Quick answer
To resize an image, add it to the KitFuse image resizer, enter a new width or height in pixels (or a percentage) and keep the aspect ratio locked. For an exact size, pick a preset such as Instagram post 1080 × 1080; the image is filled and cropped to fit. Download one image or all of them as a ZIP.

Keep proportions or crop to fit
With Keep aspect ratio on, enter only a width or a height and the other side is calculated for you, so nothing is stretched. When you need an exact width and height, switch it off and choose what happens if the shape differs: fit inside keeps the whole picture, fill and crop trims the edges for a perfect fit, and stretch distorts the image to match. KitFuse resizes in several smooth steps for sharper results than a single jump, and saves images without metadata. To shrink file size as well, try the image compressor.
Frequently asked questions
Can I resize several images at once?
Yes. Add up to 100 images and they're all resized with the same settings. Download them together as a ZIP.
Will resizing make my image blurry?
Making an image smaller keeps it sharp. Making it much larger than the original can look soft, because the extra pixels have to be invented.
Which format are resized images saved in?
By default the original format is kept. You can also choose JPG, PNG or WebP under Output format.
Is it private?
Yes. Images are resized in your browser and never uploaded.
