Are my PDF documents uploaded to your server when merging or splitting?

No. All PDF operations (merging, splitting, rotating, numbering, and watermarking) occur entirely within your web browser using client-side JavaScript. Your files are never uploaded.

Can I add page numbers to an existing PDF?

Yes. The PDF Page Numbers tool allows you to stamp numbers onto the top or bottom of every page, with custom formatting, font size, and margin controls.

How does in-browser PDF compression work?

The Compress PDF tool strips unneeded metadata and redundant structural elements from the PDF stream while maintaining legible text and vector graphics.

Can I extract files from a ZIP archive on a phone or tablet?

Yes. The Unzip tool runs on any modern mobile or desktop browser, allowing you to preview and download individual files from ZIP archives without installing extra apps.

Private, in-browser PDF manipulation & archive utilities

Managing documents and file archives shouldn't require expensive software licenses or uploading sensitive contracts to unfamiliar web servers. Convert369's Document & Archive Processors give you full control over PDF files, Excel workbooks, ZIP archives, and text diffs directly in your browser. Rearrange pages, reduce file sizes, apply copyright watermarks, and extract files with zero waiting and zero cloud storage.

Complete Document Privacy for Legal & Financial Records

Tax documents, medical histories, and signed contracts contain confidential personal data. While legacy PDF web converters upload files to remote third-party servers, Convert369 processes PDF pages and ZIP archives directly in your browser memory using PDF-Lib and JSZip. Your documents never leave your device.

Comprehensive PDF Page Manipulation

Split multipage PDFs into individual files, extract specific page ranges, rotate sideways scans 90 or 180 degrees permanently, delete blank pages, and stamp sequential page numbers with custom font sizes, alignments, and starting offsets.
