Jak to działa
1. Upload your file
Drag and drop or choose a PDF file from your device. Everything is checked against its real file type before processing starts.
2. We process it
Your file runs through an isolated job dedicated to Zaczernij PDF, with clear progress so you always know what stage it's at.
3. Download the result
Get your finished PDF file with one click. The original upload and the result are deleted automatically afterward.
Twój plik pozostaje prywatny
Zaczernij PDF działa w izolowanym zadaniu przetwarzania. Twój przesłany plik i wygenerowany wynik są automatycznie usuwane po zakończeniu okna pobierania — nie przechowujemy kopii, a linki do pobrania są losowe, jednorazowe i mają ograniczony czas ważności.

Your file is processed in an isolated job and deleted automatically, along with the result, once your download window ends.
Actually removed. Redact PDF flattens the page to a fresh image after blacking out the area you select, so there's no hidden text layer left underneath that could be copied or extracted back out.
