For private papers you don't need a scanner. A phone, good light, and a fixed routine are enough. What matters is that the scan is complete, readable, and stored safely.

In short
Scan letters as a PDF with your phone's scan function or a scan app. Make sure there is good light, all pages are included, and the text is readable. Name the file right away with the date, sender, and content, and back it up in a second place. Whether the paper can go afterwards is up to you, depending on the document.

How to make a good scan
- 1Lay the document flat on a dark, calm surface. This helps the edges be detected.
- 2Scan in daylight or under a bright lamp, without flash and without your own shadow.
- 3Use the scan function, not the normal camera. It straightens the sheet.
- 4Scan all pages, including backs and attachments with text.
- 5Check quickly: Are numbers, dates, and the small print readable?
File it correctly right away
A scan without a name is quickly lost. Name it right away following the pattern 2026-10-09_Finanzamt_Tax-notice-2025.pdf and put it in the right folder. Also add any deadline to your calendar instead of hiding it only in the file name.
Store it safely
- At least two copies in different places, for example phone and external hard drive or cloud.
- Strong passwords and two-factor login for cloud accounts.
- Device lock on your phone, because sensitive data is now stored there.
- Check regularly that the backup really works.
Frequently asked questions
Is a photo enough instead of a scan?
If you have to, yes, as long as everything is readable. But the scan function gives you straight, high-contrast pages and combines several pages into one PDF.
What resolution do I need?
For letters, the default setting of modern phones is enough. What matters is that you can read small print easily.
May I throw the paper away afterwards?
Not automatically. You should keep the original of certificates (Urkunden) and documents with evidential value. More on this in the article about originals after scanning.
