SendItFax Only Supports 3 File Formats — Fax 15+ for $3.50
SendItFax lets you fax DOC, DOCX, and PDF for free (3 pages max). Need to fax a JPG, PNG, Excel spreadsheet, or anything with HIPAA compliance? $3.50 flat, 15+ formats, pay only on successful delivery.
SendItFax is a genuinely free fax service for short documents — 3 pages, no account, no trial trap. That works if you have a single-page PDF to send. But if your document is a scanned JPG, an Excel spreadsheet, a multi-page insurance form, or anything containing Protected Health Information, SendItFax can't help. OneFaxNow accepts 15+ file formats, handles up to 50 pages per fax, and offers HIPAA compliance with an instant, fully executed BAA — all for a flat $3.50.
TL;DR: Choose SendItFax for a quick 1–3 page PDF or Word doc at no cost. Choose OneFaxNow when you need image support, more pages, HIPAA compliance, or pay-on-success delivery assurance. SendItFax pricing verified on senditfax.com.

SendItFax vs OneFaxNow: Common Questions
Is SendItFax really free?
Yes, for short documents. SendItFax offers a free tier limited to 3 pages per fax (plus a branded cover page) with a 5-fax daily limit. Their paid tier is $1.99 per fax for up to 25 pages with no branding. OneFaxNow charges $3.50 flat for up to 10 pages with no branding and pay-on-success guarantee.
Does SendItFax support HIPAA compliance?
No. SendItFax explicitly states it is "not built for sending regulated data" and does not offer HIPAA compliance or a BAA. If you need to fax patient records, insurance claims with PHI, or other regulated documents, OneFaxNow offers HIPAA mode with an instant, fully executed BAA starting at $6.50 per fax.
Can I fax images or photos with SendItFax?
No. SendItFax only accepts DOC, DOCX, and PDF files. If you need to fax a JPG, PNG, TIFF, or phone photo, OneFaxNow supports 15+ file formats including all major image types. iPhone users can even fax HEIC photos directly through the OneFaxNow mobile app.
What happens if my fax fails on SendItFax?
SendItFax provides delivery confirmation but does not clearly disclose whether you are charged for failed deliveries on the $1.99 paid tier. OneFaxNow uses authorize-then-capture: your card is authorized upfront but only charged after the fax is confirmed delivered.
Can I fax more than 25 pages?
Not with SendItFax — their maximum is 25 pages even on the paid tier. OneFaxNow supports up to 50 pages per fax across up to 15 uploaded files (20MB each), with automatic file merging.
Does SendItFax have mobile apps?
SendItFax is primarily a web-based service. OneFaxNow offers dedicated native apps on both the App Store (iOS) and Google Play (Android), plus a full web interface for desktop browsers.
Is OneFaxNow more expensive than SendItFax?
For a simple 1–3 page PDF, SendItFax is cheaper (free). But for anything beyond that — more pages, image files, HIPAA compliance, or delivery assurance — OneFaxNow's $3.50 flat rate provides significantly more value. SendItFax's $1.99 paid tier maxes out at 25 pages; OneFaxNow covers up to 50 pages for $5.00.
