Frequently asked questions
Will resizing blur my image?
Scaling down stays sharp. Scaling far above the original size cannot invent detail, so enlargements will look soft — that is true of every resizer.
Can I resize several images at once?
Yes. Add multiple files and the same dimensions are applied to each, then download them one by one.
Is the file uploaded?
No. The resize happens in a canvas element inside your browser tab.
