Why Image Quality Matters
In the digital landscape, your images are your first impression. When you resize an image, most online tools compress the file on their servers, often resulting in "pixelation" or "artifacts." At RefineDoc, we use client-side algorithms that prioritize edge-preservation and color accuracy.
100% Local Processing
Unlike other tools, RefineDoc resizes your images directly in your browser. Your sensitive documents never leave your computer, and no data is ever uploaded to our servers.
Mastering Aspect Ratios
Understanding aspect ratio is the key to preventing "stretched" or "squashed" photos. For example, a 1:1 ratio is a perfect square, while 16:9 is the standard for widescreen video.
