Frequently Asked Questions
Is my data sent to a server?
No. All image processing happens directly in your browser. Your
images are never uploaded to any server.
What's the difference between pixels vs percentage?
Pixels give you exact dimensions (e.g., 800x600). Percentage
scales proportionally (e.g., 50% makes the image half the original size). Use pixels
for precise sizes, percentage for quick scaling.
Will resizing affect image quality?
Reducing image size generally maintains good quality. Enlarging
images can cause pixelation and blur. For best results, start with high-resolution
images and avoid scaling up more than 150%.
