Does numbering affect PDF quality?
No. PDFSuite uses pdf-lib to add text directly onto each page without re-rendering the content. Original text remains selectable, images maintain their quality, and file size barely changes.
Can I start numbering from a number other than 1?
Yes. You can set the starting number from the 'Start number' field. This is useful if your PDF is part of a larger document and you need to continue the numbering.
Is there a size or page limit?
No artificial limits. You can number PDFs of any size with any number of pages. The only limit is your browser's available memory.
Are my files secure?
Yes. All processing happens locally in your browser using JavaScript. Your files are never uploaded to any server. Once you close the page, all data is cleared from memory.
Can I number password-protected PDFs?
Not directly. Password-protected PDFs need to be unlocked first. If you have access to the original unprotected PDF, you can number it directly.
What font is used for the numbers?
Helvetica is used, a standard font built into all PDF readers. This ensures numbers display correctly on any device without embedding additional fonts.
