About this add page numbers to pdf
Add sequential page labels to a local PDF. Each page receives a black 10-point label in the format page / total, centered near the bottom of its crop box. Use this workspace to prepare a result you can review before putting it to use. All processing takes place on your device, without an account or an upload of your inputs. Check the examples to understand the expected output, read the limitations for the supported scope, and reset the form when you want to start a separate task.
