What are the limits of Perspective Correction Tool?
PNG, JPG and WebP input, up to 20 MB and 24 megapixels. Output up to 12 megapixels using bilinear projective resampling. Choose corners clockwise from top left; concave, crossing and tiny selections are rejected. The browser decodes orientation. This corrects planar perspective, not lens distortion or curved pages. PNG preserves transparency; JPG uses white beneath transparent pixels. Processing occurs in a cancellable worker. Files and text are processed in your browser. No uploads, external font services or model calls. Nothing is saved automatically; refreshing clears the session. Downloaded files contain the content you choose to export.
