Frequently asked questions

How many images can I merge into one PDF?

There's no hard limit; the amount depends on your device's memory. For many large images, enabling compression keeps the PDF file size manageable.

Does the scan mode make pages as straight as a real scanner?

Yes. The tool detects the document's four corners and corrects perspective, so photos taken at an angle are flattened out.

Do I need to install an app?

No. Everything runs right in your phone or computer browser — no app installation needed.
