Resize any image to exact pixel dimensions or by percentage, with an aspect-ratio lock so it never distorts — processed entirely in your browser.
How it works
- Upload the image you want to resize.
- Enter your target width and height in pixels, or scale by a percentage.
- Ensure the aspect ratio lock is enabled to prevent distortion, then download the resized image.
Frequently asked questions
Will resizing reduce the visual quality?
Downscaling (making it smaller) looks crisp. Upscaling beyond the original size cannot magically add detail, so it may look soft.
Are my personal images uploaded?
No. Resizing happens locally on your device's processor. Nothing is ever sent to a server.
Why does the output always come out as PNG?
PNG is lossless, meaning the resizing process itself adds zero compression artifacts. You can use our Image Converter afterward if you need a JPG.
