What this tool does
Number reports and attachments without changing the original. The sequence advances across the selected pages.

Common mistakes
- PDF up to 5 MiB/50 pages; text size 8–72 pt; output 20 MiB. The mark must fit the visible area.
- Editing may invalidate signatures. Helvetica supports compatible Latin text; this is not redaction or a guarantee of all advanced PDF features.
If an error appears, reduce the input or correct the specified field. Do not treat an unsuccessful operation as a valid result. Repeat the example with synthetic data to separate an input problem from a tool problem.
Limitations and privacy
Inputs are processed in your browser. Visiting the site downloads its resources, but the tool does not upload the document or text. Results are not automatically stored. Check downloaded files before using them in a workflow.
Editing a PDF may invalidate digital signatures and does not sanitize its active content. This guide does not promise preservation of every form, attachment or advanced document feature.
