Use a small set of non-sensitive documents and a consistent checklist. One successful PDF does not demonstrate compatibility with every file or workflow.
Publish the exact steps and a rights-cleared fixture where possible. Name the environment and limitations. A short, repeatable result is more useful than an unexplained star rating.
Treat redaction separately
Covering text with a rectangle does not establish that underlying information is removed. A redaction claim needs an inspected saved output and an appropriate extraction test. A scoped PDF24 Online result is published on its product page; it covers one synthetic Browser fixture and does not establish every document, desktop edition or removal of metadata.
Use your own acceptance criteria
A designer may require exact visual fidelity; another user may only need searchable text. Decide what success means for the actual task before comparing applications.
Inspect the exact editions
Open the full evidence record before choosing. A documented candidate is not a completed migration test.
