In short: pdfFiller is airSlate's online PDF editor for filling in, editing, converting and sharing PDF documents and forms from a browser or mobile app. Basic covers editing, form filling, page changes and conversion to Word; Plus adds reusable templates, fillable fields, version history, password protection and hosted forms. Both are licensed per user.
What pdfFiller is
pdfFiller is a web-based PDF editor from airSlate. Instead of installing desktop software, users upload or open a PDF in the browser and fill it in, type over it, add or remove pages, highlight or erase content and send it on. It also includes an online library of fillable forms, and on Plus users can add fillable fields to a flat PDF and turn it into a reusable template.
A desktop app for macOS is available on both editions, and Plus adds the iOS and Android apps. Documents are stored in the user's pdfFiller account so they can be picked up again from any device.

airSlate also sells a pdfFiller Premium edition that bundles signNow e-signatures and US Legal Forms; we do not supply it. If signing is the main need, a separate signNow licence for the people who send documents is often the better route.
How it is licensed
pdfFiller is licensed per user. Each person who edits, fills or manages documents needs a licence on Basic or Plus, and you can mix editions if only some staff need templates and password protection.
| Option | Term |
|---|---|
| pdfFiller Basic | Monthly or annual |
| pdfFiller Plus | Monthly or annual |
| Trial | Available for either edition before you buy |
Monthly billing gives flexibility for short projects; annual billing suits teams whose numbers are steady. Upgrading from Basic to Plus mid-term is handled as a change to the subscription. Prices depend on edition, term and user count, so ask us for a quote.
Requirements and deployment
pdfFiller runs in a modern web browser, so there is nothing to deploy for most users. The macOS desktop app and the mobile apps on Plus are optional. pdfFiller states it is GDPR compliant, SOC 2 Type II certified and PCI DSS certified, which helps with supplier due diligence.
Setting up is quick: we create the accounts, set up shared folders or templates on Plus, and show staff how to fill and send documents. If you rely on Microsoft 365, users can keep files there and open them in pdfFiller when needed.
Who it suits and how we help
pdfFiller Basic suits staff who fill in and edit PDFs occasionally: HR forms, supplier forms, applications and returns. Plus suits teams who reuse the same documents, need password protection for sensitive files, or want to publish a fillable form online for customers to complete.
Forever Systems helps you choose the edition per user, supplies it on monthly or annual terms, and handles changes and renewals on one invoice. Comparing desktop PDF editors? See Foxit PDF Editor and Nitro PDF Pro.

Contact usFrequently asked questions
Is pdfFiller an online PDF editor?
Yes. pdfFiller runs in the browser, with an optional macOS desktop app and, on Plus, iOS and Android apps, so users can edit and fill PDFs without installing a desktop PDF editor.
What is the difference between pdfFiller Basic and Plus?
Basic covers editing, form filling, page changes and conversion to Word. Plus adds reusable templates, fillable fields, version history, password protection, hosted online forms and the mobile apps.
Can pdfFiller convert PDF to Word?
Yes. Converting PDFs to editable Word documents is included from the Basic edition.
Does pdfFiller include e-signatures?
Not in Basic or Plus. airSlate bundles signNow e-signatures in pdfFiller Premium, which we do not supply; instead you can license signNow separately for the people who send documents for signature.
