Signing PDFs
With the PDF Center you can sign any PDF — delivery note, handover protocol, contract, an externally received invoice — and hand it over in two clicks. Signatures are managed centrally and shared with Quick Invoice.
The 5-step flow
- Open the PDF. Click Select PDF and pick the file — on the web you can also drag the PDF into the window.
- Pick the page. A thumbnail strip at the bottom shows every page. Tap the page you want to sign.
- Insert a signature. Tap the pen icon at the top.
- Pick a saved signature from the list, or
- tap Draw new signature, enter name and role, draw on the screen. Tick Save for later if you want to reuse it.
- Place and adjust. The signature appears as a green box on the page. Drag it with your finger or mouse to the right spot and use the zoom icons to resize.
- Save. Tap Save signed PDF. The file is downloaded immediately (web) or opened in the share sheet (mobile).
Sign multiple pages
You can place a separate signature on every page of the document — for example on each page of a multi-page contract. Tap a different page in the strip and start over from step 3. Already signed pages show a small check mark in the strip.
Remove a placed signature
As long as you haven’t saved yet, you can remove the placed signature on the current page with the trash icon. After that you can switch to a different page or insert a new signature.
Drag & drop on the web
On the web you can simply drag the PDF onto the “Open PDF for signing” area. A green border appears while dragging — release to open. No file-picker dialog needed.
What happens to the original?
The opened PDF stays unchanged on your device. The signed PDF is downloaded as a
new file prefixed with signed- — e.g. contract.pdf becomes signed-contract.pdf.
Connection to Quick Invoice
The saved signatures used in the PDF Center are the same as in Quick Invoice. A signature drawn in the PDF Center and saved for later is available the next time you sign an invoice — and vice versa.
