About Image Resizer

  1. 1Click the upload area and select an image from your device.
  2. 2Edit the width and height fields to your target pixel dimensions.
  3. 3Click 'Resize' to process the image.
  4. 4Click the download button to save your resized PNG image.

Frequently Asked Questions

What image formats does Image Resizer support?

It accepts common formats your browser can open, such as JPG, PNG, and WebP. The output is always a PNG file.

Is there a limit to how large an image I can resize?

There's no fixed size limit — processing happens locally in your browser, so it's limited only by your device's available memory.

Does it have preset sizes for Instagram, Twitter, or Facebook?

No, there are no built-in presets — you enter the exact width and height in pixels yourself.

Do you store my images after I resize them?

No, Image Resizer processes everything locally and never uploads your file to a server.

Tips & Tricks

  • ✓There's no aspect-ratio lock, so calculate proportional dimensions yourself if you want to avoid stretching or squashing the image.
  • ✓For common social sizes, enter the target dimensions manually — for example 1080x1080 for a square Instagram post.
  • ✓Resizing to smaller dimensions reduces the pixel count but the output is still saved as an uncompressed PNG, which may be larger than the original file.
  • ✓Resize one image at a time — there's no batch or queue feature.
