Frequently asked questions
How do I draw my signature?
Click and drag (mouse) or tap and drag (finger on mobile) in the signature box above. Make a mistake? Hit Clear and try again. The drawing is captured at full resolution.
Where will the signature appear on my PDF?
On whichever page you specify (default first), at the position you select (default bottom right). Future versions will support visual placement directly on the PDF.
Is this signature legally binding?
It is a visual signature, equivalent to printing, signing with a pen, and scanning. For legally binding e-signatures with audit trails (DocuSign-style), you need a dedicated e-signature service. For most informal needs — invoices, agreements, forms — a visual signature is widely accepted.
Will the signature be transparent over the PDF?
The signature image has a transparent background — only the ink shows on top of the page. The white canvas you draw on is just the drawing surface.
Are my files really not uploaded?
Correct. Every conversion in this tool runs in your browser using JavaScript and the local file APIs. There is no server-side processing, no file upload, no temporary storage, and no log of what you converted. You can verify this by opening your browser's network tab while converting — the only traffic is loading the page itself.
Do I need an account or to install anything?
No. Open the page, drop your file, download the result. No signup, no email, no extension, no app.
Is there a file-size limit?
Not from us. The practical limit is your device's memory — browser tabs typically handle files in the hundreds of megabytes range without issues. Very large files may take longer to process on phones than on laptops.
