Contracts, forms, approvals — signing a PDF shouldn't require printing it. iFiles lets you draw your signature once, keeps it in a private signature library on your device, and lets you drag, pinch and place it exactly where it belongs — on any page, even several at once. The signature is rendered into the PDF itself, so it looks right in every reader.
Open Tools → Sign PDF and choose the document.
Draw with your finger — or tap one you saved earlier. Black or blue ink.
Drag and pinch the signature into position, tap Place, then Sign & Save. The signed copy lands in your files.

Yes. Signatures you draw are stored in a private library on your device, so next time it's one tap.
Yes. The signature is rendered into the page itself — it shows up in any PDF reader, on any device.
