Don't take our word for it — turn off your Wi-Fi. Docexp keeps working. A site that runs with the network off cannot be uploading your files anywhere.
Make your file fit what the form is asking for
Exact pixel size, an exact KB range — including the minimum, which is what actually gets uploads rejected and which almost every other tool ignores. Plus 115 free tools to merge, compress, and convert PDFs, photos, and documents. All in your browser; nothing is ever uploaded.

Draw or upload a signature image and place it on a page. This adds a visual signature, not a legally-binding cryptographic signature.
Someone emails you a form, and you need it back with a signature on it. The usual dance is print, sign, scan. Instead, draw your signature with a mouse or finger (or upload a photo of one), place it on the page you want, and download the signed PDF.
How Sign a PDF works
- Choose your PDF, then pick the page you want to sign.
- Draw your signature in the box, or upload an image of one.
- Download the signed PDF — your document never leaves your device.
Good to know: This adds a visual signature — a picture of your signature on the page — not a cryptographic digital signature. It's what almost every form actually asks for, but it is NOT the same as a certificate-backed e-signature, and it won't satisfy a process that specifically requires one.
Common questions
Is this a legally binding digital signature?
It's a visual signature, not a cryptographic one. For most everyday forms that's exactly what's wanted. If a process explicitly demands a certificate-backed digital signature, this isn't that — and no browser tool can honestly claim otherwise.
Is my signature uploaded anywhere?
No. The drawing and the PDF are both processed in your browser. A signature is about as personal as a file gets, which is exactly why this one never leaves your device.
