Resizing is about pixels, not file size: a banner that must be exactly 1920 by 1080, a product photo that a store wants at 1000 pixels wide, a thumbnail at 300. Type the width and height you need and download the resized image.
By default the tool keeps the proportions of your picture. It fits the image inside the box you ask for, so nothing is stretched and nobody looks wider than they are. If you really need the exact width and height regardless of shape, untick the aspect-ratio option and the image is forced to those dimensions.
Making an image smaller is safe and keeps it sharp. Making it larger than the original is different: the tool can add pixels but not detail, so an enlarged photo looks softer. For that job the Image Upscaler on this site does better, and for a specific shape such as a square avatar, crop first and resize after. The resizing is done on your device and the file is never uploaded.

Frequently asked questions
- Will resizing reduce quality?
- Downscaling keeps images crisp. Upscaling past the original size can soften them.
- Does it keep the aspect ratio?
- Yes by default — the image fits inside your dimensions without stretching. Uncheck the box to force exact width and height.
- How do I resize without changing the shape of the picture?
- Leave "keep aspect ratio" on and enter only the dimension you care about most. The other side is calculated for you.
- Does resizing also make the file smaller?
- Usually, because fewer pixels mean less data. If you need a specific file size in KB, use the Compress Image tool after resizing.

- 300 DPI explained: what print shops actually want from your image DPI is a number stored in the file, not a measure of quality. What "300 DPI" really asks for, the pixel sizes that print sharp at common paper sizes, when changing the tag is enough, and when you genuinely need more pixels.
