Resize Images Online
Change the dimensions of any image in seconds. Set an exact width and height, or scale by percentage while keeping the aspect ratio so nothing looks stretched. All resizing happens in your browser, which means your photos stay private and the result is ready to download immediately.
Common reasons to resize
- Social media — match the recommended dimensions for profile pictures, posts and banners.
- Websites — smaller images load faster and improve Core Web Vitals.
- Email and uploads — fit attachments and forms under size limits.
- Printing — reach the pixel dimensions a print size needs.
Keep the proportions right
When you lock the aspect ratio, changing one dimension updates the other automatically, so circles stay round and faces are not squashed. Unlock it only when you deliberately need an exact, non-proportional size. Resizing down is lossless in appearance; enlarging a small image well beyond its original size can look soft because there is no extra detail to add.
Pixels versus percentage
Use pixels when a platform specifies exact dimensions, for example a 1200 by 630 social share image. Use percentage when you simply want something smaller, such as halving a photo for a faster web page. Either way the preview shows you the new size before you download.
Private and instant
Your images are processed locally and never uploaded. There is no queue, no watermark and no account. It works on phones, tablets and desktops.
