How do I use dpi calculator?
Choose JPG, PNG, WebP, AVIF, HEIC from your device, adjust the available settings, review the result and download a new copy. Each source image can be up to 50 MB; large dimensions may exceed your device's memory limits.
Does changing DPI improve image quality?
No. Effective DPI is the number of image pixels divided by print size in inches. A 1800-pixel-wide image printed at 6 inches is 300 DPI. The calculator measures print resolution; it does not add image detail.
Is this tool free, and do I need an account?
The local image tools are free and do not require an account. Images are processed in your browser. An account is only needed for supported cloud-saved workflow features; model downloads still require internet access.
