How to Resize Images Online
Change image dimensions instantly — specify pixels, percentage, or choose a preset size.
Upload Your Images
Drag and drop image files onto the upload area or click Browse. JPEG, PNG, and WebP are supported in any resolution.
Set New Dimensions
Enter a width and height in pixels, or set a percentage to scale proportionally. Enable "Lock Aspect Ratio" to prevent distortion.
Click Resize
The tool resizes all uploaded images to your specified dimensions using high-quality downsampling. No quality is lost beyond what the resize requires.
Download Resized Images
Download all resized images at once. Each file is saved with the original name plus dimensions added, so originals aren't overwritten.
Why Resize Images?
From social media posts to web pages, every platform has its own optimal image dimensions.
Social Media Ready
Resize to exact platform specs: 1080×1080 for Instagram, 1200×630 for Facebook, 1500×500 for Twitter banners — in seconds.
Faster Page Loads
Serving images at their display size (instead of scaling in CSS) dramatically reduces bandwidth and improves Core Web Vitals scores.
Email & Upload Limits
Many platforms cap image uploads at 2MB or 5MB. Resizing large photos down before uploading is the fastest way to meet those limits.
Fully Private
All resizing happens locally in your browser. Your photos are never uploaded to a server — complete privacy, always.
Frequently Asked Questions
Scaling an image down is generally lossless in perceived quality if you keep the aspect ratio. Scaling up (enlarging) will make the image appear blurry since no new pixel data is added. For best results, always resize from a large original.
Enable the "Lock Aspect Ratio" option and only specify one dimension (width or height). The tool will calculate the other dimension automatically to preserve the original proportions.
Yes — after resizing, run your images through our Image Compressor to further reduce file size. Or Crop Image to trim unwanted areas before resizing.
