FAQ
Will resizing reduce image quality?
Downscaling with Lanczos resampling keeps images sharp. Enlarging beyond the original resolution can soften detail, which is normal for any resizer.
Are my images uploaded anywhere?
No. Every image is resized locally in your browser, so your files never leave your device.
How many images can I resize at once?
There is no fixed limit. Because everything runs on your device, the practical ceiling depends on your computer's memory.
