How does the scanner enhance whiteboard photos?

Photos of lecture whiteboards captured from the classroom often suffer from poor lighting, glare, or off-angle skew. This tool lets you crop out classroom borders, rotate pages, and apply contrast-boosting filters that isolate writing ink, making it easy to read whiteboard notes on small screens.

Can I convert photos of handwritten homework for submissions?

Yes. Many instructors require homework to be submitted as a clean PDF scan rather than multiple phone JPEGs. This tool merges all your note pages in sequence, crops margins, and compile them into a professional-looking PDF submission.

Are my classroom whiteboard photos and homework sketches private?

Yes. The scanner operates 100% locally in your web browser tab. No images are uploaded to any external database or cloud server, ensuring your schoolwork remains completely private.

Does this tool extract text from whiteboard images?

This scanner compiles and contrast-boosts the visual notes. If you need to convert the hand-written or printed text into editable text characters, use our Image to Text OCR tool.
