Resize an image online
Change pixel dimensions to fit a form, listing, or platform’s size limit.
Most upload forms, marketplaces, and platforms enforce a size limit or a specific dimension — and photos straight off a phone or camera rarely match. Resize lets you set exact pixel dimensions or scale by a percentage, with aspect ratio locked by default so nothing looks stretched.
How to resize image
- Drop a JPG, PNG, WebP or HEIC image into the upload area — maximum 50 MB.
- Choose "By pixels" for an exact width/height, or "By percentage" to scale proportionally.
- Toggle "Keep aspect ratio" on or off as needed.
- Click "Resize image" and download the result.
Common use cases
- Fit a photo to a form or ID upload’s required dimensions.
- Shrink a camera photo before attaching it to an email.
- Prepare a product photo for a marketplace listing’s size limit.
- Scale a batch of images down for a faster-loading web page.
