How it works
- Drop your images
The dimensions appear next to each file.

Type a width, a height, or a percentage. With 'keep ratio' on, giving one side fills the other automatically.
- Resize and download
Everything resizes consistently, ready to download.
Questions people actually ask
How is the quality after an upscale?
Scaling up can't invent detail that wasn't there. It won't blur like a phone screenshot — Lanczos-quality resampling is used — but 2x is the practical limit.
Can I resize by exact percentage?
Yes — switch to percent mode and set 50% to halve every dimension, handy for @2x assets.
