No. The scanner runs entirely in your browser using the device camera API. No download or app install required — works on phones, tablets, and desktops.

Original keeps the image unchanged. Enhanced boosts brightness, contrast, and saturation slightly. Document applies high contrast optimized for scanned text.

Yes. Click the sun icon on any page thumbnail to open the per-page adjust panel. Each page gets independent brightness (30–200%) and contrast (30–200%) controls with live preview. You can also select a specific filter for each page individually.

The Document filter applies high contrast and reduced saturation, making it ideal for text-heavy documents like contracts, letters, and forms. It makes printed text sharper and easier to read, similar to a flatbed scanner output.

Board mode is optimized for whiteboard and flipchart photos. It significantly boosts brightness to whiten the background, increases contrast for marker strokes, and reduces saturation to minimize glare and color casts.

When enabled, OCR (Optical Character Recognition) extracts text from your scanned images and embeds it invisibly behind the page images. This makes the PDF text selectable, searchable, and copy-pasteable — just like a native digital document.

13+ languages: English, Hindi, French, German, Spanish, Portuguese, Italian, Chinese (Simplified and Traditional), Japanese, Korean, Arabic, and Russian. Auto-detect is available for documents with mixed or unknown languages.

Yes. It uses your phone's camera directly in the browser — works on iOS Safari and Android Chrome with full filter, rotation, reordering, and per-page adjustment support.

Image processing (filters, brightness, contrast, rotation) happens 100% locally in your browser. If you enable Searchable PDF (OCR), the generated PDF is sent to our server for text extraction, then immediately deleted after processing.

When Auto-enhance is enabled, all new camera captures and uploaded images automatically get the Document filter applied. This saves time when scanning multi-page documents — you don't have to set the filter for each page manually.

Yes. Click the copy icon on any page thumbnail to create an exact duplicate (including its filter and brightness/contrast settings) placed right after the original. Useful for including the same page in different sections.

Yes. Add as many pages as you need — there is no file count limit. Add pages via camera or upload, then drag to reorder before creating your PDF.
