Free Online PDF Tools

Compress, merge, and convert PDFs without leaving your browser. Your documents stay private — nothing is uploaded.

About These PDF Tools

PDF is the universal document format, but editing one has traditionally required desktop software like Adobe Acrobat or a paid online service that wants you to upload your files. Both options have problems. Desktop software is expensive and slow to install. Upload-based services raise privacy concerns, especially when you are working with contracts, financial reports, or personal documents.

These tools take a different approach. They use pdf-lib, an open-source JavaScript library that parses and generates PDF files entirely inside your browser. When you drop a file into the PDF Compressor, the library reads the PDF byte stream, strips redundant objects and metadata, re-encodes the document tree, and hands you a smaller file. The original never leaves your machine.

The PDF Merge tool is useful when you need to combine invoices, reports, or scanned pages into a single document. Add your files, drag them into the right order, and download the merged result. It handles documents with different page sizes and orientations without breaking the layout.

Conversion between PDF and text documents is covered by two tools. Word to PDF converts text content into a clean PDF you can share with anyone, while PDF to Word extracts text from a PDF so you can edit it in a word processor. The text extractor works best with PDFs that contain selectable text rather than scanned images.

Because browser-based processing depends on your device hardware, very large PDFs (hundreds of pages with embedded images) may take longer to process. For typical office documents — contracts, reports, invoices — the experience is nearly instant. No account needed, no file size limits, and the results are yours to keep.

Frequently Asked Questions

Do I need to install software to use these PDF tools?
No. All four tools run entirely in your browser. They use pdf-lib, a JavaScript library that reads and writes PDF files on the client side. There is nothing to download or install.
Are my PDF files uploaded to a server?
Never. Your files are processed in your browser's memory and are not transmitted anywhere. Once you close the tab, the data is gone. This makes the tools safe for sensitive documents.
How does the PDF Compressor reduce file size?
It re-optimizes the internal structure of the PDF — removing duplicate objects, cleaning up metadata, and streamlining the document tree. The compression is lossless, meaning text and vector graphics stay identical.
Can I merge more than two PDFs at once?
Yes. The PDF Merge tool lets you add as many files as you need. You can reorder pages by dragging them before generating the final combined document.
What does PDF to Word actually extract?
It extracts the text content from your PDF. The output is a plain text file you can open in any word processor. Complex layouts, images, and custom fonts are not preserved — this tool is best for text-heavy documents.
