FormatLab runs the same document set through every PDF tool we test and logs the results — conversion accuracy, OCR speed, and feature coverage, measured the same way every time.
Test conditions: identical document set (scanned contract, multi-column report, spreadsheet export, fillable form), run on matched Windows and macOS hardware. Scores combine conversion accuracy, OCR speed, and feature coverage. Full methodology on the About page.
Each score reflects testing across the same document set — not marketing claims or vendor-reported numbers.
Highest composite score in this run — full editing and OCR with no cost gate.
View log →Strongest on redaction and column-layout detection; loses points on cost-per-feature.
View log →Solid batch-processing throughput, slightly behind on multi-column conversion accuracy.
View log →Fastest load time in the run, but free-tier feature set is narrower than competitors.

Notes from the testing process — practical, not promotional.
Which "free" tiers are actually free, and which ones are a trial with extra steps.
Read log →Different workloads need different tools — coursework vs. contracts vs. signed agreements.
Read log →Where conversion accuracy actually breaks down, and which tools held structure.
Read log →Password protection, permissions, and redaction are three different things — here's what each does.
