Change the dimensions of your images quickly and easily.
Resizing an image changes its pixel dimensions while preserving aspect ratio or allowing custom width×height. Whether you need a specific resolution for a website, a certain size for a print layout, or a smaller image for faster loading, resizing is the first step.
Social media managers resize photos to the exact pixel dimensions required by each platform. Web developers resize thumbnails and hero images to fit their layout grid. E-commerce sellers resize product images to meet marketplace requirements. Designers prepare assets at multiple resolutions for responsive sites.
Enter target dimensions in pixels or a percentage scale. Choose whether to maintain aspect ratio or stretch to fit. Our tool resizes instantly in the browser using the canvas API — no server upload, no watermark, no size limit.
Your files never leave your browser. No account required, no server uploads — just fast, local processing. This is what it means to resize images without uploading.
Define exactly what width and height you need.
Images are processed directly in your browser using Canvas technology.
Supports JPG, PNG, and WebP.
Resize the image to smaller dimensions (while keeping the aspect ratio) instead of cropping. Then download the resized image; if you still need a smaller KB size, use Compress Image.
Making an image smaller usually retains quality, but enlarging an image past its original size may cause pixelation.
Make sure the "Lock aspect ratio" option feels natural, or only adjust the width and let the height adjust automatically.
