Resize images
Scale images to an exact width or height, with an aspect-ratio lock so nothing comes out stretched.
Image Tools
Crop a photo with a draggable box, fixed aspect ratios and exact pixel values - in your browser.
Your files and text are processed on your own device, inside this page. Nothing is uploaded to Dubinity or stored, and closing the tab discards it. How privacy works
Drag the crop box, pull a corner, or drag across the picture to draw a new selection. Lock it to a ratio (1:1, 4:5, 16:9, a custom one) or type exact pixel values, and nudge it with the arrow keys.
The crop is a straight pixel copy, so nothing is resampled or re-compressed unless you ask for a specific output width. JPG, PNG, WebP, GIF, BMP, AVIF, HEIC and TIFF can be opened; the result saves as PNG, JPG or WebP.
