Frequently asked questions
What is the recommended DPI for printing photos and documents?
300 DPI is the industry standard for high-quality printing, while 600 DPI is used for fine art and detailed archival prints.
Does changing DPI affect image file quality or size?
No, it adjusts the print density metadata so physical printers know exactly how many dots to place per inch without degrading pixels.
Can I convert images to 300 DPI for visa and passport submissions?
Yes! Many visa portals and government agencies strictly require 300 DPI images.
Are my images uploaded to the server?
No. All image adjustments occur client-side on your computer or phone.
