How to resize an image
- Add your image above. It's processed in your browser — nothing is uploaded.
- Enter the width and height you want in pixels, or pick a preset like 1920×1080 or an Instagram size. Keep the aspect-ratio lock on to avoid stretching.
- Download the resized image. Use a preset page to start with the dimensions already filled in.
About resizing images
Resizing changes an image's pixel dimensions — how wide and tall it is — which also affects its file size. Making an image smaller is essentially lossless, since it simply has fewer pixels; enlarging it past its original size can look soft, because the browser has to invent detail that isn't there.
Common reasons to resize: fitting a photo to a website banner or profile picture, meeting an exact upload requirement such as a 600×600 avatar, or shrinking a huge camera photo before sharing. Ready-made presets cover standard resolutions and the latest social-media sizes.
Resizing and compressing work well together: reduce the dimensions first to cut most of the file size, then compress to hit an exact KB target. Everything runs locally, so your images stay private.
Frequently asked questions
How do I resize an image to exact dimensions?
Type the width and height in pixels (or choose a preset) and download. With the aspect-ratio lock on, changing one dimension updates the other so the image isn't stretched.
Will resizing make my image blurry?
Making an image smaller stays crisp. Enlarging beyond the original size can look soft because the extra pixels are interpolated — start from the highest-resolution original you have for the best result.
Can I resize for Instagram, YouTube or other platforms?
Yes — pick a social-media preset for the exact recommended size, or enter custom dimensions for any platform.
Are my images uploaded to resize them?
No. Resizing happens entirely in your browser, so your images never leave your device and nothing is stored online.
