| My board is missing after reopening | The browser profile, site storage or browsing mode may have changed. | Check the original browser and profile, review any JSON backups and avoid clearing site data before exporting. |
| Autosave does not seem to work | Storage permissions, quota, private browsing or a browser error may interfere. | Check available site storage and browser settings, try a small test board and export JSON while your work is still accessible. |
| The page does not work offline | Required app files might not have been cached on the device. | Open and test the app while connected, then try offline editing before depending on it. |
| A drawing is slow or laggy | Too many objects or large images may exhaust device resources. | Reduce image sizes, close heavy tabs, split complex diagrams and keep a backup. |
| A connector points to the wrong shape | The line may need its attachment or node positions adjusted. | Select the affected connector or endpoints and inspect links after moving nodes. |
| Shapes do not align | Grid snapping may be off or objects may have different anchor positions. | Enable grid and snap, zoom in and align bounding boxes deliberately. |
| I cannot select an object | A covering layer, locked group or active drawing tool may block selection. | Switch to selection mode, inspect layers and unlock any relevant items. |
| A background image keeps moving | The image is not locked or selected together with other objects. | Lock the image or place it behind other items before drawing. |
| Text appears tiny in exported PDF | A very large canvas may have been scaled to a small page. | Reorganize the content into a printable region and inspect the PDF at actual print size. |
| PNG export looks blurry | Raster resolution may be low for the intended display size. | Choose an appropriate image resolution or use SVG/PDF where suitable. |
| SVG looks different in another program | Font support, vector rendering or embedded image handling may differ. | Open the export in the destination application and correct fonts or use a PDF/image fallback. |
| JSON will not open as a picture | JSON is an editable board-data backup, not an image format. | Import JSON through the whiteboard, or export PNG, JPG, SVG or PDF for viewing. |
| JSON import fails | The file may not be a compatible or complete whiteboard export. | Use a valid JSON file exported by this tool and keep an untouched backup copy. |
| The whiteboard cannot be edited by multiple people | Real-time multi-user collaboration is not currently available. | Use one editor with screen sharing or exchange exports for asynchronous feedback. |
| Touch drawing moves the page instead | A browser gesture or current canvas tool may control panning. | Select the pen and verify touch settings; try the documented pan gesture for navigation. |
| My stylus pressure is ignored | Pressure data depends on device and browser input support. | Check hardware/browser compatibility and use manual stroke width controls if needed. |
| I deleted a shape accidentally | An active selection or delete shortcut may have removed it. | Use undo immediately; restore a JSON backup if the change is no longer in history. |
| I cannot find a saved board on my phone | Local storage is tied to device and browser, not synchronized online. | Export JSON on the original device and import it in the phone browser. |
| Dark mode makes some colors hard to read | Certain drawing colors may not contrast against the chosen background. | Adjust text and stroke colors and verify the output after changing themes. |
| An image import fails | The source image, file size or browser permissions may be unsupported. | Try a smaller compatible image and confirm local file access permissions. |
| The template is not the layout I need | Templates are generic starting structures. | Edit, move and relabel elements, or start from a blank canvas. |
| A large image covers all notes | The image may be in a foreground layer. | Send the image backward and lock it before adding notes. |
| The entire board is cut off in export | The export region may not include every distant object. | Check canvas bounds and preview the output; reposition or group distant content if necessary. |
| I need a shared edit link | This single-user whiteboard does not expose live collaborative board sessions. | Share a PDF/image for review or send JSON for sequential editing with backups. |
