Shrink or enlarge your images to the dimensions you need, keeping the proportions. Several at once, and nothing uploaded.
No sign-up and nothing uploaded to a server: everything happens in your browser. See for yourself.
No. Everything is processed inside your browser, and your files never leave your device.
Select them together and choose "By width" (or height): they'll all end up with that value and keep their original proportions.
We don't set any limits. You can process several files at once; the maximum depends on your device's memory.
Resizing is useful for preparing images for social media, online stores, documents or emails. When you enter only the width or the height, the other dimension is calculated so the image isn't distorted.
With "Exact dimensions," the image is fitted to the pixels you enter, even if its proportions change.
Shrinking an image almost always gives a good result; enlarging it a lot causes a loss of sharpness because detail can't be invented.
