**Understanding Image Resolution**
*Pixels per inch (PPI)* — Screen resolution. Web images: 72–96 PPI. Print: 300 PPI minimum.
*Total pixels* — Width × height. A 1920×1080 image has 2,073,600 pixels (about 2 megapixels).
*Upscaling* — Making images larger adds pixels by interpolation, reducing sharpness. For significant upscaling, use AI-based upscaling tools.
**Privacy**
All resizing is performed client-side using the HTML5 Canvas API. Your images are never sent to our servers.
