Frequently asked questions
Which is the best free app for scanning documents?
Adobe Scan is the best free app: thanks to Adobe's technology it delivers the best image quality and excellent OCR (it turns the text into editable text), it is free and it adds no watermarks. It only requires a free Adobe account. If you want full privacy without creating an account, Genius Scan is an excellent alternative.
What is OCR and what is it for when scanning?
OCR (optical character recognition) is the technology that detects the text inside a scanned document and turns it into real text: editable, copyable and searchable. Thanks to OCR you can, for example, search for a word inside a scanned PDF or copy the text from an invoice. Adobe Scan and CamScanner have the best OCR, with support for many languages.
Are documents scanned with a phone legally valid?
For most everyday paperwork (emailing an invoice, a receipt or a signed contract), a good PDF scan is perfectly valid and accepted. For official procedures that require a certified copy or an advanced electronic signature, you may need an extra step. Apps like Adobe Scan produce professional-quality PDFs that work for the vast majority of uses.
