Question 1

What if I unlock the aspect ratio?

Accepted Answer

Tap the lock icon to set width and height independently. Be careful — the image will stretch and people or objects will look distorted.

Question 2

Which resampling algorithm does it use?

Accepted Answer

High-quality Lanczos via Pica. Sharper than the standard canvas resize, especially for faces and text.

Question 3

Does upscaling lose quality?

Accepted Answer

Upscaling can never beat the original. Try to keep upscales within 30–50%, or rely on the original instead.

Question 4

Can I resize by percentage?

Accepted Answer

Currently only pixel input. To halve the image, set width to half the original — height auto-follows when the lock is on.
