Turn document photos into readable pages without losing faint details
Scan to PDF applies a scan appearance to JPG or PNG photographs and creates one PDF page per image. Assemble receipts, handwritten notes or photographed forms in order. The tool does not control a desktop scanner or automatically reconstruct a flat sheet.
Capture all four document corners under even light, keeping the camera parallel to the page. Filters change tone and contrast; they cannot recover blurred letters, straighten perspective or restore missing corners.
Choose settings based on the information you must preserve
| Your situation | Recommended approach |
|---|---|
| A colour stamp, annotation or chart matters | Use Original colour. Grayscale and black-and-white discard colour distinctions that may change how the document is interpreted. |
| Dark printed text on a reasonably even page | Try Enhanced grayscale first. Check small text and pencil marks before using the stronger High-contrast black & white option. |
| A document must print on standard paper | Choose A4 or US Letter and a suitable orientation. The whole photo is fitted inside the margin; extra white space can remain when the proportions differ. |
| The output should follow the photo's proportions | Choose Fit each image. It sets page dimensions from each image and disables the separate paper-orientation choice. |
Compare a grayscale scan with the original-colour version
Try document-photo.png, a synthetic 1200 × 800 example. It helps explain the controls but cannot predict filter quality on a real shadowed photograph.
- Add document-photo.png. Choose A4, Paper orientation Landscape, Margin 8 mm and Rotate photos Keep upright.
- Select Enhanced grayscale and Image quality Balanced, then choose Create scanned PDF and download the result.
- Reset the result, change only Scan appearance to Original colour, and create a second PDF. Keep the two downloads distinguishable when comparing them.
- Open both PDFs at the same zoom. Compare small lettering, light areas and coloured details; choose the appearance that preserves required information.
Expected result. Each run produces a one-page landscape A4 PDF with the photo fitted within the chosen margin. The grayscale version removes colour; neither version automatically crops to paper edges, corrects perspective or adds a searchable text layer.
Check the downloaded result
- Count the photos and output pages. Arrange photos with the move-up and move-down controls, then check the PDF's page order.
- Zoom into handwritten digits, dates, totals, stamps and faint lines. Reject a filter that makes the paper look cleaner at the expense of required information.
- Check all corners, orientation and the amount of whitespace. Rotate photos applies the selected angle to the batch, so prepare mixed-orientation photographs consistently before one conversion.
- Inspect a print preview when needed. Image quality changes JPEG encoding; it cannot increase the detail captured by the camera.
Troubleshooting
- Faint handwriting disappears in black-and-white mode
High-contrast conversion pushes tones toward black or white. Light strokes can become white even when they were visible in the photograph.
Try this: Return to Enhanced grayscale or Original colour and recreate the PDF. If the source is poorly lit, take another photograph rather than relying on a stronger filter.
- The page is trapezoidal, shadowed or surrounded by a desk
There is no automatic edge detection, perspective correction or document crop in this tool. The full photo is placed on the PDF page.
Try this: Retake the photo parallel to the sheet under even light. Crop unwanted surroundings in an image editor before importing the image again.
- A phone photo is rejected or the camera option is missing
This conversion accepts JPG and PNG. The device and browser determine how their file picker exposes camera capture, and a photo library may supply HEIC instead.
Try this: Export the photograph as JPG or PNG and add it from the gallery. On a desktop, transfer a supported image first; opening this page does not guarantee a camera capture interface.
- The batch exceeds a limit or stalls on large photos
The tool limits combined file bytes, image count and decoded-image memory according to the device. Several high-resolution photos can exhaust memory despite modest file sizes.
Try this: Check the current limits beside the picker, reduce image dimensions where readability allows, or convert smaller groups and merge the reviewed results.
Limits and compatibility
- Image PDF, not OCR
- The result contains raster page images. Searching or copying photographed words requires a separate OCR step, and recognized text must be checked against the image.
- Originals and local processing
- Photos are processed in the browser and encoded into the output PDF; source image metadata is omitted by the conversion. Keep the original photographs so you can change filters later without repeatedly recompressing an earlier scan.
Your files and form values are processed on this device. Downloaded copies remain wherever you save them. See how to check local processing and our privacy policy for site data and optional services.
Common questions
- Does choosing High quality make blurry writing readable?
- No. It reduces additional encoding loss relative to a lower-quality export, but cannot restore detail absent from the source photograph. Retake an unreadable photo before creating the PDF.
- Why was the same image not added twice?
- The picker deduplicates files with the same name, size and last-modified value. Check the displayed list rather than assuming every repeated selection will add another output page.
