How it works
Upload a JPG, PNG, WebP, or GIF image, choose new dimensions or a scale percentage, and download the resized file. Aspect ratio can be locked, and you can keep the original format or export as JPG, PNG, or WebP. Resizing runs entirely in your browser—files are not uploaded to a server.
Limitations
Upscaling cannot recover detail that was not in the original image. Extreme aspect-ratio changes may crop or distort if not constrained.
Privacy and file handling
Your data is processed in your browser and is not uploaded to our server.
