How to scan a document with your phone

No app store, no install — open this page and start scanning in seconds.

1

Photograph or drop the page

Snap a photo of the document with your phone, or drag in an existing photo or PDF from your desktop.

2

Trace the corners

Drag the four corner handles onto the page edges. The scanner perspective-crops it flat, so a photo taken at an angle still comes out straight and rectangular.

3

Clean up and save

Strip the desk or shadow behind it, pick a color mode, then download a ready-to-send PDF.

Everything a real scanner does, minus the hardware

A free, browser-based document scanner with the tools you'd expect from a dedicated scanning app.

Snap and scan instantly

Use your phone's camera right in the browser, or upload a photo you already took — either way, scanning starts in one tap.

Auto-detects page edges

Corner handles start near the page boundary so you rarely need to adjust more than a small nudge before cropping.

Perspective correction

Photos taken at an angle get squared off, not just rotated — the same fix a flatbed scanner gives you automatically.

Background and shadow removal

Cut out the desk, hand, or shadow surrounding the page, leaving a document that looks like it came off a real scanner.

Multi-page PDFs

Scan several pages in a row and combine them into a single multi-page PDF, just like scanning a stack through a real feeder.

Runs fully offline in your device

Every scan is processed locally with WebAssembly. No file is ever sent to a server, so private paperwork stays private.

No app to download

Most scanning apps ask you to install something and create an account first. This one opens in your existing browser tab — nothing to download, nothing to sign up for.

Works on any device

iPhone, Android, laptop, or tablet — as long as it has a camera or a photo to upload, it can scan a document here.

Your documents never leave your device

Because processing runs client-side, there's no upload step for anyone to intercept. That matters for IDs, contracts, and anything else you'd rather not put on a server.

What people scan here

Anywhere you'd reach for a scanner app, this page does the job for free.

Forms and applications

Scan a filled-out form on the spot instead of hunting for a physical scanner at the last minute.

Receipts for expense reports

Turn a crumpled paper receipt into a flat, legible PDF page you can attach to an expense claim.

IDs and cards

Scan a driver's license, passport page, or membership card when a form asks for a digital copy.

Signed contracts

Capture a paper contract right after signing, straighten it, and send a clean PDF the same day.

Notes and whiteboards

Photograph handwritten notes or a whiteboard and crop away everything but the content itself.

Mail and paperwork on the go

Scan a letter or bill the moment it arrives, without waiting until you're near a physical scanner.

More scanning tools

Free, private, and browser-based — just like the scanner above.

Loved by renters, bookkeepers & coordinators

Thousands of people clean up a scanned document here every day. Here's what a few of them say.

My phone scan of a lease was crooked with a shadow across it. Two minutes here and it looked like it came off a real scanner.
Alicia R. · Tenant
Switching to black & white made an old faded receipt scan actually readable again — and it never left my laptop.
Devon P. · Bookkeeper
I clean the scan, then compress it to 200KB for the portal. Two tools, zero uploads, done in under a minute.
Farah N. · HR Coordinator

Frequently asked questions

Do I need to install an app to scan a document?

No. This document scanner runs entirely in your mobile or desktop browser. Open the page, use your camera or upload a photo, and you're scanning — no install, no account.

Is my scanned document uploaded anywhere?

No. Every step — cropping, background removal, color mode — happens locally on your device using WebAssembly. Your file is never sent to a server, so sensitive documents stay private.

Can I scan more than one page into a single PDF?

Yes. Add each page as you go and the tool combines them into one multi-page PDF, so a multi-page contract or packet stays together in one file.

What if my photo of the document is at an angle?

Drag the four corner handles onto the actual page edges. The scanner perspective-crops the image to a flat rectangle, correcting angled or skewed shots the same way a physical scanner would.

Is this document scanner really free?

Yes — completely free, with no signup, no watermark, and no limit on how many pages or documents you scan.

Does it work as well as a phone scanning app?

For everyday documents like forms, receipts, and contracts, yes. You get corner correction, background cleanup, and color modes without installing anything extra on your phone.
