How to resize an image without losing quality
Our resizer uses the HTML5 Canvas API to redraw your image at the target dimensions using high-quality bicubic-style interpolation. It runs entirely in your browser — nothing is uploaded to a server.
For best results when reducing size, scale down by no more than 50% at a time for images you'll print. For web use, any reduction is fine. Scaling up (enlarging) will always result in some softness — no tool can add detail that wasn't there originally.
