Frequently asked questions
Can I resize without losing quality?
Choose PNG for lossless output. For JPEG and WebP, set quality to 90–100 to minimize quality loss.
Does the aspect ratio lock work automatically?
Yes. With the lock enabled, changing width automatically recalculates height and vice versa.
What image sizes are supported?
There is no hard limit — you can resize to any dimension your browser's Canvas API supports.
