FormatLab exists because "best PDF editor" lists rarely say how that conclusion was reached. We log what we test, how we score it, and what the score does and doesn't measure.
Each tool's composite score is built from three weighted categories, tested against the same fixed document set every run.
How closely the output (Word, Excel, image) preserves layout, tables, and formatting from the source PDF.
Whether editing, OCR, batch processing, and security tools are present — and whether they're gated behind a paywall.
Load time, export time, and how the application handles large or scanned files without freezing.
FormatLab earns a commission on some outbound links. We separate that from scoring on purpose: commission rate is not an input in any benchmark formula, and a higher-commission product does not get a score adjustment.
Only re-running the test suite changes a score — a new software version, a fixed bug, or a fresh benchmark cycle. Nothing about a partnership agreement enters that calculation.
