Frequently Asked Questions (FAQ)
How do I crop an image into a perfect square?
Select the '1:1 Square' aspect ratio preset on the top toolbar. The crop box will automatically constrain to equal width and height as you drag or resize it.
Can I enter exact pixel dimensions for cropping?
Yes. AllNeedTools provides synchronized numeric inputs for X Offset, Y Offset, Crop Width, and Crop Height directly below the visual canvas.
Does cropping lower the image resolution?
No. The crop is calculated against the original natural image pixels, preserving 100% of the native source clarity.
