What this tool does
- Four ways to state the size: a width, a height, a percentage, or “fit inside a square of N pixels”, which answers “no more than 2000 pixels”.
- Proportions are ALWAYS kept: when you want a square, you crop, you do not squash.
- Nothing is enlarged unless you ask: a thumbnail blown up to 2000 pixels gives a heavier file and a blurrier image.
- The resulting size is shown per image, before saving.
- Several images at once, under the same rule: a folder of photos is brought to one size in a single gesture.
What it does not do: Scaling up invents nothing: the added pixels are interpolated from the ones that exist, and the image will be blurrier, not more detailed. That is why enlargement is unticked by default. There is no AI upscaling here: it would need a model of several dozen megabytes downloaded from a third-party server, and this site downloads none.
Nothing is uploaded. Cut your network connection once this page has loaded: the tool keeps working. How to check it yourself.
