FAQ
Common questions
What is photo perspective correction?
Photo perspective correction adjusts the shape of an image when it was taken from an angle. It can help straighten document photos, signs, interiors, and buildings that look tilted or skewed.
Can I fix a document photo taken at an angle?
Yes. Upload the photo, use Distort / Lens Correction to adjust vertical or horizontal perspective, then crop or resize before export.
Can I straighten a building photo online?
Yes. Vertical perspective correction can reduce the leaning-building effect caused by shooting upward. Strong correction may create blank corners, so Scale or Auto crop may be needed.
Is this the same as crop or rotate?
No. Rotate changes the angle of the whole image. Crop cuts the image area. Perspective correction changes the image geometry to reduce skew and perspective distortion.
