About Image Resizer

Image Resizer is a free, browser-based tool that lets you resize any image to exact pixel dimensions in seconds. Whether you need to prepare images for social media, optimize web graphics, or create thumbnails, this tool handles it all with precise width and height controls and an optional aspect ratio lock.

All image processing happens entirely in your browser using the HTML5 Canvas API — your photos are never uploaded to any server. Choose from popular preset sizes or enter custom dimensions, select your preferred output format (PNG, JPEG, or WebP), and adjust quality settings for the perfect balance between file size and image clarity.
