Image Resizer Online

Resize photos and graphics to the dimensions your project needs. Enter pixels, use a percentage or choose a preset, then check the new width and height before downloading.

  • Set width and height in pixels
  • Keep proportions with aspect-ratio locking
  • Resize by percentage or preset dimensions

Resize to a required width

Choose an image and enter the target width. With aspect ratio locked, the height follows the original proportions instead of stretching the subject.

Scale a whole image evenly

A percentage changes both dimensions together. For example, 50% turns a 2000 × 1000 image into 1000 × 500 pixels.

Choose resize or crop

Resizing changes pixel dimensions without selecting a new composition. Use Image Cropper first when a target shape would otherwise stretch the image or include unwanted edges.

Set realistic enlargement expectations

Increasing dimensions adds pixels through browser resampling; it cannot reconstruct missing detail. Inspect small text and edges before using an enlarged image.

Image Resizer FAQs

Aspect-ratio locking keeps the original width-to-height relationship. Unlock it only when deliberate stretching is acceptable.
No. Dimensions, output format and encoding all affect byte size. Use Image Compressor when the upload limit is measured in KB or MB.
Keep the aspect ratio locked and set the width to 1000 pixels. The matching height is 500 pixels. You can also select 50% scaling. If you need a square instead, crop to a square before resizing so the subject is not stretched.
