Crop, straighten and correct perspective — one unified toolkit
Crop, straighten, flip/rotate, keystone correction and lens distortion, all built on a single mathematical model so every tool composes correctly with every other.
Guided Upright
Draw reference lines and the app solves the correction.
Auto Upright
One click — detects architectural lines itself, with guardrails.
Lens-ready architecture
The same model a lens-profile system needs.
Full geometry toolkit
Crop, straighten, flip/rotate, keystone and lens distortion — unified as one projective + radial model.
Guided Upright
Draw lines on things that should be vertical or horizontal, and pxlmonk solves the correction automatically.
Auto Upright
One click: edge and line detection straightens the shot, with built-in guardrails so it declines rather than guesses wrong on non-architectural scenes.
Built for what’s next
The distortion model is ready for Lensfun-style lens profiles as an additive step, not a rewrite.
