Document Scanner
Scan a document with your camera or a photo, straighten and crop it, apply a scan-style filter, and combine multiple pages into one PDF — all offline, all in your browser.
Works completely offline — photos never leave your device. Add as many pages as you need, then combine them into one PDF below.
About this tool
Document Scanner turns your camera or existing photos into clean, straightened scans — capture a page (or pick one from your gallery), drag the four corner handles onto the document's edges, and it's automatically de-skewed into a flat rectangle, the way a real scanner would see it. Add a scan-style filter, rotate if needed, and stack up as many pages as you like before combining them into a single PDF.
Filters: Original keeps the photo's natural color; Grayscale removes color for a cleaner, more document-like look; Black & White pushes text and background to pure black/white — best for plain text pages; Enhance boosts contrast and brightness to make faded or unevenly lit text easier to read, without fully binarizing the image.
Everything — camera capture, corner-warp cropping, filtering, and PDF assembly — happens locally in your browser; nothing is uploaded anywhere. If you navigate away with unsaved pages, this tool automatically remembers your in-progress scan session on this device and offers to resume it next time, the same way a scanning app keeps your place if you're interrupted.
