Frequently Asked Questions
Will resizing reduce image quality?
Scaling down rarely causes a visible quality loss. Scaling up will soften the image since pixels are interpolated. For JPG/WebP output, you can control compression quality with the slider.
Are my images uploaded to a server?
No. Everything runs locally in your browser using the HTML5 Canvas API. Your images never leave your device.
What is the maximum image size supported?
There is no hard limit. Very large images (e.g. 50 MP+) may be slow to process on low-end devices due to browser memory limits.
What does locking the aspect ratio do?
When locked, changing the width automatically recalculates the height to keep the same proportions as the original, preventing stretching or squishing.
