| Mode | Buttons | Perspective pulls artwork shot at an angle back to square using four corner handles. Straighten just rotates a scan that is tilted but not skewed. PerspectiveStraighten |
| Corner Handles | Buttons | Perspective mode only. Drag the four handles onto the real corners of the artwork; the cyan guide quad shows the area that gets flattened. Top-leftTop-rightBottom-rightBottom-left |
When to Use
- Straightening a phone photo of a fabric swatch or print
- Flattening a scan that came out skewed or keystoned
- Squaring up artwork before vectorising or tiling
- Recovering a usable flat file from an angled reference shot
Pro Tips
A sharp, evenly-lit photo with all four corners visible gives the cleanest result
Place each handle exactly on the artwork's corner — anything outside the quad is dropped
Flatten first, then run the result through the AI Image Upscaler if you need more resolution
Use the before/after slider to confirm the correction before downloading
What to Expect

Real-World Examples
Swatch Photo
A phone photo of a tilted fabric swatch was corrected by marking its four corners, producing a straight rectangular file for tracing.
Skewed Scan
A keystoned scan of a hand-painted motif was flattened into a clean rectangle, ready to vectorise.
