel data. Your image comes out with the exact same pixels, just with a different DPI value stored in the file.

What is the difference between 72 DPI and 300 DPI?

72 DPI is the standard resolution for web and screen images. 300 DPI is required for professional print quality. If you send a 72 DPI image to a printer, it may print at a larger physical size or appear blurry. Setting it to 300 DPI ensures the printer uses the correct density.

Which image formats are supported?

ImResizer supports JPG, JPEG, PNG, and WEBP files for DPI adjustment. You can also choose the output format independently.

Is changing image DPI free?

Yes, changing image DPI on ImResizer is completely free with no account required. No subscriptions, no watermarks, no limits.

Does this upload my image to a server?

No. All processing runs entirely in your browser using client-side technology. Your image never leaves your device.
