Frequently Asked Questions
Is my file uploaded to any server?
No, not one byte. The PDF is read and modified entirely inside your browser, and your signature is drawn on a pad right in the page — everything stays on your device and never leaves it, unlike cloud signing services that upload the document to their servers.
Can I sign on any page of the file?
Yes. Once the file is uploaded, pick the page number from the list and the signature is placed on the displayed page. You can move it anywhere on that page and drag it by its four corners to resize it before exporting.
How do I draw my signature?
Draw with your mouse or your finger on the white drawing pad. You can wipe it and start over at any time with the "Clear" button. The final signature is yours alone — we use no ready-made fonts and generate nothing on your behalf.
Does the signature stay crisp and transparent over the text?
Yes. The signature is exported as a high-quality transparent PNG, so it never hides the text beneath it and renders sharp and clean in any PDF reader.
What about its size — can I adjust it?
You can drag the signature by its corners to enlarge or shrink it before pressing "Sign". Its proportions are preserved so it is never distorted, and the tool guarantees it never crosses the page boundaries.
