Resize photos and graphics to exact pixel dimensions or percentages with aspect ratio lock directly in your web browser.
Image resizing utilizes the browser's hardware-accelerated HTML5 Canvas 2D rendering pipeline. When dimensions are scaled down, bilinear filtering averages pixel color neighborhoods to prevent jagged edge artifacts (aliasing).
The aspect ratio lock calculates proportional dimension scaling:
Original image: 1200 × 1600 px (3:4 ratio). Setting width to 600 px automatically adjusts height to 800 px, keeping facial proportions accurate.
