Download a single image, or a ZIP when you resized several.
Frequently asked questions
Are the images uploaded?
Nothing is uploaded. The file is read into memory by the page and processed by your own browser, and the site’s Content Security Policy blocks outbound connections entirely — so it cannot send your file anywhere even if it tried.
Can I resize many images at once?
Yes. Add as many as you like, apply one setting to all of them, and they come back as a ZIP.
Will the aspect ratio be preserved?
Resizing by longest side or percentage always preserves it. Exact dimensions let you override it if you specifically need a fixed width and height.
Can I enlarge a small image?
You can, but nothing invents detail that was not captured. Scaling up looks soft; it is best kept to modest increases.
