What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
Limited capabilities on iPad. Would be nice to have drawing tools on iPad. Also can't copy and paste between two forms, so if you need to have the same info on two forms, it's somewhat cumbersome. That said, not bad for the price.

I think it's very useful but expensive and the basic subscription does not seem adequate to perform some of the things needed at that initial level for that cost.

Love the service and how it integrates with Zapier - it has saved me tons of time in manual repetition for filling out intake, invoicing and legal documents and I love the send to sign feature. Would like a little more functionality in the app, like having the ability to sign docs directly instead of using mobile browser, but overall it functions beautifully. Best value for this type of service hands-down. As a small business, the price-point is phenomenal! Highly recommend PDFfiller!!

Can I sign a document online?
Absolutely. pdfFiller allows you to sign any document using our Division technology. You can use a signature font or upload a signature file and apply it anywhere on the document.
What is a digital signature?
A digital signature is the process to authorize a digital message or document with a certificate-based digital ID. A valid digital signature means the identification of a signer has been verified. Digital signatures are most often used to apply a digital “seal” to an electronic document in order to make it tamper-evident.
How does pdfFiller verify electronic signature?
pdfFiller can offer an audit trail to show by whom and when the signature is created. With pdfFiller's new feature “Signature Verification”, you can get instant signature verification and sign your file digitally and securely. pdfFiller will work as a trusted third party, or a certificate authority (CA). When you and your client draw, upload or capture a signature, pdfFiller will instantly provide a digital certificate to validate your electronic signature. With pdfFiller's cloud technology, you can also get a digital certificate when accessing and working on your PDF files from an iPad, iPhone and other mobile device.
What's the difference between an electronic signature and a digital signature?
An electronic signature can be any piece of data like an image, a symbol, a sound recording and others. You can create an electronic signature skimpily by typing your name or uploading an image.

Can I upload a signature from my computer?
Yes. Click on the “Signature” button in “Editor” page to upload, draw, type or capture your digital signatures. Once you're done with creating your signatures, click “Save” and drag your signature anywhere within the document to use.
Do I need to upload a signature every time?
