Help & Answers

Frequently Asked Questions

Are my uploaded documents sent to any remote server or stored in the cloud?
No. topdf.click operates entirely inside your web browser using client-side WebAssembly and JavaScript engines. Your document data is never uploaded, transmitted over the internet, or stored on any server.
Can I skip the cover page or start numbering on a specific page?
Yes! Simply turn on the "Skip First Page (Cover)" toggle. Page 1 will receive no page number, and numbering will begin on Page 2 using your configured starting number. You can also specify custom page ranges (like 2-10) to number only specific sections.
How does the "Page X of Y" format work if I skip pages?
You have complete control over total count Y. By default, Y represents the total count of numbered pages in your selected scope. Alternatively, you can toggle the Total Scope setting to use the entire document page count.
Will adding page numbers affect my original text, charts, or images?
No. The underlying document content, vector lines, charts, tables, embedded photos, and searchable text layers remain completely untouched. Only the new page number text and optional background boxes are added.
Does this tool support landscape or rotated pages?
Yes. Our coordinate transformation engine automatically inspects the internal rotation flags (0°, 90°, 180°, and 270°) and CropBox offsets for every page to ensure page numbers always appear upright and aligned with your selected margins.
