Frequently Asked Questions
Should I resize by pixels or percentage?
Use pixels when a platform requires exact dimensions. Use percentage when you want proportional scaling without targeting a fixed size.
What happens if I disable aspect ratio lock?
Width and height can be adjusted independently, which may stretch or squash the image.
Will resizing reduce file size too?
Usually yes, especially when reducing dimensions. For stronger file size reduction, follow up with Compress Image.

Can I resize without losing aspect ratio?

What is the maximum output resolution?
You can resize images up to 8000x8000 pixels. For very large outputs, processing may take slightly longer.
