Their starting prices are not directly comparable: pdfFiller lists $8/month with annual billing ($96 upfront), while eFax lists €7.99 monthly or €6.66/month billed annually (€79.90 upfront). Neither lists a free plan. pdfFiller lists a 30-day trial; eFax trial availability is not published. Check page allowances and fax add-ons before buying.

02Pricing compared
The starting prices are in different currencies, so compare them without converting: pdfFiller lists Basic at $8 per month with annual billing, or $96 billed upfront. Its monthly rate is $20. eFax Plus costs €7.99 monthly or €79.90 upfront for a year, which the pricing page presents as €6.66 per month. Neither product lists a free plan. pdfFiller lists a 30-day trial; eFax trial availability is not published.
pdfFiller’s listed annual rates rise to $12 per month for Plus and $15 per user per month for Premium. Inbound fax is an add-on, priced from $9.99 to $19.99 per month depending on plan. eFax Plus includes 30 sent and 30 received pages monthly; Pro costs €10.99 monthly or €109.90 annually and includes 150 pages each way. Both products leave some costs unclear: pdfFiller does not publish usage limits or overage costs, and eFax does not list page overage rates.
03Features and depth
These products solve different problems. pdfFiller is for working with PDFs: its listed tools cover editing text, highlighting and redacting, adding images, signing, building fillable forms, and merging, splitting, or rearranging pages. It also supports sharing documents and templates, collaboration, conversions, and role-based signing workflows. The feature list describes a document workflow, not a replacement for a dedicated online fax service.
eFax is built around sending and receiving faxes without a fax machine or phone line. It supports faxing from internet-connected devices and through email, and Plus and Pro include a local or toll-free number. The plans include fixed monthly send and receive allowances, while Corporate offers customizable volumes, API integration, and individualized support. For broader workflows, eFax lists AI data extraction from inbound faxes, scans, and PDFs, plus CRM, ERP, and EHR integrations. Its Conductor and Unite products support FHIR, HL7, REST, and DirectTrust. Choose based on the job: document editing and signatures favor pdfFiller; fax delivery and integrations favor eFax.
04Ease of use and learning curve
For a user who mainly edits or signs PDFs, pdfFiller’s browser and mobile tools keep the work in one document platform. Its feature list includes fillable-form creation, page management, and sharing, but usage limits are not published. The review notes reported save paywalls, so check the trial and terms before moving a recurring workflow.
eFax’s core task is narrower: send or receive a fax from a device or email account. That may be a simpler fit for occasional faxing, but track monthly allowances: Plus includes 30 pages sent and received, while Pro includes 150 each way. Corporate adds API and admin-oriented options, which may require more setup. The pricing page says faxes continue to send after page limits, but does not publish overage rates.
Questions people ask
Is DocHub the same as pdfFiller?
The available product information describes pdfFiller as a cloud PDF editor and document-management platform, but it does not describe DocHub. We can’t confirm whether they are the same product from these details. Compare their current features and terms directly before switching.
How do you fax from pdfFiller?
The published details list inbound fax as an optional pdfFiller add-on, priced at $9.99 to $19.99 per month depending on plan. They do not explain a fax-sending workflow or whether outbound fax is included, so confirm those points with pdfFiller before relying on it for faxing.
Can pdfFiller be trusted?
The available review rates pdfFiller 5.8 overall and notes reports of paywalls when saving. That is a reason to check the trial and billing terms, not enough evidence to establish whether the service is trustworthy. The published information does not include security or reliability findings.
Is pdfFiller HIPAA compliant?
The pricing details list a HIPAA compliance add-on for Enterprise, but do not publish its price or explain its scope. They do not establish that every pdfFiller plan is HIPAA compliant. Ask pdfFiller which Enterprise plans qualify and what the add-on covers before handling regulated information.
