Frequently asked questions
Will resizing reduce image quality?
Resizing always involves some pixel resampling. We use a high-quality bilinear method, so visual loss is minimal — especially when downscaling.
Are my images uploaded to a server?
No. The Image Resizer runs entirely in your browser using a Canvas element, so your files stay on your device.
What is the maximum image size?
You are limited only by your device’s memory. Most modern phones and laptops handle 25 MP photos comfortably.
