Concepts & tips

Adding files

There are three ways: drag files into the dashed box, click the box to pick them, or import them with the cloud buttons. Tools like Merge accept as many files as you want at once.

Importing from Dropbox and Google Drive

Below every upload area you'll find buttons for Google Drive and Dropbox. The file goes straight from your cloud to you, never through us. The first time you import from Google, Google asks for your permission once. The picker always shows your own account.

Where your file is processed

The key thing to know: with 73 of our 107 tools, your file stays on your device and never leaves it. With the rest, such as Office conversions, OCR and compression, it's encrypted in transit, processed in Germany for your conversion only and deleted right after. Each tool page tells you which applies.

Preview and control

Almost every tool shows you what will happen before it happens: thumbnails when merging, a live preview when rotating, highlighted matches when redacting, traffic-light reports in the checking tools. Take advantage of that, especially before printing and with sensitive documents.

Installing as an app

In Chrome and Edge, an "Install app" button appears in the header. It gives Gatefrog its own icon on your desktop or Start menu and opens it in its own window. On iPhone, tap Share → "Add to Home Screen".

Troubleshooting

Very large PDFs are mostly limited by your device's memory. An up-to-date browser and a bit of patience help, and a progress bar shows how far along it is. Web optimization loads its engine once, the first time you use it (a few seconds). After that it's fast. Password-protected PDFs need to be opened with the Unlock tool first. And to text tools, scanned documents are just images, so run OCR text recognition on them first.

Privacy in brief

No registration, no tracking, no analytics cookies. Details are in our privacy policy (in German), and our step-by-step guide to safely redacting sensitive documents is in German, too.

For legal information, see Legal & privacy (in German).
