Perspective Warp - Utilities Bunker

Mesh density

Drag & drop an image here (nothing is uploaded).

Tip: Increase mesh density for higher quality (slower). 20-32 is a good balance.

Drag the four pink handles to match the document corners (TL, TR, BR, BL). The output below is re-sampled into a rectangle.

Load an image (file pick or drag-&-drop). Nothing leaves your device.
Set corners: move TL/TR/BR/BL handles to the page corners in the photo.
Mesh density: larger = finer quality, slower; smaller = faster, blockier edges.
Download exports PNG at the estimated page size (based on opposite side averages).
Heads-up: This uses a mesh of affine triangles (piecewise) to approximate projective warp-great for documents; extreme perspective may need more density.

Edge cases & tips

Very skewed photos: raise mesh to 32-48 for smoother edges.
If the photo looks rotated after load, rotate it in an external editor first (EXIF orientation isn't applied here).
Handles are clamped to image bounds; use Reset Corners to start over.
