Resize image dimensions online for free. Lock aspect ratio, adjust width and height in pixels, and export high-quality JPG, PNG, or WebP images instantly.
Click "Select Image" or drag and drop any JPG, PNG, or WebP file into the upload zone.
Enter your target pixel dimensions or choose a quick percentage preset (25%, 50%, 75%, 100%). Keep "Lock Aspect Ratio" checked to preserve proportions.
Keep the original format or convert your resized image to JPG, PNG, or WebP.
Click "Process Image Resizer", compare original vs resized preview, and click "Download Result Image".
When 'Lock Aspect Ratio' is enabled, changing the width automatically updates the height proportionally (and vice versa), preventing distortion.
No. All resizing, aspect ratio calculation, and format conversions happen 100% locally in your web browser using HTML5 Canvas. Your photos never leave your device.
You can upload JPG, PNG, and WebP images. You can export the resized result in its original format or convert to JPG, PNG, or WebP.
