How to Resize Images
Upload your image (JPG, PNG, WebP, or any common format)
Enter new width and height in pixels
Toggle 'Maintain aspect ratio' to prevent distortion
Click 'Process' and download your resized image instantly
Key Features
Aspect Ratio Lock
Enable aspect ratio lock to automatically adjust height when you change width (or vice versa). Prevents stretching or squishing your images.
High-Quality Resampling
Uses advanced canvas interpolation algorithms for smooth, high-quality resizing. Supports both upscaling and downscaling with minimal artifacts.
No File Size Limits
Resize images of any size, from tiny thumbnails to massive high-resolution photos, limited only by your device's RAM.
Batch Processing Ready
Process one image at a time quickly. For bulk resizing, simply repeat - no daily limits or usage caps.
Privacy & Security
Your images are processed entirely client-side using JavaScript and the HTML5 Canvas API. 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.
Frequently Asked Questions
What image formats are supported?
All common formats: JPG/JPEG, PNG, WebP, AVIF... Output format matches input format (or you can convert using our format conversion tools).
Will resizing reduce image quality?
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.
What does 'maintain aspect ratio' do?
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).
Can I resize to specific file size (KB/MB) instead of dimensions?
This tool resizes by pixel dimensions only. For file size reduction, use our image compression tools (JPG Compress, PNG Compress, WebP Compress).
What's the maximum image size I can resize?
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.
Can I batch resize multiple images at once?
Currently one at a time. However, there are no limits - resize as many as you need consecutively. Each image processes in seconds.
Does resizing remove EXIF data?
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.
