Document Scan Enhancer
Fix dull, dark or tilted scans and photos of documents: boost contrast, whiten the paper background, sharpen text and rotate the page, then download a clean PNG — everything happens in your browser and your file is never uploaded.
Original
Enhanced
How to use
- Upload your scanned image or a photo of the document.
- Click Auto Enhance — contrast and paper whitening adjust automatically, or adjust the sliders yourself.
- Click Download PNG to save the clean document.
Good to know
- Press Auto Enhance first — it reads your scan and picks sensible settings automatically.
- Use the B&W / Color button to switch between grayscale (best for documents) and color.
- Paper whitening pushes light grey backgrounds to pure white for cleaner printouts.
- Your original image stays untouched — only the enhanced copy is downloaded.
