How to Use the Image Resizer
- Upload an image by clicking the box or dragging a file onto it.
- Enter your desired Width and/or Height in pixels.
- Keep Lock aspect ratio checked to avoid distorting the image, or uncheck it for an exact custom size.
- Click Download Resized Image to save the result as a PNG.
How It Works
The tool draws your original image onto an HTML5 canvas at the new dimensions you specify, then exports that canvas as a PNG file. This all happens instantly inside your browser using your device's own processing power, with no upload involved.
Frequently Asked Questions
Will resizing to a larger size reduce quality? Enlarging an image beyond its original resolution can make it look slightly softer, since no new detail is created — this is a general limitation of resizing, not specific to this tool.
What format is the output? The resized image downloads as a PNG file to preserve maximum quality and transparency where applicable.
