PRIVATE, SIMPLE DOCUMENTS

Add Page Numbers to PDF without uploading files

Add page numbers to your PDF with custom placement, starting number, prefix, font size, and optional Page X of Y format. The selected document contents are processed by JavaScript on your device. The CI4 controller delivers the page and assets only; it contains no file-upload endpoint for this tool. Processing can use browser memory, especially for large PDFs or high-resolution page previews.

Browser-side processing

PDF content is read with the browser File API and processed locally by JavaScript libraries.

Control your result

Choose page ranges, export settings, watermark placement, or page number style as applicable.

Download locally

Save the generated PDF or images to your device. Source files remain unchanged.

COMMON QUESTIONS

Frequently asked questions

Are my files uploaded to Infovistar?

No. This tool reads selected files in your browser and creates output blobs locally. It does not send the source files to an Infovistar upload endpoint. The page can still load static resources, analytics, and ads where enabled.

Can every PDF be processed?

Some password-protected, damaged, unusually structured, or very large PDFs may fail because browser libraries have limitations. Try a non-encrypted copy or use a smaller file if processing runs out of memory.

Will the output always be smaller?

No. Some tools change structure without compressing embedded images. Results depend on the source document and selected options.
