A dedicated scanner is increasingly rare to actually own, but a phone camera does the job perfectly well for most purposes — forms, receipts, letters, ID documents — as long as the photo is taken carefully and turned into a proper PDF afterwards rather than left as a loose image.
This covers getting a clean photo and combining it into a PDF with Image to PDF.
Getting the photo right
- Light: use even daylight or overhead light. Avoid a single lamp to one side, which casts a shadow across the page.
- Angle: shoot straight down, directly above the document, not at an angle. A tilted shot distorts the page into a trapezoid shape.
- Background: place the document on a plain, contrasting surface so the edges are easy to distinguish, and so any automatic cropping in your camera app can find them.
- Focus and steadiness: tap to focus directly on the text before capturing, and hold the phone steady — a slightly blurred photo cannot be fixed afterwards.
Steps
- Lay the document flat on a plain surface in even light.
- Photograph it straight-on, filling the frame with the page.
- Crop out any background beyond the page edges, and straighten if it came out slightly tilted.
- Repeat for every page of a multi-page document, in order.
- Combine the photos into one PDF with Image to PDF.
Multi-page documents
For anything longer than a single page, consistency between shots matters more than any single photo being perfect. Keep the same distance, angle and lighting for every page so the finished document looks uniform rather than jumping between different sizes and tones from page to page. Photograph the pages in the correct order to begin with — it saves having to reorder them afterwards, though if a page does end up out of place, the pages can still be rearranged before combining them.
Common problems and how to avoid them
- Glare on glossy paper or laminated cards: tilt the light source or move to a different spot rather than shooting straight under a bright overhead light, which reflects directly back into the lens.
- Curled pages: weigh down the corners with something flat and out of frame, or flatten the document under a book for a few minutes before photographing it.
- Colour cast: photographing under a coloured light (a warm lamp, for instance) can tint the whole page yellow or orange. Daylight or a neutral white light gives the truest colours.
- Text near the edge cut off: leave a small margin of visible surface around the document itself so nothing important is right at the frame’s edge, where phone camera distortion is strongest.
After combining into a PDF
Phone photos are typically larger in file size than a real scanner’s output, since a camera captures far more resolution than a document actually needs. If the resulting PDF is larger than you would like to send or upload, run it through the PDF Compressor — a photographed document usually compresses very well, often losing 80% or more of its size with no visible difference at normal reading zoom.
Frequently asked questions
Do I need a dedicated scanning app?
No, a regular camera photo works, though many phones do have a built-in document-scanning mode that automatically detects edges and straightens the page, which can save a manual cropping step.
Can I combine photos from different sessions into one PDF?
Yes, as long as they are added to Image to PDF in the correct final order, it does not matter when each individual photo was taken.
Will the text be searchable in the final PDF?
No — a photographed page is an image, not real text, the same as a traditional scan. If you need searchable, selectable text, it would need to be recognised separately.
What if some pages are landscape and some portrait?
That is fine; each page keeps its own orientation in the combined PDF.
Is the tool free and private?
Yes. No sign-up, no watermark, and files are removed from the server automatically about an hour after processing.
