Editorial principles and source statement

1. Write for a decision the reader can verify, not for a keyword count.
2. Separate measured behavior, standards-based facts, informed cautions, and untested assumptions.
3. Name destructive, lossy, rasterizing, security, accessibility, and compatibility trade-offs before the action.
4. Never claim certification, universal support, losslessness, identity verification, OCR, repair, or structure preservation without evidence.
5. Use original prose and examples; competitor pages inform conventional workflow coverage only.

How sources are used

Primary sources are preferred for factual format and platform behavior. Product implementation and deterministic fixtures are the authority for what Image PDF Tools itself does. Competitor prose, screenshots, icons, ratings, examples, and expressive assets are not reused.

• Published standards and format registries
• Browser and framework documentation
• Upstream library documentation and license texts
• Repository code, tests, fixtures, and third-party notices
• Live destination requirements supplied by their responsible authority
