About this Resize Image tool
Profile pictures, website banners, online forms and marketplaces all ask for images of a certain size. This tool resizes images to exact pixel dimensions or by a percentage, using high-quality smoothing so results stay sharp.
Keep the aspect ratio locked to avoid stretching, or unlock it to set an exact width and height. When you resize several images with the ratio locked, each one keeps its own proportions.

Frequently asked questions
How do I resize an image without losing quality?
Making an image smaller keeps it sharp. Enlarging beyond the original size cannot add detail, so very large enlargements look soft.
How do I keep the aspect ratio?
Leave “Keep aspect ratio” ticked. When you change the width, the height updates automatically, and vice versa.
Can I resize many images to the same width?
Yes. Add all your images, choose width and height, enter the width, and each image is scaled to that width with its own height.
Which formats are supported?
JPG, PNG, WebP, GIF, BMP, AVIF and HEIC. You can keep the original format or convert while resizing.
Are my images uploaded?
No. Resizing happens in your browser.
