About These PDF Tools

PDF is still the default format for contracts, invoices, and reports, but many quick tasks do not justify installing a heavy desktop app or uploading a private file to someone else's server.

These tools keep the workflow local. PDF Compressor re-saves the document to remove redundant structure, while PDF Merge combines multiple files into a single PDF. Both operations happen in your browser using JavaScript.

Performance still depends on your machine. Large PDFs with many embedded images may take longer to process, but typical office documents are handled quickly and privately.

Frequently Asked Questions

Do I need to install software to use these PDF tools?

No. The available tools run entirely in your browser. There is nothing to download or install.

Are my PDF files uploaded to a server?

Never. Your files are processed in browser memory and are not transmitted anywhere.

How does the PDF Compressor reduce file size?

It re-optimizes the internal structure of the PDF by removing redundant objects and metadata. This works best on files that are not already optimized.

Can I merge more than two PDFs at once?

Yes. The PDF Merge tool lets you add multiple files and combine them into one document.
