A forum wants 800 pixels wide, an email would bounce with the original and a web page does not need a 4,000-pixel photo. Resizing fixes all three.
Using the resizer
- Choose an image, up to 25 MB, in the Image Resizer.
- Pick a width: 320, 640, 800, 1,024, 1,600 or 1,920 pixels.
- Leave “keep aspect ratio” ticked so the height is calculated for you.
- Download the result.
With the aspect ratio kept, a 1,920 × 1,080 photo resized to 800 wide becomes 800 × 450. Choosing “0” keeps the original width.
Keeping the shape
Unticking the aspect ratio lets the height change independently, which distorts the picture unless you really need that. To get a different shape without stretching, crop it. Background on proportions is in the aspect ratio entry.
Size versus quality
- Shrinking an image discards pixels, which cuts the file size sharply.
- Enlarging stretches existing pixels and cannot add detail, so enlarged photos look soft.
- For the web, choose about the width the image will be displayed at, or up to twice that for sharp screens.
Frequently asked questions
Can I enter a custom width?
The tool offers set widths. For other sizes, resize to the nearest and crop or scale again.
Will it also compress the file?
Resizing reduces size mainly by reducing pixels. For further savings, use the compressor.
