Sign where the document already is
A document arrives somewhere: a Drive folder, an Outlook attachment, a spreadsheet a colleague keeps updating. The signing has to happen without moving your whole workflow somewhere else, and usually without installing anything, because the machine it has to happen on is frequently one you are not allowed to install on.
Drop your document here and sign it now. PDF, Word and Excel all work: a .docx or .xlsx is laid out in your browser exactly as it was written, so there is nothing to convert first. Add a signature, a date, a company stamp or a watermark, then download it sealed. Free to start, no account, and the file is never uploaded to open it.
These pages say what actually works with each, including where we have no add-on and you do not need one.
- Google Workspace, Sign a Google Doc or Google Sheet without installing a Workspace add-on or granting access to your Drive. Download, sign, and put the signed copy back.
- Microsoft Word, Sign a .docx without a Word plugin, an Office 365 licence, or converting the file first. The document is laid out exactly as written, then signed and sealed.
- Microsoft Excel, Digitally sign an Excel workbook or sign off a sheet without a plugin. The sheet is laid out the way Excel prints it, then signed and sealed.
- Outlook and Gmail, Sign an email attachment and send it back, with no add-in, no mailbox permission, and no cloud connection to your email.
- Zapier, Connect signing to the rest of your stack with Zapier webhooks and the REST API: send for signature when a form is submitted, file the sealed PDF when it comes back.
- Chromebook and Android, Sign a document on a Chromebook or an Android phone in the browser, with no extension, no Play Store download and no Android app sideloaded.
Building it into your own product
The REST API and outbound webhooks are included on the Business plan rather than sold as an add-on. There is a page for each stack, with working code.
