Upload a JPG, PNG, or WebP image by dragging it into the drop zone or clicking to browse your files. Once loaded, the tool displays the original dimensions and lets you enter a custom width and height. With "Maintain aspect ratio" checked, changing one dimension automatically calculates the other to prevent distortion. You can also use scale presets (25%, 50%, 75%, 150%, 200%) or pick a common resolution like 1920x1080 or 1280x720. Click "Resize Image" to process, then preview and download the result.
Modern cameras and smartphones produce images with resolutions far larger than most use cases require. A 12-megapixel photo might be 4000x3000 pixels, but a blog post only needs 800px wide. Resizing images to the correct dimensions reduces file size, speeds up page loads, and ensures images display at the intended size without browser scaling. Properly sized images also load faster in emails, social media posts, and messaging apps, saving bandwidth for both sender and recipient.
Aspect ratio is the proportional relationship between an image's width and height. Common ratios include 16:9 (widescreen), 4:3 (traditional), and 1:1 (square). When you maintain the aspect ratio during resizing, the image keeps its original proportions and avoids looking stretched or squished. This tool calculates the correct corresponding dimension automatically when the lock is enabled.
Will resizing reduce image quality? Scaling down generally preserves quality well. Scaling up can cause blurriness since the browser must interpolate new pixels. For best results, avoid enlarging images beyond 200% of the original.
Is my data private? Yes. This tool runs entirely in your browser using the HTML5 Canvas API. Your images are never uploaded to any server.
What format is the output? The output matches the input format. JPG images are saved as JPG, PNG as PNG, and WebP as WebP, preserving the original quality settings.
