How to use Scan to PDF
Osd-Scan turns photos of paper into clean, straight, print-ready scans — like a dedicated scanner app. It finds the page edges, corrects the perspective with the real page proportions, removes shadows and enhances the text.
- Open the scanner and choose Scan with camera (phone or webcam) or Import to add existing photos or a PDF.
- Pick the mode: Document, Whiteboard, ID card or Book.
- Hold the camera over the page. The outline turns green when the page is steady and the photo is taken automatically (or tap the shutter).
- Tap a page to fine-tune: drag the corner handles to adjust the crop, choose a filter and rotate if needed.
- Drag pages to reorder, then choose page size, quality and optional text recognition (OCR) and press Save PDF.
Options explained
- Auto color
- Removes shadows and color casts, turns the paper white and keeps ink and stamp colors. Best for most documents.
- Light text
- Makes faint, grey or pencil text darker. Use for faded receipts and light prints.
- Grayscale
- Same cleanup as Auto color, without color. Smaller files.
- Black & white
- Pure black text on white — the smallest files and the crispest print. Not ideal for photos or signatures in color.
- Whiteboard
- Removes glare and grey background from whiteboards and boosts marker colors.
- Original
- The straightened photo without any enhancement.
- ID card mode
- Scan front and back; both sides are placed on one A4 page at real card size (85.6 × 54 mm) — perfect for forms that ask for a copy of your ID.
- Book mode
- Photograph an open book: the spread is split into left and right pages automatically.
- Recognize text (OCR)
- Adds an invisible text layer so you can search, select and copy text in the PDF. Supports 24 languages including Hebrew, Arabic, Urdu and Hindi.
Tips for best results
- Place the page on a darker, plain surface — contrast makes edge detection almost perfect.
- Use daylight or a bright room and avoid your own shadow over the page; the shadow remover handles soft shadows, not black ones.
- Hold the phone parallel to the page. Small angles are corrected automatically, extreme angles reduce sharpness.
- If the page fills the whole photo, Osd-Scan keeps the full image and only straightens the text.
- Use Auto detect in the crop screen to re-run edge detection after you moved the corners.
Questions
The crop cut off part of my page — what do I do?
Tap the page, stay on the Crop tab and drag the round corner handles (or the edge handles in the middle of each side) to the real page corners. A magnifier appears so you can place them precisely. Press Done to apply.
Can I scan multiple pages into one PDF?
Yes. Keep capturing — every photo becomes a page. You can also mix camera shots and imported photos or PDF pages, then reorder them by dragging.
Can I import a PDF into the scanner?
Yes. Each PDF page is added as a page so you can apply filters (e.g. Black & white) and export again.
Is Osd-Scan really free?
Yes. Every web tool is free with no sign-up, no watermark and no daily limit. The website is supported by ads. A paid desktop app for Windows (one-time purchase, no ads) is coming soon.
Are my files uploaded to a server?
No. All processing happens inside your browser on your own device. Your documents never leave your computer or phone, so nobody — including us — can see them. You can even disconnect from the internet after the page loads.
