Comparison
Sign PDF vs pdfFiller, for getting a contract signed
pdfFiller is a full PDF editor that also sends documents for signature. We only do the signing part, so we can be quicker and cheaper at it. If you mostly need people to sign things, here is how the two compare.
| Sign PDF | pdfFiller | |
|---|---|---|
| Cheapest plan that sends documents for signature | $5 a month (2 documents), or $10 a month unlimited | Premium, $15 per user a month at the published rate. Sending runs through signNow. |
| Billing | Monthly. Cancel from the billing page whenever you like; the plan runs to the end of the month you paid for. | Prices are advertised at the annual rate. Paying month to month costs more. |
| Placing signature, date and name boxes | Done for you. We read the document, find every blank and work out who each one belongs to. | You drag each field onto the page in the editor. |
| Trying it first | Upload a file on the home page and see the boxes placed. No account, no card. | A 30-day free trial that starts with signing up for a paid plan. |
| Word and image files | Converted to PDF on upload. | Converted to PDF on upload. |
| Signers need an account | No. | No. |
What you get with us that's easy to miss
- A certificate of completion attached to every signed PDF, listing each signer's IP address, location, device and the time of every step
- Signers confirm a six digit code sent to their email before the document opens
- The finished file is sealed with a digital signature, so any later edit shows up in Acrobat
- Anyone can check a copy at signpdf.ai/verify without logging in or uploading the file
- Signing order, automatic reminders and a decline button with a reason
When pdfFiller is the better pick
If you need to rewrite the text of a PDF, pull official forms from a large library, or manage a team of editors on one bill, pdfFiller does far more than we do. We don't edit the wording of your document. We get it signed, with a record that holds up.
Plenty of people use both: they draft and fill in pdfFiller or Word, then send the final PDF through us.
