Resize images to exact dimensions or scale proportionally while preserving quality. Our free image resizer works entirely in your browser - no uploads, instant results, and complete privacy for your photos.
Enable aspect ratio lock to automatically adjust height when you change width (or vice versa). Prevents stretching or squishing your images.
Uses advanced canvas interpolation algorithms for smooth, high-quality resizing. Supports both upscaling and downscaling with minimal artifacts.
All resizing happens in your browser using HTML5 Canvas API. Your images never touch our servers - zero uploads, zero data collection.
Resize images of any size, from tiny thumbnails to massive high-resolution photos, limited only by your device's RAM.
Process one image at a time quickly. For bulk resizing, simply repeat - no daily limits or usage caps.
See original dimensions and preview new size before processing. Know exactly what you're getting.
Your images are processed entirely client-side using JavaScript and the HTML5 Canvas API. No uploads occur - verify by checking your browser's network tab. We have zero access to your photos. Since processing is local, you can even use this tool offline after the initial page load. Perfect for sensitive documents or confidential images.
All common formats: JPG/JPEG, PNG, WebP, GIF, BMP, AVIF. Output format matches input format (or you can convert using our format conversion tools).
Downscaling (making smaller) typically maintains quality well. Upscaling (making larger) will look softer since you're adding pixels. For best quality when enlarging, use AI upscaling tools instead.
When enabled, changing width automatically adjusts height (and vice versa) to keep the same proportions. Prevents distortion. When disabled, you can set any width/height independently (may stretch image).
This tool resizes by pixel dimensions only. For file size reduction, use our image compression tools (JPG Compress, PNG Compress, WebP Compress).
Limited only by your device's available RAM. Most devices handle 20-50 megapixel images easily. Very large images (100MP+) may be slow or fail on low-memory devices.
Currently one at a time. However, there are no limits - resize as many as you need consecutively. Each image processes in seconds.
Yes. Canvas-based processing strips metadata (EXIF, GPS, camera info). This is actually a privacy feature. If you need to preserve metadata, use specialized tools.
