Image Resizer

Resize an image to exact pixels or a percentage, right in your browser. Locks the aspect ratio by default, and nothing is ever uploaded.

How to use the Image Resizer

  1. Drop your image. Drag a file in, or click to choose one from your device.
  2. Set the size. Type a width or a height, or scale by a percentage.
  3. Download. Save the resized copy. The original file is untouched.

Frequently asked questions

Is my image uploaded to a server?
No. The file is decoded and redrawn by your own browser, and never leaves your device. You can confirm it by loading the page, disconnecting from the network, and resizing an image anyway.
Why does my resized image look soft?
Enlarging an image cannot add detail that was never captured, so any upscale is a guess spread over more pixels. Downscaling is lossless in that sense, which is why resizing down looks sharp and resizing up rarely does.
Does resizing reduce the file size?
Almost always, because there are fewer pixels to store. How much depends on the format: a photograph saved as JPEG or WebP shrinks roughly with the pixel count, while a PNG of flat colour may barely change.
Will the EXIF data survive?
No. The image is redrawn from its pixels, so camera settings, timestamps and GPS coordinates are all dropped. That is a privacy improvement for anything you are about to publish, and a loss if you needed the metadata.
