How Client-Side PDF Processing Works

When you drop a PDF onto this tool, your browser reads it into local memory (RAM) using the FileReader API. The pdf-lib library - a WebAssembly-powered PDF engine - then manipulates the document structure entirely inside your browser tab.

The resulting merged/split file is converted to a Blob URL and triggered as a download. At no point does any data leave your machine. You can verify this by opening your browser's Network tab - you'll see zero outgoing requests during processing.

For Legal & Medical Use: Under GDPR and HIPAA, uploading sensitive documents to third-party servers can constitute a data breach. This tool is the only legally safe option for processing confidential PDFs online.

Why iLovePDF and SmallPDF Have Limits

Those services process your PDF on their own servers - which costs them real money in cloud compute. So they charge you after 2 free merges, or limit file sizes to under 25MB.

Since this tool has zero server costs for PDF processing, we have:

  • No page limit: Merge 500-page documents
  • No file size limit: Handle 200MB+ PDFs (only limited by your device RAM)
  • No daily usage cap: Merge 100 PDFs in a row
  • No login required: Not one account to create

Frequently Asked Questions

Can I merge multiple PDFs?

Yes! Drag and drop multiple PDF files, reorder them, and merge into a single PDF. All processing happens in your browser.

Is there a file size limit?

No! Since processing runs locally in your browser, there are no server-side file size limits.

Do you store my PDF files?

No. Your files never leave your device. Everything is processed 100% client-side with zero uploads.
