Get LiteFrequently asked questions
Does my PDF get uploaded when I sign it?+
No. The free signer runs entirely in your browser and your document is never transmitted. An automated network test fails our build if the signer ever sends a document anywhere.
How do I sign a PDF without uploading it?+
Open the free signer, load your PDF or image (it stays local), create your signature by drawing, typing, or photo, drag it into place, and download the flattened PDF.
Is it really free?+
Yes. The in-browser signer is free to use with no account, supported by ads. Paid plans exist for teams and workflows, not for basic signing.
Is a signature made this way legally valid?+
It produces a simple electronic signature (SES), which is suitable for many everyday agreements. For documents with strict form requirements, check the rules that apply to your case.
What file types can I sign?+
PDF, PNG, and JPEG. Images are converted into a single-page PDF before signing.
Can I sign documents offline?+
Yes. Sign Simplified Lite is a one-time €49 download, the entire signer in a single file that runs on your computer with no internet at all.
What proof do I get when someone signs my document?+
On paid plans, every request-to-sign records each event, link opened, consent given, signature applied, in a tamper-evident, hash-chained audit log, and signatures are applied by the server, so a signer's device can never alter or replace the document content. When everyone has signed, all parties receive a certificate of completion by email with timestamps, signer emails, IP addresses, and the document's SHA-256 fingerprint.
