PDF Annotate failed or not working — what can you do?

What you can do

• Open PDF Annotate and retry with a small known-good sample.
• Confirm you are not hitting this limit: Encrypted PDFs are not supported; the full flow is local with no upload.
• Check the FAQ below—encryption, size limits, and format mismatches are the usual causes.
• Still stuck? Try a private window, or read the full guide /#article/pdfannotate.

FAQ

What limitations should I know?

Encrypted PDFs are not supported; the full flow is local with no upload.

When might it fail?

Annotations are drawn into page content (WYSIWYG), not native PDF annotation objects.

What else should I watch for?

Only one annotation can be selected at a time; numbers renumber after delete.

Any other important notes?

For Word / PPT use Word Annotate or PPT Annotate (convert then annotate; export is still PDF; shared editor engine).
