| Upload fails | Unsupported or damaged file or limited browser decoder | Try PNG/JPEG/WebP; verify the file opens elsewhere. |
| Image appears blank | Decode or memory error | Reload and try a smaller compatible image. |
| Magic wand selects background | Nearby colors match the overlay | Undo and lower selection tolerance or use the brush. |
| Auto-detect finds nothing | Overlay differs from detectable patterns | Draw a manual mask around the intended region. |
| Ghost outline remains | Mask missed soft or translucent edges | Expand the mask slightly and remove again. |
| Filled area is blurry | Insufficient edge texture for reconstruction | Try Balanced or a tighter selection. |
| Edges look duplicated | Large mask crossed a detailed structure | Undo and remove smaller regions sequentially. |
| Part of subject disappeared | Mask overlapped the subject | Undo and subtract unwanted selected pixels. |
| Face looks artificial | Original hidden detail is unknown | Use the original image or leave the region unaltered. |
| Scratch still visible | Thin damage was only partly marked | Brush along the remaining scratch at higher zoom. |
| High Quality is slow | Large selections require more compute | Reduce selected area or image dimensions. |
| Browser tab freezes | Large pixel buffers exceed available memory | Close other tabs and work on smaller source copies. |
| Undo seems unavailable | History may reset after certain actions or reloads | Restore the saved original and start a smaller edit. |
| Before/after mismatch | Canvas zoom or comparison mode differs | Use the same zoom and pan position. |
| Batch results inconsistent | Different images have different overlays or textures | Inspect images one by one and refine their masks. |
| ZIP download blocked | Browser blocked multiple downloads or memory use | Allow download and split batch into smaller groups. |
| JPG loses transparency | JPEG has no alpha channel | Export PNG or WebP when transparency matters. |
| Export looks compressed | Low quality or repeated lossy encoding | Use high-quality output and retain an original master. |
| Export is too large | Lossless format or oversized dimensions | Use WebP or a reasonable custom output size. |
| Image colors shift | Encoding or color profile handling differs | Review exported image in target application. |
| Offline mode fails | Required page assets were not cached | Load the tool while online first. |
| Mobile drawing is imprecise | Touch gestures and small selections interfere | Zoom in and use a smaller brush or stylus. |
| Local session disappeared | Browser data was cleared or private session ended | Use exported copies; do not rely on browser storage as backup. |
| Share button is unavailable | Device lacks the requested sharing API | Download and share the file manually. |
| HEIC image does not open | Format not supported by current browser decoder | Convert HEIC to JPG or PNG first. |
| Rights to edit are unclear | The image license or ownership is unknown | Obtain permission or use a properly licensed original. |
| No detail behind overlay | Inpainting estimates rather than retrieves pixels | Avoid claims that the filled region is authentic original content. |
