Resize an Image: Set Width and Height in Pixels
An image resizer adjusts pixel dimensions for a website, document or upload form. Enter the dimensions required by the destination and review sharpness and proportions after processing.
Resize to specific pixel dimensions
- Choose an image file and note its current dimensions.
- Enter the desired output width in pixels.
- Enter the desired output height in pixels.
- Process the resize, then inspect the image at its intended display size.
- Download the new copy and compare it with the source before replacing anything.
Pixel size and aspect ratio
Width and height control the pixel canvas. If the tool does not lock the aspect ratio, entering unrelated values can stretch the subject. Choose dimensions that preserve the intended proportions.
Upscaling and image quality
Increasing pixel dimensions does not restore detail that was absent from the source. For crisp results, start with a sufficiently large original and use the target platform’s recommended dimensions.
Frequently asked questions
What dimensions should I use?
Use the pixel dimensions requested by the website, document, print workflow or upload form where the image will appear.
Does resizing reduce file size?
It may, because fewer pixels can require less data, but the final size also depends on image format and compression settings.
