What is Resize Image?
Resize Image scales any photo to the exact dimensions you need — set precise pixel width and height, shrink or enlarge by a percentage, or pick a ready-made preset like 1080p or a square. Lock the aspect ratio to avoid stretching, choose a lossless PNG or a smaller JPEG, and watch the target size update live. Everything runs on a canvas in your browser, so your image is never uploaded.
How to use Resize Image
Add your image
Drag a PNG, JPEG, or WebP onto the drop zone, or click to browse. The tool reads its original width and height and fills them in for you.
Choose how to resize
Pick Exact pixels to type a width and height, Percentage to scale from 1% to 200%, or Preset to select a common size such as 1920x1080, a square 1080x1080, or a 320x240 thumbnail.
Keep the proportions
In Exact mode, leave Lock aspect ratio on so changing the width updates the height automatically and your image never looks squashed. Turn it off to stretch to any dimensions on purpose.
Pick an output format
Choose PNG for a lossless result with transparency, or JPEG for a smaller file with an adjustable quality slider. JPEG flattens transparent areas onto a white background.
Download the resized image
The target size is shown as you adjust settings. Click Download to save the resized image, named after your original file with a -resized suffix.
