Use your phone camera (or upload existing photos) to capture document pages, apply a scan-style filter — grayscale, black & white, or whiteboard — and stitch every page into a single multi-page PDF. Tap to add the next page; download when done.
01 — What you create
Capture pages with your phone camera (or upload from the gallery), apply a scan-style filter — grayscale, black & white, or whiteboard — and stitch them into one multi-page PDF. The filter applies live; reorder pages before exporting.

02 — How it works
Most "scanner" apps want a signup and an account. This tool gives you the same outcome — capture pages, apply a scan filter, stitch into a PDF — from the browser, with no upload and no account. Works on a phone with the rear camera; works on a laptop with uploaded images.
On phones, tap "Open camera" to capture each page with the rear camera. On desktop, upload from your gallery or scanner output folder. Add as many pages as you need.
Colour (preserve source), grayscale (smaller file), black & white (crisp document text), or whiteboard (boost brightness + contrast). The thumbnails update live.
One click stitches every captured page into a single multi-page PDF at your chosen page size and quality. Reorder, drop pages, or change the filter before exporting.
03 — Built for fast scans
On mobile, the "Open camera" button launches the rear camera straight away (via the file input's capture hint). One tap per page; no app install.
Colour (preserve source), grayscale (smaller, archive-friendly), black & white (crisp text, ~70% smaller), whiteboard (boosted contrast + brightness for darker captures).
Thumbnails re-render with the chosen filter the moment you switch. No guessing whether B&W will eat the receipt header or boost it.
Up / down arrows on each thumbnail rearrange page order before export. Remove accidental captures with one click.
Each captured page picks portrait or landscape based on its dimensions. A4 / Letter / A5 / or fit-to-image page sizes.
Camera capture, filtering, and PDF assembly all run locally via canvas + jsPDF. No upload, no third-party scanner API, no account.

04 — Common questions
No special permission. The "Open camera" button triggers a standard file input with a camera capture hint — mobile OS handles the permission prompt the same as any photo upload. Nothing runs in the background; the camera opens only when you tap.
No — this tool produces image-based scans (each page is a photo embedded in the PDF). Text isn't selectable in the output. For OCR (searchable scans), you'll need a follow-up step — the pdfFiller premium tier handles that, or any desktop PDF editor with OCR.
Black & white is the right default for document text — crispens letters and shrinks the file dramatically (often 70%+ vs colour). Whiteboard is for darker captures where the source needs brightness lift. Grayscale is a middle ground. Colour preserves photos / illustrations that need to stay in colour.
Depends on filter + page count. A 6-page B&W scan typically lands around 1 MB; a 6-page colour scan more like 4–6 MB. Use the Compress Invoice PDFs tool afterwards if you need to email a large scan packet.
Not in this tool — it captures and filters but does not auto-detect document edges or correct perspective. For deskew + auto-crop, look at native scanner apps (Adobe Scan, Microsoft Lens, Apple Notes scanner). Once you have a clean scan, drop it into Sonchoy's PDF utilities for merging, compressing, or rotating.
Never. Captured images, applied filters, and the assembled PDF all stay on your machine. The browser triggers the download via the standard mechanism. No upload, no third-party scanner API, no logging.
