Piles of papers, drawers full of invoices and half an hour spent looking for one document. Digitization solves all of this. A paperless office saves time, space and nerves. Let us explain how to digitize documents and what to keep in mind.

What document digitization is

Digitization means converting paper documents into electronic form and then working with them on a computer. The goal is a paperless office where documents are quickly accessible, searchable and take up no physical space.

Scanning and OCR

The basis is a quality scanner or a multifunction printer. When scanning, it pays to use OCR (text recognition), which turns a scanned image into searchable text. Thanks to this, you later find a document by its content, not just by the file name.

For ordinary documents, 300 DPI resolution is enough and a good compromise between legibility and file size. Scan to PDF rather than separate images, so a multi-page document stays in one file. For larger volumes, a scanner with an automatic document feeder (ADF) is worth it, as it takes a whole stack at once and you do not have to insert sheet by sheet. Scanning both sides (duplex) in a single pass saves a lot of work too.

Organization and naming

Scanned documents need to be sensibly organized and named, otherwise digital chaos arises instead of paper chaos. A unified folder system (for example by year, type and partner) and clear file naming rules help.

A proven name starts with the date in a format that sorts correctly and continues with the type and partner, for example 2026-06-17_invoice_supplier.pdf. With the date at the start, files sort chronologically on their own and you find a document even without searching. Agree on one format across the whole company and stick to it.

Archiving and backups

An electronic archive is only as good as its backup. Store documents in a safe place with a backup, ideally following the 3-2-1 rule. Consider encrypting sensitive documents.

A scanned paper is just a copy, not an original. If a document is to carry legal weight electronically too, use a qualified electronic signature, which under the European eIDAS regulation is equivalent to a handwritten one. You can read more about how it works and when you need it in the article on the electronic signature. For long-term archiving, also make sure files are still readable in ten years, which is why the PDF/A format, designed for exactly this, is recommended for archives.

Benefits for a company

  • Space savings, no drawers and archive rooms.
  • Fast searching of documents in seconds.
  • Access from anywhere when stored in the cloud.
  • Better protection against loss (fire, flooding) than with paper.

What to watch out for

  • Some documents must also be kept in paper form by law, check the retention periods and requirements.
  • Privacy and GDPR with documents containing personal data, related to the article on GDPR.
  • Scan quality, so documents are legible even after years.
