Image Resizer
Resize an image to a specified width and height.
Overview
- Resizes an image to a specified width and height.
- With "Keep aspect ratio" enabled, entering either the width or height automatically calculates the other.
- Unlike Image Converter, this resizes to the exact dimensions you specify (including enlarging), not just as an upper bound for shrinking.
Usage
- Drag and drop an image, or click to select one.
- Enter the desired size into "Width (px)" and "Height (px)".
- With "Keep aspect ratio" enabled, entering one value automatically calculates the other.
- Click "Resize" and download the result.
Example
Input
Original: 1920x1080, width: 1280 (aspect ratio kept)
Output
Resized to 1280x720
Use Cases
- Resizing an image to a specific pixel size for a social media post or blog
- Matching images to a fixed size for use in documents or slides
- Enlarging a small image for use as an icon or thumbnail
FAQ
How is this different from Image Converter?
Image Converter is primarily for format conversion, and its resizing only shrinks images to fit within a "max width/height". Image Resizer specializes in resizing to the exact dimensions you specify, including enlarging.
What happens if I enlarge an image?
Specifying a size larger than the original will enlarge it, but the extra detail beyond the original resolution is generated by interpolation, so the image may look less sharp.
Can I choose the output format?
No, you cannot choose it. The image is exported in the same format as the uploaded file (PNG, JPEG, or WebP). Unsupported formats are exported as PNG.
Notes
- Processing runs entirely in your browser; uploaded images are never sent to an external server.
