bitGateLab Scanner

bitGateLab Scanner turns your camera into a document scanner that respects your privacy: everything is processed and stored on your device. No account, no cloud, nothing uploaded to any server. It even works offline.

SMART SCANNING
• Automatic page detection with computer vision, backed by text recognition: it finds the document even when the edge barely stands out from the background.
• Live glare warning and a built-in flashlight for scanning in low light.
• Perspective correction with true proportions: the page comes out flat and straight even if the photo was tilted.
• Manual corner adjustment with a precision loupe and two-finger zoom.
• White balance slider with live preview: fix cold or warm lighting tones.
• Shadow and uneven-lighting removal (your hand, the lamp, the window).
• Selectable resolution (150–300 dpi): sharp for reading and OCR, without huge files.

IMAGE ENHANCEMENT
• Color mode: true colors, with optional one-tap shadow removal.
• Text mode: high-contrast grayscale, ideal for printing or reading.
• Live brightness and contrast, plus one-tap auto levels.
• Switch modes anytime: your edits are never lost.

EDIT LIKE A DRAWING APP
• Freehand strokes with a color palette or adjustable blur: cover balances, account numbers or personal data with your finger.
• Editable text on the document: type, move, rotate and resize with two fingers.
• Adjustable brush width and two-finger zoom while drawing, to hit small details.
• Rotate and mirror: your strokes and signatures follow along automatically.
• Multi-level undo and redo; the history is saved with each page: reopen a document days later and continue right where you left off.

SIGNATURE
• Draw your signature on screen or import it from a photo: the background is removed automatically.
• Adjust ink thickness, size, position and rotation with gestures.
• Save several signatures and reuse them in any document.

OCR AND PROFESSIONAL PDF
• On-device OCR: view and copy the recognized text; the PDF embeds it invisibly over the image so it can be searched, selected and copied.
• Whatever you blur is also removed from the PDF text layer: redaction is real.
• Import existing PDFs and edit them as if you had scanned them.
• Multi-page documents, reorderable by dragging; editable file name.
• A4, Letter, Legal, Tabloid, fit-to-document, or custom size in mm, inches or pixels.
• Built-in preview and PDF reader; share via WhatsApp, email, Drive or any other app.

PREVIOUS JOBS
• Each document is a single item with four clear actions: open, edit, share and delete.
• Edit an old job (color, signature, new pages) and its PDF updates itself: no duplicates.

REAL PRIVACY
• Your documents never leave your device.
• The PDF you share is flattened: what you covered cannot be recovered by any other program.
• Originals and edit history are stored encrypted (256-bit AES, key protected by the phone hardware) and excluded from backups.
• No account, and your documents are never used for advertising.

MORE
• 12 languages: Spanish, English, Portuguese, French, German, Italian, Russian, Chinese, Japanese, Korean, Arabic and Hindi.
• Light and dark theme; large-icon interface that also feels great on tablets.
• Every feature is free, supported by unobtrusive ads. Premium removes all ads: pay monthly, yearly, or once for life.
