Send a secure signing link

ABX uploads only this signing copy when you choose Send. The recipient receives a secure link, and ABX records sent, viewed, and completed timestamps plus document hashes.

No signer fields placed yet.

ABX provides an activity/completion record, not identity verification or a legal-compliance certification. Keep the offline signing file option for workflows that should never upload a document.

Unlock an advanced workflow

Basic editing, self-signing, merge/split/compress, and PDF download are free. Pay only for advanced conversions or sending a document to someone else for signature.

Payment is handled by Stripe. Local editing keeps the PDF in your browser. A document is uploaded only when you intentionally use Send for Signature.

Finish your document

Privacy: merge, split, compress, editing, and self-signing run locally. Compression creates a flattened image-based PDF, so selectable/searchable text is removed.
