Frequently asked questions
Will resizing distort my image?
Not if you keep "Lock aspect ratio" checked — width and height will scale together proportionally.
Can I make an image larger, not just smaller?
Yes — enter dimensions larger than the original, though enlarging beyond the source resolution may reduce sharpness.
Does this work for both JPG and PNG?
Yes — the output keeps the same format as your uploaded image.
