pdfFiller is a browser-based PDF editor and e-signature tool from airSlate, the same group behind SignNow and DocHub. Where DocuSign and Dropbox Sign focus on signing, pdfFiller starts at PDF editing — fill fields, redact, rearrange pages, OCR scans — and adds e-signature on top. We picked it because for HR, legal admin, healthcare and government-adjacent teams who live inside PDFs, pdfFiller is one of the few tools that handles the full editing job in a browser without falling back on Adobe Acrobat licences.
How it works
You upload a PDF (or fetch one from a 25M+ form library that includes IRS, USCIS and many state government forms), edit it directly in the browser — type, redact, annotate, rearrange pages, add fillable fields — and either fill it in yourself or send it to others to fill and sign. The signing layer is legally binding under ESIGN, UETA and eIDAS SES, with audit trails and certificate of completion. Documents can be stored in pdfFiller, exported to Google Drive, Dropbox, OneDrive or Box, faxed (yes, real fax) or printed and mailed via partner.
For higher-volume e-signature workflows, airSlate steers customers to SignNow as a separate product. pdfFiller covers most signing needs but is positioned more as a PDF tool that can sign than a signing tool that can edit.
Pricing reality
Basic starts around $8/user/month billed annually for personal use. Plus is around $12/user/month with the form library, eSignature features and basic team management. Premium adds advanced features, redaction and HIPAA on Premium-tier billing. There is a 30-day free trial but no permanent free plan. The honest cost line: airSlate often bundles pdfFiller with SignNow and DocHub at a discount; ask about the bundle if you use more than one.
Versus alternatives

Strength
Weakness vs pdfFiller
pdfFiller
PDF editing + signing in one browser tool
—
Adobe Acrobat Pro
Industry standard, deepest editing
More expensive, desktop-first, slower for collaborative flows
DocuSign
Pure e-sig market leader
No real PDF editing, no form library
Smallpdf
Cleaner UI for casual editing
Lighter signing and form-library coverage
Who should buy, who should skip
Buy if your team works with PDFs daily — HR forms, legal documents, healthcare paperwork, government-form-heavy workflows — and you want a single browser tool to fill, edit, redact, sign and store. The 25M+ form library is a real time-saver if you live inside government and tax forms.
Wait or skip if you only need pure e-signature (Dropbox Sign or Sign.com is cheaper and faster), you need rich design and proposal layouts (use PandaDoc or Proposify), or your team is already standardised on Adobe Acrobat Pro and the migration cost outweighs the saving.

What members say
“Replaced our paper onboarding forms entirely”
“HIPAA compliance on Premium makes it right for sensitive documents”
“Handles our high-volume form workflows at a fraction of DocuSign's cost”
For collaborative and remote-first teams, pdfFiller is more convenient because it runs in the browser, includes a form library and bundles e-signature. For deep desktop editing, prepress and complex PDF authoring, Adobe Acrobat Pro is still the standard.
Is pdfFiller signature legally binding?
Yes. E-signatures are legally binding under the US ESIGN Act, UETA, UK Electronic Communications Act and EU eIDAS at the SES tier, suitable for typical commercial and HR documents.
What is the difference between pdfFiller and SignNow?
Both are airSlate products. pdfFiller is a PDF editor with built-in e-signature; SignNow is a dedicated e-signature platform with stronger workflow and API capabilities. Heavy signing teams use SignNow; PDF-heavy teams use pdfFiller. Many companies adopt both.
Does pdfFiller integrate with cloud storage?
Yes. Native integrations with Google Drive, Dropbox, OneDrive, Box and SharePoint, so signed and edited PDFs land in the storage you already use.
Is there a free plan?
No permanent free tier, but a 30-day free trial covers most evaluations. Basic starts around $8/user/month billed annually after that.
Can pdfFiller handle HIPAA?
HIPAA-eligible BAAs are available on Premium-tier plans. Lower tiers should not be used for protected health information.
