About this tool

Resize any image to exact pixel dimensions while maintaining quality. Our Image Resizer uses the HTML5 Canvas API with high-quality bicubic interpolation for smooth downscaling. Upload PNG, JPG, WebP, or GIF images and resize them to custom dimensions or use built-in presets for social media platforms: Instagram (1080×1080), Twitter (1200×675), Facebook (1200×630), YouTube thumbnails (1280×720), and more. The tool supports aspect ratio locking to prevent distortion, percentage-based resizing (50%, 25%), and output format selection (PNG for lossless, JPG for photos, WebP for smallest file size). Adjust output quality from 10% to 100% to balance file size and visual quality. All image processing happens entirely in your browser using the Canvas API — your images are never uploaded to any server, making it safe for sensitive or private photos.
