Frequently asked questions
Will it overwrite existing page numbers?
No — the new numbers are stamped on top. If your PDF already has page numbers, you'll see both. Use a redactor first if needed.
Can I start from a number other than 1?
Yes. Set 'Start at' to any positive integer. The first page gets that number and subsequent pages increment by one.
Is the font configurable?
Font size is configurable. Font family is fixed to Helvetica for now — it embeds reliably in every PDF reader.
Are my files really not uploaded?
Correct. Every conversion in this tool runs in your browser using JavaScript and the local file APIs. There is no server-side processing, no file upload, no temporary storage, and no log of what you converted. You can verify this by opening your browser's network tab while converting — the only traffic is loading the page itself.
Do I need an account or to install anything?
No. Open the page, drop your file, download the result. No signup, no email, no extension, no app.
Is there a file-size limit?
Not from us. The practical limit is your device's memory — browser tabs typically handle files in the hundreds of megabytes range without issues. Very large files may take longer to process on phones than on laptops.
