Frequently asked questions
Everything you need to know about scanning documents to PDF.
Do I need to install an app?
No. You scan the QR code and capture pages right in your phone’s browser — there is nothing to install on your phone or computer.
How many pages can I scan?
Free scans are limited to a few pages per document. Upgrade to a paid plan to combine many more pages into a single PDF.
Are my documents kept private?
Yes. Your captured images are transferred securely, used only to build the PDF and deleted automatically afterwards.
Can I upload images instead of using my phone?
Absolutely. Choose “Upload images” to build a PDF from photos already on your device — JPG, PNG, HEIC, WebP and AVIF are all supported.
What do the scan filters do?
Color keeps the original photo, Grayscale removes colour for a classic scan look, and Black & White maximises contrast for text-heavy pages and smaller files.
Which devices are supported?
Any modern smartphone and computer with a browser. It works on Android, iPhone, Windows, Mac and Linux without any setup.
