Control the capture before correcting it
Place the page on a flat, contrasting surface and use broad room light from the side. Avoid a phone shadow across the center, bright reflections on coated paper, and a patterned background that competes with the page edge. Hold the camera parallel to the sheet so all four corners are visible and text at the far edge is not compressed.
Wait for focus before capture, especially on receipts and small type. For a multi-page job, keep the same distance, orientation, and lighting. Consistent source images are easier to review than pages that jump between scale, color, and angle.
Inspect crop, perspective, and rotation
Automatic edge detection is a starting point. Zoom into every corner and check that page numbers, signatures, handwritten notes, stamps, totals, and footnotes remain inside the crop. A white page on a pale desk or a page with a dark border often needs manual correction.
Straighten strong perspective before saving, then rotate every page upright. Review tables, columns, and lines near the edge because they make skew obvious. If correction stretches letters or clips content, recapture the source instead of stacking more processing onto a weak image.
Verify content and document structure
Read the smallest important line at normal zoom. Check dates, totals, account references, names, and signatures rather than judging only the large heading. If recognized text will be used for retrieval, search for a distinctive phrase and open the page returned by the result.
Compare the exported page count with the original sheets. Confirm front and back pages, correct order, upright orientation, and the transition between sections. Open the PDF in a second viewer so the acceptance check covers the file you can share, not only the in-app preview.
Finish with a retrievable file
Use a filename that describes the date, subject, and version. Export to the destination required by the job and keep an independent copy for important records. If you enable optional sync, confirm the document appears in the Web workspace before treating the cloud copy as available.
Delete failed drafts and accidental duplicates after the trusted file is stored. Fewer clearly named copies reduce the risk of sending an incomplete version later. Sensitive material should be handled according to the recipient's requirements, not sent through an unapproved channel for convenience.
Quick checklist
- Use even light and a contrasting surface.
- Keep every meaningful mark inside the crop.
- Read the smallest important line at normal zoom.
- Match the exported page count to the source.
- Open the PDF in another viewer.
- Store one clearly named trusted version and an intentional backup.
Frequently asked questions
How do I know whether a phone scan is sharp enough?
Read the smallest line you will need later at normal viewing size. If characters merge or require extreme zoom, recapture before export.
Should I accept the automatic crop?
Only after checking all four corners and any content near the edge. Automatic crop can remove faint margins, notes, totals, or page numbers.
Why open the PDF in another app?
It verifies that page order, rotation, and readability survive export instead of existing only in the scanner preview.
