Frequently Asked Questions
Yes — completely free, no limits, no watermarks, and no account required. Convertlo runs entirely in your browser using open-source PDF-lib.
You choose: bottom-center (the most common), bottom-right, or top-right. The number is drawn in a neutral gray at a readable size in the margin of every page.
Yes. Set any starting number — useful when a document is a continuation, or when the first pages are a cover and table of contents that you want to skip.
No. Numbering happens locally in your browser. Your files never leave your device, so there is no file-size limit — it is all local processing.
It shows both the current page and the total, like “3 of 12”, which is helpful for printed contracts and reports so readers can tell if a page is missing.
The numbers sit in the page margin in a small font, so on standard documents they do not overlap body text. If your PDF has content right at the edge, choose a position with more clear space.
