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.

1. Open the scanner and choose Scan with camera (phone or webcam) or Import to add existing photos or a PDF.
2. Pick the mode: Document, Whiteboard, ID card or Book.
3. 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).
4. Tap a page to fine-tune: drag the corner handles to adjust the crop, choose a filter and rotate if needed.
5. 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.

Combine several PDF files into a single document, in exactly the order you want.

1. Select two or more PDF files (you can add more later with Add more).
2. Drag the file cards to change the order — the first card becomes the first pages.
3. Press Merge PDF. The merged file downloads automatically.

Options explained

Order

Files are merged from left to right, top to bottom. Drag cards to reorder.

Tips for best results

• Need only some pages of a file? Use Organize PDF after merging to delete or reorder individual pages.
• Bookmarks and form fields of the original files are not kept; the page content is.
• To merge images too, first convert them with JPG to PDF.

Split one PDF into several files, or extract the pages you need.

1. Select a PDF.
2. Choose a mode: Custom ranges, Every N pages, Each page or Pick pages.
3. Enter the ranges or number of pages.
4. Press Split PDF. Several files are downloaded together as a ZIP.

Options explained

Custom ranges

E.g. 1-3, 4-6, 7 creates three files. Tick “Merge all ranges” to put them into one file instead.

Every N pages

Cuts the document into equal parts, e.g. every 2 pages.

Each page

Creates one PDF per page.

Pick pages

E.g. 1, 3, 5-7 — saves just these pages into one new PDF.

Tips for best results

• Use an open range like 5- to mean “from page 5 to the end”.
• Page numbers always refer to the original document.

3. Add blank pages or reverse the order from the side panel.
4. Press Organize PDF.

Options explained

Blank page

Adds an empty page (same size as the previous page) at the end — drag it anywhere.

Reverse order

Flips the whole page order, handy for scans that were fed back-to-front.

Tips for best results

• On touch devices, press and drag a page to move it.
• Rotation is stored losslessly — the page content is not re-rendered.

Reduce PDF size while keeping text and vector graphics sharp. Only images are optimized, so text stays crisp and searchable.

1. Select one or more PDFs.
2. Choose a compression level.
3. Press Compress PDF and compare the before/after size on the result page.

Options explained

Extreme

Smallest file. Images are downscaled to ~110 dpi and compressed strongly. Good for email attachments.

Recommended

Best balance — images around 150 dpi, very good quality.

Less

High quality, moderate size reduction. Good for printing.

Tips for best results

• Scanned PDFs (made of photos) shrink the most — often 70–95%.
• PDFs that are mostly text are already small; they may shrink only a little.
• If the result would be larger than the original, you get the original back.

Rebuild damaged or corrupted PDF files so they open again.

1. Select the damaged PDF(s).
2. Press Repair PDF.
3. Open the repaired copy. If some pages are still missing, the original data was not recoverable.

Tips for best results

• Typical fixes: broken cross-reference tables, truncated downloads, wrong object offsets.
• Password-protected files can be repaired too; the password stays.

Make scanned PDFs and photos searchable. OCR (optical character recognition) adds an invisible text layer over the image so you can search, select and copy text.

1. Select a scanned PDF or an image.
2. Select every language used in the document (e.g. Hebrew + English).
3. Press Make searchable. The recognized text is also shown on the result page for copying.

Options explained

Languages

24 languages are available, including English, Hebrew, Arabic, Urdu, Hindi, Persian, Bengali, Russian, French, German, Spanish, Chinese, Japanese and Korean.

Skip pages that already contain text

Pages that already have real text are left as they are (faster and avoids double text).

Tips for best results

• Choose only the languages that are actually in the document — extra languages slow OCR and can reduce accuracy.
• For best results the text should be at least ~10 px high in the image (a normal phone photo of an A4 page is fine).
• Straighten and crop photos with the Scanner first for better recognition.

Quality

72 dpi for screens, 150 dpi for normal use, 300 dpi for printing.

Tips for best results
