Image Resizer — Resize Images to Exact Pixels (Free)

Upload an image, set width and height, and download a PNG. All processing stays on your device.

How to use this tool

1. Choose an image file from your device.
2. Enter target width and height in pixels.
3. 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.
