- Cross-platform, with a genuinely free validator (Desktop Lite)
- Strong auto-tagging engine and an SDK for automation

Two answers to the same problem
PDFix is a Slovak company with a strong engineering culture and an honest product. Its free Desktop Lite validator is one of the reasons this market has any transparency at all.
The difference is philosophical, and it shows up in the defaults.
PDFix leans toward automation. Auto-tag, auto-detect structure, auto-fix, then review. On a large volume of similar documents that is the right shape, and the throughput is real.
Taggart leans toward evidence. It reports what it found, tells you which conditions the protocol says need a human, and refuses to guess where guessing would be silent. Its auto-tagging exists but will not run without you confirming that you understand what it produces.
Neither is wrong. They suit different work. If you are pushing a thousand similar forms through a pipeline, automation is what you want. If you are remediating documents that each differ, and you will have to defend the result, the second shape saves you the re-review.
The concrete differences
Right-to-left. PDFix has no visual-order detection. This is the one that is not a matter of taste: a Hebrew document with reversed storage is broken in a way PDFix cannot see. What that failure looks like →
The appearance gate. Taggart re-renders every remediated file and compares it to the original at SSIM ≥ 0.999 before returning it. PDFix does not publish an equivalent guarantee. In practice both are careful, but one of them can prove it on every single file.
The report. Taggart’s remediation report includes a timestamped log of every human decision — who accepted what, and why. For a compliance file that is the artifact that matters, more than the remediated PDF itself.
The honest summary
PDFix and Taggart agree that checking should be free. They differ on what comes next: PDFix leans on automation, Taggart on giving a specialist a faster set of hands and an audit trail.
Frequently asked questions
PDFix Desktop Lite is free. Why would I pay for Taggart's validator?
You would not, and you do not have to — Taggart's validator is also free and unlimited. Both companies reached the same conclusion: checking is commoditised. Run both if you like; where they disagree is informative, and Taggart documents known disagreements in its rule file.
Is PDFix's auto-tagging better than Taggart's?
It is more aggressive, and on simple documents it produces a usable result faster. Taggart's auto-tagging is deliberately cautious: it wraps untagged content in painting order, refuses to run without explicit confirmation, and tells you in the change log that painting order is not reading order. Which behaviour you want depends on whether you would rather fix a wrong guess or make the call yourself.
Does PDFix handle Hebrew?
It processes Hebrew documents. It does not detect visual-order storage, so a Hebrew PDF that reads backwards will be tagged, checked, passed, and still read backwards.
What about the PDFix SDK for automation?
It is a serious product and there is nothing comparable in Taggart today — the CLI in the Pro tier covers CI pipelines, not embedding. If you are building remediation into a document management system, PDFix is the right vendor.
Try it against the same file. Taggart's validator is free and unlimited, so you can run your own document through both and compare the findings before deciding anything.
