Set pixel dimensions, lock the aspect ratio, and choose how the image fills the new size. Free and instant.
Select a JPG, PNG, or WebP image. Your current dimensions are detected automatically.
Enter a new width and height. Lock the aspect ratio so the image never gets distorted.
Choose a resize mode and output format, then download your perfectly sized image.
Fit scales the image to stay within the target dimensions while maintaining its aspect ratio — empty areas are filled with white. Fill scales the image to cover the full target area, cropping any overflow. Stretch ignores the aspect ratio and stretches to exactly the dimensions you set.
When the lock is on, changing the width automatically recalculates the height (and vice versa) to preserve the original proportions. Toggle the lock off to set width and height independently.
JPEG, WebP, and PNG. JPEG and WebP support a quality slider for fine-tuning the file size vs. quality tradeoff. PNG is always lossless.
The input file limit is 20 MB. Very large output dimensions (e.g. 10000 × 10000) may be slow since all processing happens in your browser.
