About the Image Resizer

Resize any image to exact pixel dimensions right in your browser. Set the width and height you need, keep or unlock the aspect ratio, and download the result — your image is never uploaded to a server.

Different platforms demand different sizes and reject anything else. Government and job portals specify exact photo and signature dimensions. Instagram wants 1080×1080 square posts, YouTube thumbnails 1280×720, LinkedIn banners 1584×396. Websites need images sized to their display area so pages load fast — serving a 4000px photo inside a 400px slot wastes bandwidth and hurts Core Web Vitals.

Keep the aspect ratio locked unless you specifically want to stretch the image; unlocking it distorts faces and text. Resizing down always looks clean; enlarging a small image cannot invent detail and will look soft. To hit a specific file size in KB rather than pixel dimensions, use our image compressor instead.

Aspect ratio is the width-to-height proportion. Keep it locked to avoid stretching or squashing; unlock only when a platform demands an exact non-proportional size.
No — resizing happens inside your browser, so personal photos and documents never leave your device.
Use our image compressor, which targets a specific KB size (20 KB, 50 KB, 100 KB) rather than pixel dimensions.
