Filix PDF Signer

Add your signature image to every page of a PDF — or onto a single JPG / PNG — right here in your browser. No account, no upload to any server, nothing stored.

1
Pick a mode — use the PDF / IMAGE switch at the top right to choose what you are signing.
2
Upload your file — a PDF (all pages shown) or a JPG / PNG image. Maximum size 100 MB.
3
Upload your signature as a PNG or JPG. A transparent PNG looks cleanest.
4
Place it — drag the signature anywhere, resize from the four red corners, and rotate with the gold knob above it.
5
Save — download the signed PDF, or the signed image in its original format.

Resizing page 1 updates every untouched page at once; resizing or rotating any other page affects that page only. Everything happens on your device — your files are never stored or sent anywhere.
