The signature exists only in your browser and in the file you save; Bindery never has the document. If the PDF has fields, Fill forms completes them as a checklist first and Flatten locks the answers; if someone else must sign, Request signatures seals the document on your phone and lets them sign on theirs through a link, with an audit page and a trusted timestamp on completion. It is a visual signature, the everyday kind, not a cryptographic one; Certify adds that, with a key that never leaves the device. Free use covers all of it, ten completed jobs per UTC day, no account.
How it works
- Share the PDF into Bindery from Gmail, Drive or Files
- Draw with a finger or stylus, or type your signature, then tap where it belongs
- Save the signed PDF and share it back
Questions people ask
Does a stylus make a difference?
It makes drawing nicer — a stylus on the pad produces a signature much like the one on paper — but a finger works, and typing your name with a chosen style is the quickest option on a small screen. Whichever you use is kept in your browser’s signature library for reuse.
How do I send the signed file back?
Save it and share it from Bindery or from the Files app to Gmail, WhatsApp, Drive or any other app. The signed PDF is an ordinary file written on the phone; nothing was uploaded to Bindery, so there is no link to fetch it from.
Is a signature drawn on a phone legally valid?
For most everyday agreements a visible signature on the document is what the parties expect and accept. It carries no cryptographic proof; when tamper evidence or a certificate is required, use Certify, and for regulated workflows a qualified provider may be needed.
