Why phone photos of documents look bad
Taking a picture of a contract with the default camera produces a JPG that's blown out by ceiling lights, warped by the angle you held the phone at, and shows the surface behind the page. It's the wrong shape, the wrong contrast, and not searchable. Anyone you send it to has to squint.
Email a JPG like that to an accountant and you'll get a polite request for 'a proper PDF'. The reason is real: receipt JPGs can't be indexed, can't be OCR'd by their bookkeeping software, and frequently don't pass document upload validators.
A document scanner app rebuilds the photo into what it should look like: rectangular, contrast-corrected, deskewed, and saved as a PDF with hidden text behind it. Multi-page documents become a single file, not twelve camera-roll JPGs.
Scan like it's a real scanner
Auto edge detection
The app finds the document edges automatically and snaps the scan when the framing is right.
Perspective correction
Skewed angles get straightened. The result looks shot from directly above.
Multi-page scans
Capture page after page in sequence. The app stitches them into one PDF.
OCR (searchable text)
Recognize the words inside scanned pages so the resulting PDF is searchable and copyable.
Smart filters
Color, black-and-white, or document-optimized filters to handle lighting issues.
Auto-naming
The app suggests filenames based on the document content — receipts, contracts, IDs.
How to scan a document to PDF
- 1
Open the scanner
Tap the Scan tile on the home screen of the PDF Editor app.
- 2
Aim at the document
Hold the phone roughly above the page. The app finds the edges and pulses when ready.
- 3
Let it auto-capture
Or tap manually. The capture is instant.
- 4
Adjust corners if needed
Fine-tune the detected edges before the perspective is corrected.
- 5
Add more pages
Tap the page counter to continue. The app stitches them in order.
- 6
Save as PDF
Pick a filename (or accept the auto-suggestion) and save. OCR runs in the background.
Scanning where you are
Receipts get scanned at the table, contracts at the meeting room, IDs at airport check-in. The whole point is that you don't carry a flatbed in your bag. A document scanner on your phone is the closest substitute and, for everyday business needs, completely sufficient.
Frequently asked questions
- For everyday business documents — receipts, contracts, IDs, forms — yes. For archival photo scanning or fine print on glossy paper, a flatbed is still better.
- Very reliable. The app keeps capturing until you stop, and you can reorder or delete pages before saving.
- All major Latin-script languages, plus Cyrillic, Greek, Arabic, Chinese, Japanese, Korean. Recognition quality varies by lighting and page condition.
- Yes. The app produces a clean, deskewed scan you can save or share. For security, keep ID scans in a protected folder or apply a password to the resulting PDF.
- Scanning and edge detection run on-device. OCR for some less-common languages may require a connection on first use to download the model.
