Nothing is uploaded: the signature exists only in your browser and in the file you download, and Bindery never has the document. If the PDF has fillable 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 Chromebook and lets them sign on their own device through a link. It is a visual signature — the everyday kind — not a cryptographic one; Certify adds that, with a key generated in the browser that cannot be exported.
How it works
- Open Bindery in Chrome and drop the PDF into Sign
- Draw on the touchscreen or trackpad, or type your signature, and tap where it belongs
- Download the signed PDF
Questions people ask
Does a touchscreen Chromebook make a difference?
It makes drawing nicer — a finger or a stylus on the pad produces a natural signature — but it is not required. On a Chromebook without touch, draw with the trackpad or type your name and pick a style; placement works with a click either way.
Can students sign permission forms this way?
Yes, and nothing they sign is sent to Bindery, which keeps the job on the device and out of any upload policy. For a form with fields, fill them first; for a scanned form without fields, Markup adds text where the blanks are and Sign adds the signature.
Is a drawn signature enough?
For everyday paperwork, a visible signature on the document is what people expect and accept. It carries no cryptographic proof; when a counterparty needs evidence the file has not changed since signing, Certify adds a real digital signature verifiable in any reader, with the key kept on the device.
