Image Resizer
Resize images in your browser. Set width and height, download the result as PNG. No server upload.
Upload an image, set width and height, and download a PNG. All processing stays on your device.
How to use this tool
- Choose an image file from your device.
- Enter target width and height in pixels.
- Click Resize, preview if shown, then download the PNG.
Design tips
- Upsizing small images can look soft—start from the largest source you have.
- Keep aspect ratio in mind; stretching non-square sources into a square may crop or distort depending on the tool behavior.
- For icons, consider PNG to ICO after you have a crisp square master.

FAQ
Is there a max size?
The tool caps dimensions to keep the page responsive—see on-page limits. Very large images may be slower on older devices.
Why PNG output?
PNG is lossless and widely supported for resized exports in-browser.
Will transparency work?
PNG sources with alpha typically keep transparency; JPEG does not have transparency.
