About the Scan to PDF tool
Scan to PDF crops the page, corrects perspective and boosts contrast so a quick photo looks like it came from a real scanner, then bundles the pages into one document.
Turn photos of paper documents taken with your phone or camera into a clean, well-aligned PDF. It is a fast way to digitize receipts, forms, and letters without a dedicated scanner.
How to convert a photo scan into a PDF
- 1Upload one or more photos of the document pages you want to scan.
- 2Let the tool automatically crop and straighten each page.
- 3Download the finished pages as a single, ready-to-share PDF.
Getting clean results from phone photos
Photos taken at an angle or with background clutter around the paper are automatically cropped and deskewed so the final PDF looks like a proper scan rather than a casual snapshot. This works best when the document is photographed under even lighting and lies flat, since heavy shadows or strong glare can make it harder to detect the page edges accurately.
Combining several page photos into one PDF keeps the whole document together instead of leaving separate image files, which is especially handy for multi-page forms or receipts. The tool does not need an account and deletes uploaded photos from the server after the PDF is generated, with all transfers protected by encryption. Output file size depends on the number of pages and the resolution of your original photos.

Frequently asked questions
Do I need to crop the photo myself before uploading?+
No, the tool detects the document edges automatically and crops out the background, though photographing the page against a plain, contrasting surface improves the result.
Will a crooked photo be straightened automatically?+
Yes, the deskew step rotates and aligns the page so text runs horizontally even if the original photo was taken at an angle.
Can I combine several page photos into one PDF?+
Yes, you can upload multiple photos and they will be arranged in order as sequential pages of a single PDF document.
What lighting conditions give the best scan quality?+
Even, diffuse lighting without strong shadows or glare produces the sharpest results, since harsh lighting can obscure text and confuse edge detection.
Can I reorder the pages after uploading photos?+
Yes, you can arrange the uploaded photos into the correct page order before generating the final PDF.
Will text in the scanned PDF be searchable?+
The scan-to-PDF conversion focuses on cropping and cleaning up the image; for a searchable text layer, run the resulting PDF through the OCR tool afterward.
