📐 Image Resizer

Our tool uses advanced HTML5 Canvas technology to resize your images directly in your browser. Your images never leave your device, ensuring complete privacy and security. The resizing maintains high quality with advanced smoothing algorithms.

The aspect ratio lock (🔒) keeps the width and height proportional. When enabled, changing one dimension automatically adjusts the other to maintain the original image proportions. This prevents distortion and keeps your images looking natural.

Contain: Fits the entire image inside the target dimensions with padding (background color fills empty space).
Cover: Fills the entire target area, cropping edges if needed (no empty space).
Stretch: Distorts the image to exactly match target dimensions (may change proportions).

JPG: Best for photographs, smallest file size, supports quality compression.
PNG: Best for graphics/logos with transparency, lossless quality, larger files.
WebP: Modern format with best compression, supports transparency, widely supported by modern browsers.

We provide pre-configured dimensions for popular platforms like Instagram (posts & stories), Facebook, Twitter, YouTube thumbnails, and more. Just click a preset to instantly apply the optimal dimensions for that platform.
