Frequently asked questions
Will resizing reduce image quality?
Slight quality loss is normal when shrinking; we use high-quality resampling to keep results sharp.
Can I make an image larger?
You can upscale, but enlarging beyond the original size will look softer because no new detail can be invented.
Is the aspect ratio preserved?
Yes by default. Unlock it if you want to stretch or squash the image freely.
Are images uploaded?
No — all resizing happens locally in your browser using a canvas.
What is the maximum image size?
Limited by your device memory. Most modern phones handle 20–30 MP photos comfortably.
