Frequently Asked Questions

PDFs are hard to edit, but it doesn’t mean you cannot do so. Given the right tool, you can send PDFs for signature requests and have your signers sign them without the lengthy process of decoding or conversion. With Fill, you can quickly affix signatures into any PDF file.

Here’s what you need to do:

  1. Log in to the Fill app or Web dashboard. For new users, you can start by signing up for a free account which you can later upgrade to a paid monthly or yearly subscription.
  2. Click +Start Now and specify who’s going to sign your document. Select You & Others or Only Others to send your PDF to multiple recipients.
  3. Upload your PDF document. On Fill for Web, you can quickly drag and drop from your local folder. You can also combine up to 5 PDF files into a single document as long as the total file size won’t exceed the limit of 25MB.
  4. Assign signers and set your desired signing order. You can assign multiple signers while keeping other stakeholders in the loop via carbon copy.
  5. Edit the PDF and add at least one required signature field for each signer. Click Send, and you’re done.

When sending PDF for signature request, we recommend adding a maximum of 20 signers. Exceeding this number isn’t ideal as it’ll make your document appear too crowded. You also won’t be able to provide enough space for each signature field. Not only will this leave your signers confused, but it could also cause discrepancies and errors.

Please note that you can no longer change the signing order after a request for signature has done. It is considered final. We strongly advise you to review your request before clicking the send button. You can also pre-fill some sections to minimize completion time.

With Fill, you can either add multiple signers to a single document or bulk send your documents to a single recipient. It’s an effortless way to get your documents signed. You can also make the most out of your time. You can automate tasks, so there’s no need to repeat each step for every signature request.

Our e-signature tool also supports guided signing. The moment your signer views the request, our intuitive tool will immediately guide your signer throughout the entire signing process. It’ll also save the trouble of assisting your signers in person.

Absolutely. Your signer does not need a Fill account to complete your signature request. As long as you’re requesting signature through Fill, you can effortlessly get your documents signed. You can even send your requests via email or direct link. Your signer will then receive a notification asking to fulfill the request on or before the specified date and time.

If your signer fails to review the request, Fill will send an automated reminder. With our e-signing tool, you can skip the manual process of sending and scheduling reminders. You can also keep track of your requests via in-app notifications and email alerts.

Once received, all your signer needs to do is view the document by clicking the open button. It will then redirect your signer to Fill’s default document viewer. From there, our app will guide your signer accordingly, and once the signing process is complete, you’ll immediately get notified, leaving no room for delays and missed deadlines.

Your signer will also receive a copy of the signed PDF together with the audit log and certificate of completion. This way, you can preserve data integrity by ensuring that each signed document is unique. You can also use these details to determine whether someone has modified the PDF without your knowledge and permission.

Yes, tracking the documents you’ve sent when requesting signatures is possible. The thing is, you’ll need an e-signature service that is capable of doing so. With Fill, you can track and record the status of your signing requests in real-time. The entire process is automated. There’s no need to enter each activity manually.

On Fill’s dashboard, you’ll see that each document has its corresponding progress bar and status tags. From there, you can quickly determine whether the request has been completed or if it’s still waiting for the signer’s approval.

By checking the logs, you’ll also know whether the signer has fulfilled the requested signature on time, according to the agreed deadline. You can also check whether someone has gained unauthorized access to your document by looking at the logged IP addresses and location.
With Fill, you’re confident that your business can meet and maintain compliance. Aside from providing a reliable and convenient tool for sending e-signature requests, we also use the highest level of encryption to keep your sensitive documents safe from malicious attacks.

With our real-time tracking feature, you can quickly detect suspicious activities and prevent damages that could lead to data and financial loss. You can also ask signers to verify their identities to avoid fraudulent transactions.
