Frequently Asked Questions

Is SahajPatra Online Whiteboard completely free and private?

Yes. No account or signup is needed. All drawings, uploaded images, and multi-page boards are processed and autosaved locally on your device via browser storage, so drawings remain on your device. Browser storage may be cleared; keep a project backup.

Can I use a graphics tablet, Apple Pencil, or stylus?

Yes! Our engine uses native HTML5 Pointer Events with real-time pressure sensitivity, palm-friendly touch gestures, two-finger pinch zoom, and spline stroke smoothing.

What happens if I accidentally close my browser tab?

SahajPatra automatically saves every stroke and page locally in real time. Reopening the page restores the last successfully saved board, and you can also save portable .sahajboard files.

Can I export my notes as a printable PDF or transparent PNG?

Click Export in the top bar to download high-resolution PNG (with optional transparent background), JPG, Vector SVG, or a multi-page PDF document.
