Frequently Asked Questions

Will resizing distort my image?

Not if "Lock aspect ratio" stays checked — changing width automatically adjusts height proportionally, and vice versa.

What preset sizes are available?

Full HD (1920×1080), HD (1280×720), Instagram square (1080×1080), 800×600, and a 400×400 thumbnail size.

Can I resize by percentage instead of exact pixels?

Yes, switch to "By percentage" mode and use the slider — 50% halves both dimensions, 200% doubles them.

What image formats are supported?

JPG, PNG, and WebP — the output keeps the same format as your original file.
